Short versionDrayton Wiser is one of the cheapest internet-enabled heating control systems available but in many ways, it is the best, regardless of price. I’ve only been using it for a few weeks, but so far it has been brilliant. Only 4 stars, as Drayton say it doesn’t currently support underfloor heating, but more on that below.Long versionWhy Wiser? At this time it appears to be the only system which can control multiple heating zones and hot water from a single controller. When I say “zones”, I mean truly separate plumbing zones, each with its own independent motorized value. The controller, or “Hub”, can also control many wireless thermostatic radiator valves (TRVs), giving individual room control,as well as offering wireless room thermostat control.By contrast, the Honeywell Evohome seems overly complicated, requiring many components to make a comparable system work. The TRVs are too big, and while it might seem nice to see a temperature reading on the TRV, it isn’t necessary and will just cause the batteries to run down faster.By contrast, the Wiser thermostats and TRVs are minimalist, but provide all the functionality you need.The Hive thermostats also appear overly complicated and likely to drain their batteries quickly if you use all that functionality frequently. The Hive system would also require a second Hub to control a second zone. It also requires yet another unit to receive the wireless signal from the Hub and connect to your WiFi modem via a cable. The Wiser Hub connects directly to the WiFi modem wirelessly.So Wiser was a clear winner for my needs. What tips would I give to anyone thinking of buying Wiser?Hardware InstallationThis was simple in my case, as I already had a Drayton LP722 controller for the hot water and central heating. I had a separate Danfoss TP5 controlling an underfloor heating zone. Wiser Kit 3 is required for two zones plus hot water. The Wiser Hub uses the same UK industry standard backplate as the LP722, so it was just a matter of removing the LP722 panel (2 screws), moving the two wires for hot water and central heating from terminals 3 and 4 to terminals 2 and 1 respectively, attaching the output wire from the TP5 to terminal 3, and finally attaching the Wiser Hub to the existing backplate using the same two screws. Drayton could have made this even simpler by using terminal 4 for a heating channel, terminal 3 for the hot water, and terminal 1 or 2 for the second heating channel. The screws are on the underside of the Hub, so you need some clearance below to get a screwdriver in. If there isn’t much clearance I recommend a mini-ratchet, like this one: https://www.amazon.co.uk/dp/B002VJ7K88/ref=pe_3187911_185740111_TE_itemAfter installing this I discovered a statement on the Drayton FAQ page that Wiser does not currently support hydronic underfloor heating. This was disappointing, as it wasn’t mentioned anywhere on their product selector or other pages at the time. The reason is that the software in the Hub uses a “load compensating” algorithm, designed for radiators. In other words, it will start to switch the demand for heat on and off as it gets close to the required temperature, whereas underfloor works best with a simple on/off algorithm. That said, I’ve left the Wiser controlling the UFH zone, and it seems to be working fine so far. Their support team also informed me that they will be adding official UFH support in a software update later this year.I didn’t install any smart TRVs at this stage, but I have done this subsequently and they work well. It was easy to replace the old Danfoss TRVs as the Wiser ones come with a Danfoss adapter collar. One small hex key was the only tool required to remove the old TRVs and attach the new ones.The Hub is in a cupboard and the WiFi modem is in a different room, so the signal has to go through three wooden doors and round some corners in a Victorian house with thick walls. I haven’t had any problems with WiFi connectivity to the Hub. One of the smart TRVs is 3 rooms away and just out of range. This was easily fixed by using a single Wiser range extender plug at half distance between the Hub and far radiator. The Hub communicates with TRVs, room thermostats, and plugs using the Zigbee wireless standard. This is completely separate from the WiFi but does use a similar carrier frequency. Its range seems to be similar to the WiFi in my house.If you have a large room with multiple radiators it will work best if you also place a room thermostat in this room, as it will give a more accurate temperature reading than the TRVs. In this case the Hub will use the room thermostat reading to control the TRVs. You should also use a room thermostat if you have radiators with TRVs inside a radiator cover.The price can start to mount up as you add more TRVs, room thermostats, and plugs; however you can do this gradually, and it is still much cheaper than trying to achieve the same functionality with other systems.Software InstallationI read a lot of negative reviews about the software app set-up process, as well as many positive ones, so I was a bit worried about this stage. I shouldn’t have been. The process was very slick and the whole thing was up and running in 5 minutes. Having read some of the other comments I did a couple of things to prepare for the installation that might have helped make it a smooth process:1. Make sure your phone is connected to the 2.4GHz carrier on your WiFi modem. Most modern phones will try and connect to the 5GHz carrier if they can, as it can potentially have a higher data rate; however most Internet of Things devices that don’t need high data rates (e.g. heating Hubs) will use the 2.4GHz carrier, as it has a better range than 5GHz. The Wiser Hub uses 2.4GHz WiFi to communicate with your WiFi modem. During the set-up, your phone will need to be connected to exactly the same WiFi channel as the Hub. You can check if your phone is connected to 2.4GHz by looking in the WiFi settings. If it’s 5GHz you might be able to get it to switch by moving the phone further away from the modem. The best way is to log in to your modem settings page and change the WiFi name (SSID) for the 2.4Ghz channel to something different to the 5GHz carrier. You can then “forget” the 5GHz WiFi in your phone WiFi settings and connect to the 2.4GHz WiFi. This should also give you the advantage of a more reliable WiFi connection around your house, as some phones don’t seem to be very good at auto-switching from 5GHz to 2.4GHz when they start to lose signal.2. In your WiFi modem settings, make sure the modem is not blocking any ports.3. Have another device such as a laptop close by with your email open. You will be sent an account registration confirmation email during the set-up process. You need to click something in this email but apparently this might not work if you try to do it on your phone during the set-up.Apart from that I just followed the instructions on the app. Within a few minutes I had all the rooms and hot water configured with daily schedules. It has worked flawlessly since then.OperationThe app seems intuitive to me. It is easy to set up schedules for different rooms and copy them from day to day. The heat report feature is nice to see graphs of temperature over time for each room. The graphs also show the schedule target temperature. It would be useful if the graph could display when the Hub is calling for heat as this isn’t as simple as when the actual temperature is below the target temperature. They could use a small icon on the header bar for the heat report rather than taking up a lot of screen space with the button for this, outside temperature, and reminder of where you are, in case you forgot.I haven’t used the eco or comfort modes, which try to predict when to turn the heating off and on to reach your target temperature by the scheduled times. I have a good idea about this myself already and just set the schedule to come on early enough.I use the app for all control and checking the room temperatures. It works well wherever I am in the world, on WiFi or mobile data. I find I never need to touch the room thermostats or TRVs. I suppose those controls might be handy if the internet is ever down, but it is also possible to connect your phone directly to the Hub WiFi by pressing the Hub setup button.In summary, it looks like Drayton has really thought about the design of this system. It is very powerful, but very simple to install and use.

It's been a few months since I installed our wiser system with seven TRVs. The actual installation of the hub was relatively easy as there was a first generation Hive system installed when we first moved in. The back plate was not quite the same so I copied the wiring from the old back plate to the new one, plugged it in and all good.That said. I could not register an account at first. This was/is a common issue for some people that I hope Drayton has since resolved. I tried everything and eventually had to phone the Drayton Wiser people who were actually very good. The issue was fixed by having to set up my wireless router to 2.4ghz only as they were having issues with the 5ghz range (nonsensical but).I was not happy about this at all as I have 5ghz capable devices in the house. I also had to set up a port on the Virgin router and how to do this wasn't explained to me so I had to trawl the internet to figure out how to do this. It turns out this process was literally to patch up a bug in their own system. A few weeks after this I had a new Super Hub (crap) 3 installed from Virgin and installed an R7000 router to replace the poor wifi single/handling from the Virgin box. I was worried that I would have to disable 5ghz and muck around with port numbers again but it just worked as before so I think this was a registration bug that they may or may not have sorted out. One more thing I will say is that although the the techs you speak with on the phone seem well educated in their own system and equipment (take note Virgin Media!!) If you are on the phone for a while with them they tend to get a bit fidgety about the time they've been trying to sort the problem out with you so i'm wondering if they have a clock where they are expected to try and politely move you along so they can take the next call? This was a pattern that formed over the three or four phone calls I had with them. The above reasons are why I generally gave four stars as I don't think buggy registration should result in people having to turn off 5ghz networks in their homes. On to the system itself…I spent about eight months researching the different smart heating systems on offer and in the end, it was a toss up between the Tado system and the Drayton Wiser. The much reduced price of the Drayton was appealing and the fact that Tado gave me a very poor quote for the equipment I needed, including a box that I simply didn't need, so that was it for me and Tado for the time being.The Wiser system has been a revelation to us. It's very easy to use the app so scheduling and just turning the heating up and down is very simple. Both myself and my GF can turn on the heating from our phones before we get home (no wifi required) which is super handy. So far the system has been completely reliable and a joy to use.The TRV's themselves are very solid and easy to add to the system via the app. They are a little noisy though but I actually see it as a confirmation sound that they are opening or closing. I have only ever noticed noise from them when the heating for that TRV first gets turn on or turned off. In general operation I have never heard a peep out of them. Some people's experienced may vary but the noise is not an issue for us.Probably the biggest thing I have noticed from this system versus a normal manually controller TRV system is that the temperatures are a lot more consistent. As each TRV is essentially a motorised valve with a thermometer in it, you get very consistent room temperatures that adjust based on that rooms temperature. I think this is where some of the heating cost savings could be made. That as well as only heating rooms that you want to heat without having to manually turn off radiators all the time.So. This is a small list of things that you should know which I have discovered during our short ownership that I hope will be useful.10th Dec 2018.1. Alexa does work with the heating but after one hour it reverts back to where it was, ignoring your command from an hour before. Why this is the case I simply don’t know. It’s very annoying so we don’t use Wiser and Alexa together. any more The other Alexa issue to note is if you tell her to turn off the heating, she reduces it down to 10 degrees C. I discovered this when I set an Alexa ‘Routine’ to switch everything off in the house. Lighting, wall switches and heating etc. I called the routine “Goodnight” so I knew that when we go to sleep that everything is off. On checking, all the TRVs had defaulted to 10 degrees. I have not figured a way around these disobediences.2. Whilst swiping from room to room in the app, at the bottom right there is a switch to toggle between MANUAL and SCHEDULE symbolised by a hand icon or a calendar icon. If you leave this is manual (hand) and your internet goes down for any reason, ALL the heating comes on at full and you literally have to switch the main hub off at the wall until the internet starts working again. If you have a schedule set then it will apparently revert to the last known settings (double check this) but as I had not set up any schedules at that stage it just turns everything on at full.. This is an alarming choice by Drayton and something I hope they look at more sensibly. Especially if you get nervous about it if you’re away for any period of time.3. It’s nice that you get a set of half decent batteries with every TRV but one set of them lasted about a month for some reason so I had to replace with our own despite it reporting that the batteries were full, the voltage across them suggested they were nearly depleted.All in all, I have no regrets about choosing this system. It’s easy to use, well made and the app is simple and quick. There are obviously some bugs in the system but I get the impression that they are always working to fix issues. The hub updates itself on its own which is potentially handy. The ease of being able to set (even remotely) each room with it’s own tailored temperature is one of it’s best features so if you are planning to install this then make sure you get one of their TRVs for each room otherwise the system simply is incomplete.UPDATEI thought i'd write an update on a little issue people should be aware of and that is of some battery issues we've had. One of the TRV's batteries only lasted a few weeks and despite reporting it was at 100% it then died reporting critically low battery. This has now happened with three of the TRV's so their claim of a two year battery life is odd. My GF mentioned the other day that the main bedroom was stiflingly hot and although the app said that the heating was off in there, it wasn't. The radiator was very hot. I took the TRV off and pushed down the valve (which is quite new) and it worked perfectly. I refitted the batteries, re-calibrated the TRV and it still wouldn't push the valve down far enough to close the radiator off. New batteries and it worked first time and has been fine since. Whether this is just down to cheap batteries that come supplied or not I don't know but just make sure you keep some decent quality (Energiser and Duracell are just names and don't guarantee a decent battery so don't be fooled) AA's around as this seems to sort out most issues NOT reported as battery issues by the system.

I am writing this review after using this product for couple of months. So, apologies for long review in advance :)I have a newly built 4 bed room town house (3 floors). I have 2 heating circuits with 2 room thermostats and a hot water tank with a thermostat. Lounge is on one heating circuit and rest of the house is on other heating circuit. I have ESI programmer, ESI room thermostats and Hot water thermostat.My requirements were:1) Independent room temperature control - Met2) Easy installation without major wiring changes - Partially met3) Geo fencing - Met with IFTTT4) Amazon Alexa integration - Met but with limited operations.5) Energy saving - Met6)Opentherm interface - Opentherm itself is not compatible where the system has a hot water tank with external water temperature thermostat. So even though my boiler has opentherm module, the system won't work with my setup. Opentherm enables wiser to control boiler temperature in real time to reduce the gas consumption.Why I chose this kit?I did a lot of research in this area and I found the following1) Google nest: No seamless way of having individual radiator thermostat temperature control. We can use Energenie smart TRVs with MI software but the integration is clunky and unrealistic.2) Tado : Features like Geofencing are subscription based which is not a great way to save money.3) Hive: Although it is possible to install smart radiator thermostats to get individual room heating control, reviews suggest that the radiator TRVs are taking 1 hour to turn on. Recently hive released a firmware update to reduce this time to 30 minutes. This defeats money saving objective. Also, the radiator TRVs don't have the same priority as the room thermostats. This way, if the room thermostat reaches target temperature, even if TRV calls for heat it won't work.Some information about the wiser system:I purchased wiser kit 3 (Comes with Wiser hub, 2 room thermostats) and I purchased 4 radiator thermostats separately.Wiser hosts a 2.4 Ghz radio network to communicate with room thermostats and radiator thermostats.It is advised to use a 2.4 Ghz wireless home network with WPA2 security (But it worked ok with my dual band wifi network which hosts 2.4 Ghz and 5 Ghz frequencies with same SSID).Installation procedure and issues I faced:Note: It is important to know TRVs which are linked to specific heating circuits before starting the installation process.Step 1) It is advised to remove the existing room thermostats and short the call for heat wire so that the thermostat calls for heating all the time. I achieved this by simply turning the thermostat to maximum temperature so that it is calling for heat all the time.Step 2) I had ESI programmer which I removed from the back plate. The back plate of ESI programmer is different from wiser's back plate. I had to removed the cables from existing back plate and labelled them. Then I removed the existing back plate, installed the wiser back plate and connected the cables to wiser back plate as described in the manual.Step 3) After the wiser controller turned on, it hosted a wireless network. I installed wiser heat app on my android phone and from wifi settings, connected to the wifi network hosted by wiser hub.Issue 1) Android system detects that the wifi network hosted by wiser hub is not providing internet connection and requests the user to switch wifi. While this prompt is open, wiser heat app can't find the wiser hub. So, I had to select the option on wifi settings to stay connected to wifi network hosted by wiser. After this the wiser heat app found the wiser hubStep 4) I paired the room thermostats and Radiator thermostats with wiser hub via the wiser heat app and started installing the radiator TRVs.Issue 2) After pairing the radiator valve with the wiser hub, I went to the top floor to install the radiator thermostat. After the calibration started, the mobile phone lost wifi connection with wiser hub due to poor signal and the configuration failed. So, I came back to ground floor, connected to wiser wifi network and then completed the setup. This resolved the issue.Step 5) After pairing and installing room/radiator thermostats, we have to connect the wiser hub to home wifi network which is by far the most painful step of all.Issue 3) I hosted a 2.4 Ghz wireless guest network with WPA 2 network security as advised in the manual. I tried 10 times to connect wiser hub to this guest network but it failed every time. Ironically it connected to my dual band home wifi network (Which hosts 2.4 Ghz and 5 Ghz frequencies with same SSID/wifi network name) with WPA/WPA2 security with no issues.Step 6) Created new account with email address etc. This completed without any issues.General issues reported by users.Some users reported that Wiser system has issues in homes with Philips hue lighting system. But I didn't face any issues as I have Philips hue lighting at home.I called wiser technical support to know the signal strength of my radiator TRVs. They told me that I don't need to worry about signal strength until the TRVs show offline frequently in wiser heat app. So far, I didn't see any issues.The TRVs make some noise when they turn on and turn off. As my kids are older, I am not finding this as a real issue.Look and feel of wiser heat app.This app is functional but not flashy. It has everything that we need from a Smart heating system. If you are someone who can figure out things by using apps, then it should be a breeze for you.Advise to product team:The wiser hub power led blinks in the same way when it loses wifi connection and when it is updating the firmware. This won't help the user to understand what's wrong. Please change the power led blinking pattern so that we can distinguish the difference.The Alexa integration provides very basic functionality. Please add functions to alter heating schedules.In the next version of Radiator TRVs, try to reduce the noise.Final verdict:This is by far the best smart heating system for the price in the market but to set this up and use it, user must have a troubleshooting mindset. So, non-technical users must opt for professional installation :)

We have a house with solid walls. Some rooms are warm and stay warm, others go cold really quickly.We had a Worcester 34cdi with old drayton RF controller built in, and at night the bedrooms used to drop way below the setpoint of the wall thermostat - not great for kids bedrooms, so had been looking at Smart control systems.This kit came on a treasure truck offer few months ago so bought it, plus 3 additional radiator valves.Had to arrange an electrician to install the wall plate and the hub to the boiler... £60ish and less than an hours work.The rest is done via the app on your phone.Positives:-Responsive accurate control of the system-Able to have a temperature zone everywhere you have a sensor-You can create a schedule of times/temperatures and assign multiple rooms to that schedule,or you can have a schedule per room (as we do as our use of each room fluctuates).- Radiator valves (TRVs) *very* easy to install and setup (just observe the battery polarity markings!... as the typical "springs" arent the same as other appliances... I spent 30 mins trying to figure out why none of my valves was powering on...to see that the batteries were in wrong!). TRV up/down can trigger a 2c boost for 1hr for that zone.- If you have a TRV and wall control in a single zone then the wall control automatically overrides the heating-demand on the TRV itself.- TRVs are simple in that there is no pull out display like the honeywells. Just boost up/down twists to change current setpoint.- Not too loud... slight whir for split second when temps adjusting... eg if too cold you hear the valve open, then the heating comes on. If the boiler is on and they dont want heat... then they whir shut.- Make sure your valve-body pins are free... get pair of pliers and shift up down a few times with a little wd40 so the motors dont have quite as much work to do.- We have solid walls, but didnt need the range extender. Furthermost valve needed to be connected to hub a bit closer, but always responds to control now connected.- android app is intuitive and easy to make changes in; there are now also battery status bars for each device and alerts when getting low. Plenty of insights of how your house behaves thermally, compared with say the outside temperature and what rooms heat when. (Mine is saying to install a TRV in our lounge as we are overheating it constantly as its an "always on" radiator - which had suspected).- comfort mode works out over time what your room takes to heat vs outside weather and turns on the heating before scheduled time so it reaches the set point when youve told it to. Works pretty well IMO.- there is a "eco" mode but not tried it out. Apparently its turned our heating down quite a few times when not needed... time will tell if reduces bills, but we bought it more for comfort so that we didnt have to wake up in middle of night to turn heating up for the kids.- hub range pretty decent. Our hub is in our outhouse round back of house and we still get 2/5 signal upstairs at front of house; the rad valves seem to maintain decent connection just the app sometimes struggles.Negatives:ipad app:- layout... doesnt landscape when you turn the screen- doesnt have the "settings" options... for that I have to use my android phone... so wouldnt have been able to setup using our ipad. Also doesn't work with older ipads (we have a mini it wont install on, which might have been useful to just put on a wall in the hallway)Android app:1. latest update... if low signal to the hub it sits waiting to connect to the hub before you can change any settings... previously you could go in, review and only when you came to change something would it complain about hub connection... now... it just blocks everything. Loathe to buy the range extender given its 1 corner of the house that has the problem and we are moving our boiler soon.2. Initial setup - I couldnt create an account without the app being connected to my hub... so as such I couldnt do that side of things before my hub was actually installedAll access is via the "app"... that is you have to have a phone/tablet to control the system with any granularity; there is no way to login online and make changes, even though you can control the system via the app when away from home.Only things missing IMO from the infrastructure are:- TRVs dont have a temp display on them (see honeywell).- a more advanced display control unit to upgrade to (see honeywell)- underfloor heating manifold (again...Honeywell) (we are planning this on our extension next year, so if not available will have to change systems, but for the price "right now" this is a no-brainer)- ability to login via a web-page and do all the same things the app can doSo far so good. Id **thoroughly** recommend and would buy again.

I bought the Drayton Wiser Multizone Kit 2 – Heating & Hot Water back in October. Six weeks have gone by so thought a review may help others if they are considering purchasing.My system consisted of a oil fired boiler that heated radiators all fitted with traditional Danfoss TRVs and a hot water tank that the boiler heated in the airing cupboard. This was controlled by a Drayton LP522 programmer and a traditional wired room stat in the hall.Installation was easy. The Wiser hub fitted onto my existing programmer wall plate. I decided I didn't want to get an electrician to bridge out the wired room stat as instructed. As if I didn't like the system I planned to return it.So I set existing wired room stat to maximum so that was always calling for heat and Wiser then would control my heat.Downloaded App, pressed set up button on hub but my phone would not find the Wiser wi fi. It turned out I was pressing button too long, its a sort quick press. Then connected no problem. Added Drayton wireless room stat, 2 Wiser TRVs to two radiators in Living Room also fitted Drayton smartplug/range extender which is not part of kit but purchased separately.All worked well and I bought two additional TRVs. So what happens is this enables you to control temperature through App and Alexa.Things you can do with Alexa.Alexa What is temperature in Living Room?Alexa set bedroom to 20 degreesAlexa turn on hot waterAlso use it to operate the Smart/plug to turn on power to a lamp plugged into it in hallNot all my radiators are fitted with Wiser TRVs. What this means is if a Drayton TRV or the Room stat calls for heat an old manual TRV will operate at the temperature it is set at. So for example Living Room Wiser TRV calls for heat, boiler fires and radiator heats. Kitchen Radiator if old manual TRV open then that radiator also heats.After about 4 days I ran into a problem. Devices (TRVs, Room Stat, and TRVs) all disconnected. So not visible in App. Switching off power to hub for 2 minutes eanbled them to connect again. But eventually they lost connection againTo cut a long story short I spoke to Drayton Customer services, they were able while I was on the phone to download data from my hub and diagnosed a very poor signal. Apparently the Smart Plugs/Range extenders are better at pushing out signal that accepting it from hub. So I ended up moving position of initial Smart Plug I had purchased and buying an additional 2 Smart Plugs. First Plug is 6 metres from Wiser Hub, second plug 11 metres from first and third placed upstairs.Now everything seems to be working perfectly.Easy to set up schedules in App so each room with a Wiser TRV can be controlled individually. There is also an Away setting that enables you to set a schedule or temperatures for when you are not at home. I use this for a frost setting. Of course you can monitor the temperature in your house wherever you are as long as your phone has a signalI really like system and the control it gives me. Integration with Alexa is great and a real benefit.As other have said in a large house signal seems poor and resulted in me buying 3 Smart Plugs in total. So maybe worth planning for this in case you have to go this route too.I will update this review if I have more to add in the future.It is 30/10/20, two years since I bought my Wiser system so I thought it was about time for an update.I'm still pleased with my purchase.I now have a total of 10 TRVs and 3 smart plugs (needed to extend range).Two things I have noticed...1 When away from home heating is off. I often use Wiser to turn on the heating before getting home. Normally works well, but if there has been a power outage at home while away, even a really short one I cannot use the App to turn the system on remotely.2 Last night TRVs were constantly operating motors. They were not operating heating but had lost connection to the hub. Looking at app this morning, devices not connected. I was on the phone to Drayton Support, they downloaded data from the hub. A smart plug which I used as a range extender had disconnected.I had great, patient support from the two Drayton customer support people I spoke to. Was an hour on the phone but the problem was sorted.As I said earlier, I am still pleased with the Wiser system.Things I like and how I use it......Increasing temperature in the room I'm in without moving of sofa "Alexa make the living room 21 degrees"Working in the garden, feeling I need a shower. Open door, call out "Alexa, turn on hot water", carry on working while the water heats.Turning on heat/water while away so house heated for return (see note about power cut above)I will continue to update my review as time goes by, but in summary the system continues to impress!

I bought this on a whim really as I was about to put my old Honeywell, wired, programmable thermostat and Siemens time switch back into my system following the fiasco with the Hive I had for less than 6 months! Noticed this Kit 2 as a warehouse deal "like new" so decided to give it a try.Very easy to install, with only 2 units - the combined boiler switch/hub/controller and the very small and neat wireless thermostat (the Hive had 3 units - the extra one required an Ethernet connection to your router).One installation hiccup was although all three boiler controllers state they will fit straight onto your existing, industry standard, back-plate in fact the Hive would NOT fit (it has a couple of extra profiles on the side of the box)so I had to fit Hives own mounting (not very good quality terminals). When I came to fit the Wiser controller it would NOT fit onto the Hive back-plate - it would have fitted the Siemens original one though! So I ended up changing the back-plate on both installs - at least the Wiser version has better quality terminals.A further problem arose when I was starting everything up on the phone app - it appeared the Hub was already registered to someone else - thanks Amazon! Strange as when I received the unit it seemed to be factory sealed,the batteries were shrink wrapped, protective film on screen ans even the clip in desk stand was included?At this point I let go a few expletives as I knew that with the Hive system, once the hub is registered to an account, it absolutely cannot be re-assigned - you have to buy a new hub for about £70!However I decided to ring Wiser support - not expecting much in view of my previous days call to Hive - nearly 2 hours long - 50% unintelligible audio, lots of resetting of my router, changing cables, standing on my head - all to no avail and when they said "advanced tech support would ring me within 72 hours" to sort it out I decided that was the taking the mickey - Screwfix refund beckoned!My call to Wiser support was totally different - a very helpful, polite, friendly and knowledgeable lady, whom I could easily understand on a clear phone line, just needed to know where the kit had been purchased and the serial number of the hub. Within 5 minutes the previous user had been cancelled and the hub was now registered to me - excellent stuff, exactly how customer support SHOULD work!Pros:Easy to fit / very neat small thermostat unit with the option of wall mount or desk mount / so far the app works well (the ONLY way to program a schedule) and has lots of options and information / attractive colour display / simple 3 touch button control to adjust room temperature or select boost feature / possible to control the system from the app if your internet connection goes down - just press the "setup" button once then connect your phone/tablet WiFi to the built in Wiserxxxxxxx access point.Cons:No Hot Water display on the thermostat (HW boost or over-ride ONLY available at the hub or on the app) / often the flame symbol stays illuminated for a long time after the room temperature is satisfied and the boiler has turned off (very slow update) / no proximity sensor to briefly turn the display on when you approach itOverall it seems a good workable system and if it proves reliable I might just shell out and fit the intelligent TRVs to all my radiators BUT, as I need 12 of these at a cost of around £480 I will have to be very sure of the reliability first - It would be nice to be able to schedule and temperature control various different rooms at varying times - almost like "zoning" without the extra plumbing and valves etc!Just a last word on my previous Hive - when the hub failed it also managed to corrupt the time setting in the thermostat and although they say "you can still run the schedule without internet", you probably could EXCEPT there is NO time setting function available in the menu so yes, it would run the schedule BUT about 8 hours out of sync with the actual time - useless!

We recently moved to a house with oil fired central heating, TRVs on the radiators - but no room thermostat! So one of my very first jobs was to remedy that, and while I was at it I thought I'd come bang up to date and put some sort of wifi connected smart system in. After looking at the popular ones that come to mind (Nest, Hive etc.) I stumbled across this Drayton system quite by accident. Having installed a drayton wireless programmable thermostat in our previous house to give greater control over the heating, and being pleased with it, I thought I would give this system a go. I bought the multizone 2 channel kit, giving me a hub that can control heating and hot water, a room thermostat,and two TRVs.I have to say, it got off to a very rocky start, and I nearly returned it. After installing it, which required me to use the supplied backplate as the existing honeywell programmer was not on a "standard" backplate, I paired everything up and installed the phone app, and quickly found it to be infuriating and cumbersome to use. Firing up the phone app sometimes opened it straight away, sometimes gave me several seconds (I mean 20-30) of "retrieving room info" or "looking for hub" before I could get in, and sometimes it just failed to find the hub at all and asked me if I'd changed my router settings recently? Several retries would eventually get me in.I had several protracted email conversations with the support desk (I didn't even attempt phoning). I must say they generally responded within a day, and were helpful and managed to resolve the many problems I encountered. Apparently the initial sluggish app behaviour was due to my account not having been paired up with my hardware properly, not uncommon from what I've seen. Then I had a few more one-off instances of odd behaviour, and the room thermostat, after working in the place I wanted it for 2 days, then started losing connectivity to the hub due to poor signal and I had to move it temporarily.The hub talks to your wifi, and it seems to be able to pick up a decent signal on ours, but the devices communicate with the hub directly, not via the wifi, and these signals seem to be very weak. After some protracted further email conversations with support, during which they tried to get me to buy a range extender from Amazon (£40 and not even available on there yet), they eventually sent me one free, and this does seem to have resolved the last of my problems. I was on the verge of packing it all up and sending back, but after a month of teething problems, it is all now working reliably, and for the money compared to other similar systems, I would say it is pretty good.Another major problem I had which lasted a couple of weeks was using the Amazon Echo to control it. After working perfectly to start with, it then started failing to respond to certain commands (what is the temperature in the lounge?). This also took a while to resolve with support, and I was told eventually turned out to be a problem at the Amazon end, nothing to do with this system. It is all now working.But it only came out a few months ago, and to me it still feels like it is at the advanced prototype stage, rather than a fully debugged reliable system.The only remaining gripe I have with it now is, if one of the TRVs has called for heat, and then that room has reached temperature and the heating shuts off again, that TRV continues to emit a short "groan" at precise one minute intervals for the next 20 minutes or so, which could be a problem if this happens in a bedroom just as you go to bed. I am told this will be addressed in a firmware upgrade soon.Knowing what I do now, I'd buy it again, but you may be in for some teething problems so be prepared for that.

I am at home most of the day and need to have some rooms heated but not all of them. I live in an old house that is expensive to heat and hard to insulate. Having done what could be done, I wanted to save further on fuel and began looking at the rooms that were empty all day but were still being heated because the heating was on. The Drayton Wiser system appealed to me because I can set schedules for every room that would benefit and only heat them when they needed to be heated. It was fairly easy to install: my radiators had non-standard TRVs (Thermostatic Radiator Valves) and the smart TRVs would not find and neither would any of the adapters.In the end I drained down my system and swapped the TRVs for some very cheap ones from Toolstation that were compatible with the new smart TRVs, and then I could easily fit the smart TRVs where I needed them. I did the wiring myself - that was trivial.My house is very spread out being a chalet bungalow and I found two of the smart TRVs were about on the limit of the range from the Wiser Hub, so I bought two Wiser Smart Plugs - these are very expensive compared with other Smart Plugs that I use but they also function as an amplifier for the Wiser Hub ensuring that those two zones always get a good signal.I'm not going to write here about all of the benefits of a smart system - if you're looking for a smart system then you'll already know most of those from their advertisements. I looked at several systems including Hive and Nest and felt that the Drayton Wiser system offered the best value for me because of the ease of setting up zones. It has all of the features of the others apart from Nest's ability to not have schedules instead opting to learn what you want by observing how and when you set your heating.Drayton not only had the best match of features for me, but it was the best price, and Drayton have been making heating control systems for donkey's years - they are a household name for heating.The app has some very interesting statistics (graphs) to show you how your heating is performing. It has intelligent modes that can shut off the heating for a room if there's a window open there. It works well with Alexa. With the help of Life360 and IFTTT it is easy to set up geofencing so that if nobody is home it goes into background heating mode and then automatically resumes the schedule when someone arrives back home again.Now on to why I only gave 4 stars when what I've written suggests 5 stars...[a] If there's a power cut, or the internet drops out, then often the hub gets "stuck" and cannot reconnect to the Wiser cloud - it sits there with a red light on. My son-in-law has the same system and also experiences this issue. The heating still continues to work, but you can't work it or monitor it remotely. The fix for this is to turn off the master switch for the heating, thereby shutting down the hub for 2-3 minutes and then turn it on again - but you need to be at home to do that UNLESS: I fitted a smart plug in the power feed to the Wiser hub so (remotely) I can cycle the power on and off. Fortunately, we don't get many internet outages or power cuts.[b] It's quite an investment in time to set up all of the schedules and I change them with the seasons [1] Spring and Autumn, [2] Summer and [3] Winter - I have requested (but had no feedback) that it ought to be simple to have the App store your schedules as a SET so that you could restore each SET as and when you need it.Bottom line: brilliant system but nobody's perfect.

This is really good system and installed in a 1930s bungalow with 13 radiators. Mistakes I made on the first install:Trying to be clever and keep things tidy I initially installed the base unit very near the boiler. This was a mistake as you should put it in as central location as possible in order for it to see your router/TRVs. (and preferably away from large metal white goods that are going to interfere with signals).Naively I assumed that the new smart TRV(thermostatic Radiator Valves) would be compatible with the old lockshield(tap) valve controls. You require compatible thermostatic Radiator valves and I had to install 4 new ones for the planned system.(cheap units are available for around £7 each - and you don’t seem to be able to buy just the valve body). These require the system to be drained and a bit of plumbing work.Good pointsWhile it takes a while to get used to the philosophy behind the new control, its great being able to switch individual radiators off. We have noticed that the system heats up so much faster and each radiator gets hotter.I’ve found the app very intuitive and relatively clear.The integration with Alexa is seamless and brilliant.The thermostat is very accurate and the TRVs accurate enough.You have the option for the system to switch on at fixed times (normal mode) or to be clever and use ambient temperature to determine start times (comfort mode)Bad points.Sometimes it takes a while for the boiler to be requested to fire despite the indication of Flame ON displayed on the app.An indication of the position/status of each TRV would be useful.It would be nice if the thermostat was non-backlit LCD with the display on all the time rather than having to wake it up to display the current temperature. I also assume that only the thermostat temperature is used in its assigned room rather than the associated rooms TRV – does the system just ignore the TRV temp?. (I also wonder if you can have a cheaper system without the thermostat as I’m not sure it adds much.)Things that still confuse:The app has too many ways to change room temperature. E.g• There is a boost function which has a time limit. (also enabled from the TRVs control). Does enabling from one radiator automatically apply the same boost to others assigned to the same room?• You can also change the room temperature without the boost time limit.• You can also set the room to MANUAL (shown as a HAND on the app) control.I’m still unsure if ALL or any of these settings are automatically overridden by a scheduled temperature change?Word of warning for those with an older system. I had planned to smart control just 4 of 13 radiators in rooms only used part time. I did this but noticed how much warmer the whole house was. The problem being that 6 radiators/towel rails in my house do not have TRVs (just lockshield taps). The living areas would get up to temperature with bedrooms ‘smart controlled’ off, then prior to bed these would switch on but request the boiler ON for prolong periods to get them up to temperature. However, obviously the 6 radiators/towel rail with lockshield valves would then get very hot in rooms already up to temperature. So I’m now having to convert these to TRVs or smart. In summary – your house requires TRVs!This is a very good system and I’m not entirely sure what features are missing or that you’d ever need. Only concern is the longevity of the motorised TRVs at £40 a pop.

I bought the Drayton Wiser Multizone Kit 2 – Heating & Hot Water back in October. Six weeks have gone by so thought a review may help others if they are considering purchasing.My system consisted of a oil fired boiler that heated radiators all fitted with traditional Danfoss TRVs and a hot water tank that the boiler heated in the airing cupboard. This was controlled by a Drayton LP522 programmer and a traditional wired room stat in the hall.Installation was easy. The Wiser hub fitted onto my existing programmer wall plate. I decided I didn't want to get an electrician to bridge out the wired room stat as instructed. As if I didn't like the system I planned to return it.So I set existing wired room stat to maximum so that was always calling for heat and Wiser then would control my heat.Downloaded App, pressed set up button on hub but my phone would not find the Wiser wi fi. It turned out I was pressing button too long, its a sort quick press. Then connected no problem. Added Drayton wireless room stat, 2 Wiser TRVs to two radiators in Living Room also fitted Drayton smartplug/range extender which is not part of kit but purchased separately.All worked well and I bought two additional TRVs. So what happens is this enables you to control temperature through App and Alexa.Things you can do with Alexa.Alexa What is temperature in Living Room?Alexa set bedroom to 20 degreesAlexa turn on hot waterAlso use it to operate the Smart/plug to turn on power to a lamp plugged into it in hallNot all my radiators are fitted with Wiser TRVs. What this means is if a Drayton TRV or the Room stat calls for heat an old manual TRV will operate at the temperature it is set at. So for example Living Room Wiser TRV calls for heat, boiler fires and radiator heats. Kitchen Radiator if old manual TRV open then that radiator also heats.After about 4 days I ran into a problem. Devices (TRVs, Room Stat, and TRVs) all disconnected. So not visible in App. Switching off power to hub for 2 minutes eanbled them to connect again. But eventually they lost connection againTo cut a long story short I spoke to Drayton Customer services, they were able while I was on the phone to download data from my hub and diagnosed a very poor signal. Apparently the Smart Plugs/Range extenders are better at pushing out signal that accepting it from hub. So I ended up moving position of initial Smart Plug I had purchased and buying an additional 2 Smart Plugs. First Plug is 6 metres from Wiser Hub, second plug 11 metres from first and third placed upstairs.Now everything seems to be working perfectly.Easy to set up schedules in App so each room with a Wiser TRV can be controlled individually. There is also an Away setting that enables you to set a schedule or temperatures for when you are not at home. I use this for a frost setting. Of course you can monitor the temperature in your house wherever you are as long as your phone has a signalI really like system and the control it gives me. Integration with Alexa is great and a real benefit.As other have said in a large house signal seems poor and resulted in me buying 3 Smart Plugs in total. So maybe worth planning for this in case you have to go this route too.I will update this review if I have more to add in the future.

I have just had Gas central heating installed and I was looking to make the Gas Central heating smart. It took weeks of looking into it and many different products...In the end I went with Drayton Wiser because of the reviews and the supposed flawless ability to control every radiator individually. Well I am pleased to say i am glad I went with this product.. Friends of mine have different systems and they do not have the control that i have...The plumber fitting the central heating system insisting this system will not pull water from the boiler directly it will have to go to the main thermostat first...I said to him we will agree to disagree...The next day he told me that his fellow tradesmaenhad stated the main thermostat will control the radiators..I again said we will agree to disagree...Well it was me that was correct and left the gas engineer Gob smacked. I have eight radiators and the radiator in the hall is the open all the time radiator as a fail safe so if you are pulling water to any other radiator you will get this radiator on as well so fit that one without any smart TRV into the hallway as this is usually the coldest room and the wall thermostat will control that one only....The other seven radiators all have Drayton Smart TRV's and I have total control....I give you an example...If i want just the kitchen to heat up I can...The smart phone app is brilliant showing a list of all my rooms with the radiators...lets say i changed the temperature for the kitchen radiator from say 18C to 24C and the app will show a flame telling you the radiator is powering up and calling water and around ten to thirty seconds you hear the smart TRV on the selected radiator make a little noise as it opens the valve then the boiler fires up and about ten seconds later the radiator starts to get hot.All the other smart controlled radiators are still off because they are not requiring heat. You can then set the scheduling for any time for each radiator to come on and off and at what temperature....complete control...Example the kitchen may be set to 21C and the Lounge at 23C while the bedrooms are off...that is until later if you so wish...This is total control and I cannot believe how good it is. I have the room where my cats are on most of the time but the rest of the system is just set to frost protection until i need them on and they fire up on the time I have requested....Lets say the scheduling is due in an hour but its cold instead of changing the scheduling just set a thirty minute one hour or three hour boost to whatever radiator you want. Its total control and it is already saving me money....Two other settings of interest...a COMFORT setting brings whichever radiator you want on earlier than the scheduled time so the comfort temperature is there when you want it...I don't use this because I think it would use more gas..I do use however the ECO mode, well this setting monitors the weather outside and how quickly your house heats up and cools down and assists in saving you money......This is an excellent product easy to install and operate, eventually your schedule will run the house without you having to do anything.....My cats love it...Highly recommended

Bought the two sets of the multizone (heating+water) controls on the recommendation of my plumber, so two room thermostats and 4 TRVs, plus a spare Hub. Written after 4 months of use though winter:Pros:- Easy enough to install and add new components.- The Wifi range of the Hub is weak, but adequate in a thick-walled brick house as long as the hub is central, otherwise you'll likely need some range extenders.- The app works well whilst on WiFi and still seems to be getting improved. The boost function is great, adding a couple of degrees heating to a room.- The app heating reports are very useful in seeing which parts of the house need more attention with regards to draughtproofing or insulation,or simply more heating- Hot water schedule has been great, and very easy to give it a quick boost if needed.- It occasionally fully opens and closes the TRVs around the house so they don't get stuck through lack of use. The TRV motion is audible, but not overly loud.- The granular control over the heating times and zones has halved my gas bill, recouping the cost of the system in just 2-3 months.Cons:- Rooms occasionally heat up or cool down randomly, rather than following their set schedule. Drayton Wiser support offered no explanation so my solution to this was to add more identical time points throughout the day, so they check every couple of hours and hopefully reset themselves accordingly. Seems to work.- One of the TRVs has failed already, locked in the open position so an unused room was being heated towards 30 degrees - only noticed as the gas smart meter buzzed a budget alarm. Drayton Wiser support tells me this is not their problem, so doesn't come under any sort of warranty. Thankfully Amazon exchanged it without question.- Connecting to the hub remotely whilst out and about is very slow. Support tells me this is my phones fault and the home wifi networks fault despite all the other smart devices in the home being absolutely fine remotely.- Support is patient with simple queries but do ignore any support tickets they don't want to answer.- The Alexa integration is a bit hit and miss. Asking for current temperature or extra heat works perfectly, using a simple routine to turn the heat off in a single room inexplicably sets the whole house to boost mode.Suggestions:- Set up a dedicated 2.4GHz SSID for your heating. Should be possible in your router settings.- Let the hub update automatically to the latest firmware. There's nowhere online that will tell you what that might be or what the changes are, and if it fails (due to network congestion or whatever) it gives up so it's worth checking with support that it's reached the latest version. They can also remotely restart the upgrade process if necessary.- The warranty with Drayton appears worthless as they won't accept that parts might fail. Buy it from a retailer that has a decent returns policy.Despite all that I do like the control aspect and it is saving a lot of money, but do wonder if I might have had a better overall experience with another manufacturer.

I bought this after getting fed up with going to bed cold and waking up roasting. My thermostat was in the hall so even with thermostatic valves the other rooms were never the proper temperature. The bedroom was especially bad. I could never get it comfortable at bed time, always chilly, and then in the morning too hot as the heating tried to get the ground floor warm. I looked at several other products, HIVE seems good but the basic kit just replaces the thermostat and I wanted more. TADO seemed to fit the bill but seemed expensive.This system has sorted this. I put the two radiator valves in the living room and bedroom. The bedroom is now comfortable when I go to bed, kept at a constant temperature all night,but doesn't get too hot as the rest of the house is warmed for the day. The living room is warm when I get up and stays warm till bed time. The bedroom is no longer heated through the day, but If I want a daytime bath I can warm it for changing from my app, or just a quick twist on the radiator cap will again add heat.I haven't enabled goe-location, but I have put buttons on my phone that I can use to turn "away mode" on and off as required, so hopefully saving money.So all in all its doing what I wanted, and I am very pleased. I have only given four stars as I think the Alexa and Google integrations are a bit limited.I would also say installation can be a pain. If you have a conventional (non-combi) system with a Y-valve or two motorised valves, a programmer on a standard wall plate and fairly modern Thermostatic Radiator Valves (TRVs), or a combi boiler and modern TRVs then you are pretty much good to go.Saldy I had a single motorized valve, old TRVs that are too small to fit the new Wiser radiator valves and a programmer on a non-standard mounting plate. So the install was a bit of a pain. The existing boiler circuit required a tweak as it was wired so that the system only ran if just the "Hot Water" input was live. The existing timer was not on a standard plate so some drilling was needed to fix the new plaate. Also when it says "by-pass the thermostat" you usually need to add a link to do this. The instructions are not clear at this point.I ended up replacing several radiator valves. One TRV was stuck and leaked when I operated it a few times. One lockshield (so the trailing valve) developed a dribble, one radiator (the one where the thermostat was) didn't have a TRV, and one TRV was the wrong size and Drayton didn't make an adaptor, which is odd as it was a drayton valve. In any case the new radiator valve was cheaper than many of the adaptors, but as draining the system is a pain if one valve needs replacing check them all.I don't think this will be typical. My basic heating system is 38 years old, and its a tribute to the Drayton folks this works with it.Once the physical install was complete the app set up fine and it connected to my router no probem. All working fine.

Where to start. Well swapping over the controllers was an absolute doddle, and the smart room thermostat did all the work itself. It all seemed so simple. And then the problem hit. Trying to connect the controller / hub to my WiFi. So many times it said it connected but then the app couldn't find it, red lights flashing, green lights flashing. It nearly went back in the box and to the UPS returns point. However I swapped some emails with Drayton Support and they suggested I try a different phone to the Huawei P30 I had been using. I tried an old Samsung S7. This time during the connection the setup light went solid red so I contemplated an unopened bottle of whisky. As I contemplated for about 10 minutes,the light went solid green. The app still wouldn't connect. I had set the guest wifi to 2.4GHz having previous experience of smart things. Eventually in despair with thoughts of a hefty hammer I changed the 2.4 GHz WiFi back to 2.4 GHz / 5 GHz auto. Closed the app, restarted. At first it still refused to register / find the hub. And then a miracle - it found the hub after a few tries. It all works now. Only 6 hours later.So the secret to not spending 6 hours. Set your guest WiFi to 2.4 GHz. Run through the connection routine as far as the register page and remote control. At this stage you are directly connected to the hub on a temporary network. On your phone "forget" the passwords to your home WiFi networks or your phone may switch networks when it shouldn't. At the end of setup, tell the hub the name and password of your guest WiFi. It should turn solid red. Make sure the hub setup light changes to solid green - can take 10 minutes. At that point, change your Guest WiFi back to 2.4 GHz / 5 GHz auto. Give it a few minutes to settle. Connect your phone to the guest WiFi. Complete the registration and click to remote connect. You may need to try a couple of times. If not return to the register screen, skip, logout, restart the app, try again. Perseverance seems to be required. Put your hammer and bottle of spirits away, relax with a nice cup of tea. You can now reconnect to your main WiFi and test whether the hub can be controlled from a different WiFi. Test with mobile WiFi too. Drayton support come back quickly if you need them but hopefully my experience will help you complete the process a lot quicker.Once set up you can control both central heating and hot water remotely from your phone. On that basis I would give the product 5 stars but the setup instructions only 2 because whilst it is easy when you know what to do someone needs to tell you how when it doesn't work first time. Switching WiFi networks around a couple of times - not in the manual, not intuitive unless you've gone through the pain before. Changing phones - never would have thought of that. Drayton support were good, 4 stars. So overall a 4 I think.

Started off with just the Drayton Wiser Multizone Kit 2 which controls hot water and central heating along with one zone thermostat and decided to buy a 3 radiator thermostats after installing the kit. Since then I have bought a further 11 radiator thermostats so every radiator in the house is now controlled independently which is such a bonus, to give you an idea of what I mean my daughter gets up at 6:20 AM so her radiator comes on at 6:15 AM and her bathroom radiator comes on at 6:20 AM so the rooms are warm as she needs them. likewise our bedroom radiator comes on at 6:45 AM and our ensuite at 6:50 AM and 30 minutes later when we dressed and ready the hallways come on and the kitchen fiveminutes after that just as the bedroom radiators are turning themselves off.I know it's costly having each radiator independent with thermostat and they are cheaper if you look around but the flexibility it gives you is unavailable, like someone's said before takes 10 minutes to install the control panel which is just to screws into the back plate and then download the app for your phone and register the system, each radiator valve takes no longer than five minutes to install only time-consuming part of the insulation is setting up each radiator on the app for which times you want it to switch on and off and what heat you want it set at.The only slight negative is our route is in the far corner of our house and does reach all the radiator valves but on the top floor it's only one bar reception so I have bought a cheap Wi-Fi booster for 15 quid which now put them all on four bars out of five.I'm in the building trade and have seen the hive system installed by plumbers on jobs I've worked on and decided to go for the Drayton wiser system as I could fit it myself to the existing system and now in hindsight I would of still choosing it over hive due to its flexibility, control and ease of installation which any one that can download app and tighten up to screws can do.PS keep all your old radiator valves and thermostat control box has when you move home you can put them back on and take this system with you and fit it to your new property if needed. Will save you hundreds of pounds in buying new equipment along with I feel a considerable amount of money by having heating on only when you need it.Update after a month of use. Still really impressed with the system couple bugs which are annoying firstly they have updated the app which is a lot better but still very temperamental.Secondly it's dropped a teo of radiators due to my poor wifi signal but resolved it by getting a cheap Wi-Fi booster and quite easy to reset them just a case of turning the valve to right side for about 20 seconds to it flashes red eight times and then just go through the normal set up procedure again and has been fine since.
