I was tracking this as wanted to buy it for my new house. It was £316 which was normal price. Best all time was £273 which honestly was a great price and was waiting for it. Instead it dropped to an all new best.

For those unaware, it's probably the best smart TRV system in available in the UK atm. Honeywell Evohome is the only direct competitor, and it's visually outdated, plus it's way more expensive without providing anything else.
Drayton is British made, from Schneider Electric.

Don't compare it to systems like Tado, Tuya and the like. All those run on WiFi and the cloud, while Drayton runs on its own network, Zigbee. The main difference is that can still work if you lose access to the internet, plus the speed of response is way over WiFi, where it's common to wait 2-5 seconds for a reaction.

If you don't need 5 TRVs, you can also get the basic Kit with 2 TRVs which dropped to a great price too: smile.amazon.co.uk/dp/…ZQ1

Edit: expired sooner since deal units have been sold. There is still the 2-channel kit with a discount.

    So, after installing this and using a couple of days, here are some annoyances:

    1) Only one account per system. You have to share you password and username with the other people who want to control the system.
    2) Plastic screw-in adapters. The old TRV4s that this replaces had some serrations where they met the valve, so if you screw them tightly they can't rotate when changing the setting. The bottom side of the adapter has these serrations, but it's pointless because the controller body itself can rotate against the adapter thread at the top. I don't know how I solve this, maybe some thread locking compound? This wouldn't matter so much if they just added simple buttons for + and - at the top but instead they had this stupid idea to mimic the rotation of the manual thermostatic valves, so you twist against a spring to change the heat setting for the room, and it springs back to center. Twisting too hard in the - (minus) direction you are unscrewing the body. This is probably the most irritating aspect of the system.
    3) It's a shame that the hub itself doesn't seem to have a temperature sensor. It would have been nice to have it in place of a room thermostat and save a fair bit of money on an extra battery operated thermostat.
    4) Not sure what I did but I did manage to lose all my pairings at some point when I got locked out of the hub access point. I had to start from scratch when I hit the setup button again. It would have been nice if it remembered what I did before and allowed me to just change one part. I think this was my fault because I didn't get the hub connected to my wifi network first time round and assumed I'd be able to talk to it from the app indefinitely when I'd installed the system as a plumber instead of as a home user. I re-installed as a home user and things worked better.
    5) Factory-reset of devices so they can be re-paired is a bit long-winded.
    6) It would have been nice to have a schedule for the house, then setup what/how rooms deviate from that. Instead they are all individual. You copy-paste a schedule for one day to other days for a room. You can then copy the entire room schedule to other rooms. I would have preferred some concept of mon-fri setting and a w/e setting but they are just individual days and need to be programmed individually. A web interface would have made this process so much more comfortable. I really hate this modern trend for only providing an app.
    7 ) There is no kill switch for the boiler (that I could find). I wanted to just switch it off when everyone had gone to bed, but I had to adjust all the rooms away from the schedule.

    I may change my opinion about the above once I get to know the system better. I still like the price, and this mostly does what I want, so I don't regret the purchase (at least at this price). (edited)

    Here are my gripes.
    1) Geofencing ridiculous and doesn't work.
    2) setup was OK, but twice the hub disconnected from mesh for no reason.
    3) two trvs did not want to connect
    4) one room is freezing (apparently it is the only room that has the trv on the return and not on the flow). The trv is biderectional. Apparently Drayton does not support trv being on return as it messes up their algorithm.
    5) moments are useless. They only alter for a moment and do not have a duration. I wanted to use them to ovveride schedules on studies when sometimes we do not work from home but we are working from the office.
    6) their eco prediction is useless
    7) the last straw. I woke up yesterday and the house was freezing. All trvs called for heat but didn't actuate and turned on the valve. Called support immediately. They said disable eco and they would look into it. They said oh but we don't get good signal from two trvs and. I said none opened etc. Oh change batteries. I said it is only 7 days old the system. They said oh maybe you don't have the right adapters. I told them which ones I have. Then they said reset and recalibrate each valve. I did. And they said they would look into it with tech support.

    Put them on again. Woke up again today, house freezing. Same story. All called for heat. None opened. Emailed them. Called them. No reply.

    That was the last straw.
    Yes is cheaper from tado (and has some features eg opentherm, zigbee valves) but it is unreliable.
    It is going back on the weekend and I am installing tado.

    Does this have geofencing and open window detection on the TRV's?
  3. ALW_'s avatar
    Can anyone recommend any reputable retailers selling the smart TRVs to extend the system? The amazon Drayton shop only sells the kits with black Friday prices. I would need at least 3 more TRVs on top of the 5 with the bundle. Thank you so much

    City plumbing. £35 single thermostat atm. Can't remember about the kit. Plugs are also discounted.

    Second best is toolstation £38 each atm.

    Yeah I also need 1 extra and I'm waiting to see if there's any other drop. (edited)

    Don't know how to add to this post but there is a separate post for additional TRV's @ City Plumbing for £35.99 each

    Is the instalaion required only the replacement of the thermostat and not the main control which I assume you put to constant? And can you have two thermostats for two zones? Appologies for being lasy and not following down a google hole!
    ClubLife's avatar
    After a lovely chat with their technical team, I was sold on this system and have ordered one.

    He confirmed that you can pair up to 4 TRV's per thermostat, if you want the thermostat to be the main detection of temperature in a space i.e. oddly shaped/long rooms.

    You have to install the controller hub in all instances, this replaces your programmer usually situated under/near you boiler, this is the brain and stores your schedule and communicates with the smart TRV's to open/close the pin and allow water through the valve, or not.

    You don't have to have a thermostat in rooms, as the TRV's all have a built in thermostat built in. However, their engineer admitted honestly that the TRV's have an algorithm built in which allows for a 2.5°C variation from the true temperature, so if your TRV is going to be situated behind a sofa or furniture, he suggested implementing the/a smart thermostat on the wall in that room to determine a truer temperature.

    I apologise in advance as this is a bit irrelevant to this deal but seeing as energy prices have gone through the roof and everyone looking to save a bit of money using up to date tech.
    Long story short my gas annual usage was really high so I started looking into it to figure out why. Conclusion I got to was that my thermostat was just on/off and not modulating one so boiler would run at full speed until room temperature was achieved and off. I decided I wanted modulating thermostat of which there are many in the market. I have vaillant boiler and I found out vaillant do not support third part thermostats for modulation. All these expensive internet controlled thermostats are only as good as £30 digital on/off thermostats. So anyone who owns vaillant or worster bosch boiler, unfortunately all third party thermostats are costing you more money then they should.
    In 2018 government brought in new regulations so all new combi boiler installations had load or weather compensation devices controlling them. Unfortunately they left the loophole so if you had smart thermostat your installation will still comply with new regulations but that means in reality your system will be operating like old school tech with at least 2 mentioned brands. Both brands do not support open therm technology (or at least not that I'm aware of).
    Please do your own research but I thought I'll give you food for thought as most plumbers are unaware of this too. (edited)
    Joe_Bifferos's avatar
    This is an interesting topic of discussion. Just checked my Vaillant and it doesn't support OpenTherm either, but you can buy a module... search for "Vaillant VR33 OpenTherm module 0020017895 for Vaillant boilers", but I won't rush out to buy it just yet methinks.

    would this work with a nest system?
    Chaoscontrol's avatar
    Chaoscontrol Author
    No, Nest doesn't have multi-zone capabilities. So the TRVs alone won't work with it. But this system just replaces Nest entirely.
  8. Joe_Bifferos's avatar
    Note that you get the items as two deliveries, first the thermostat, heat hub (probably) and two thermostats, then another delivery more than a week later with the additional thermostats. At least that's what it says when I try to order. That may be OK with you, you can get the system up and running with the two TRVs then add the others later when they arrive.

    The other thing is that on the checkout screen (after you click buy now) it makes no mention of the Heat hubR. In fact they are a bit annoying about this, because it's in the description, but there's no picture of it. Except when you mouse-over the video it shows it albeit not very clearly. And in other black friday deals they refer just to 'room thermostat' and again it's ever so slightly ambiguous whether this includes the hubR. It would be nice if they just put a picture of it so we know exactly what we're getting.

    Just found a video that explains this fairly well (with a timecode so you can skip to the important bit).

    It includes the controller hub, I double-checked that this was included in the starter kit directly with Drayton's tech team.

    i bought this but can anyone please advise? my boiler is constantly on. within the app nothing is set to tell it to heat up and all TRVs are set to off, i have no schedules listed but the only way to stop it is to literally turn off the power? (edited)
    simes's avatar
    Is the heating light lit on the hub ? If its not then its a wiring issue as the wiser has not switched on the boiler..
    If the light is on then give the support line a ring . They answer quickly and are really helpful .. Bear in mind the wiser will sometimes call for heat even if all thermostats are at the set temperature . This is to ensure you rooms stay at the set temperature (instead of cooling then re-heating).
    They will probably tell you to set up schedules though - why would you be trying to run it without ? . You can't actually turn TRV's to off - they are set to a temperature ( setting it to the minimum - which i think is about 6 degrees would keep it closed). (edited)
  11. Mentos's avatar
    Are you sure you haven’t wired the “call for heat” wire to the “off” pin on the wiser panel? On the 2 ch panel:

    N =.  Neutral. (Usually Blue)
    L =.  Live. (Usuall Brown)
    Pin 1 =  HW off
    Pin 2 =.  CH off
    Pin 3 =.  HW On
    Pin 4 =.  CH On

    If you’ve put Live in Pin 3/4, then HW/CH would always be on as that Pin would always be Live, telling the boiler to fire.

    If you’ve put the call for heat/water wire (check from your previous programmer, if you still have a pic of the wiring) in PIN 1/2, then HW/CH would be on when it’s supposed to be off.

    If you’re boiler keeps running, I suspect you’ve done one of the above.

    If the status light isn’t on in the hub, then you’ve probably put Live in 3 or 4.

    If the status light is on, then you’ve probably put call for CH/HW in pin 1 or 2. (edited)

    OP, you may want to correct the following form the deal description as its innacurate:

    Don't compare it to systems like Tado, Tuya and the like. All those run on WiFi and the cloud, while Drayton runs on its own network, Zigbee. The main difference is that can still work if you lose access to the internet, plus the speed of response is way over WiFi, where it's common to wait 2-5 seconds for a reaction

    Tado doesn't use WiFi, it uses 6LoWPAN (868 Mhz), which is similar in principle to Zigbee. In fact i'd be surprised if any similar product uses WiFi, as in this sort of application power efficiency and resilient connectivity are more important then bandwidth and latency.

    You may be getting confused with complaints about Tado hosting the schedules in the cloud, which is one of the downsides. If you lose internet connectivity, there is no local schedule with Tado unless you use HomeKit.

    The other issue with Tado is there are no repeaters/extenders, you can only have one bridge and all the TRV's/Stats need to be within wireless range of that. They've been suggesting both these issues are high up on their development list, but to date neither has been addressed.

    I'm unsure if Drayton offers repeaters/extenders? Zigbee nodes can operate as a mesh, but its unlikely the TRV's would do that as they are battery operated, usually its mains powered nodes that will form a mesh to extend range whilst battery powered nodes simply connect to the strongest signal from any node in the mesh. As an example, Hue mains lights (which also use Zigbee) form a mesh and act as repeaters, but I believe the battery powered sensors do not. (edited)

    Ah my bad. I knew it was something like that. Thanks.

    Yeah Drayton smart plugs are Zigbee routers. Although I guess being Zigbee any router can be used, or that's what I'm hoping.

    TRVs are not, as you say, since they're battery powered.

    So much so that I'm moving within 6 months or so, so I may as well buy this.

  15. Burgmeister's avatar
    With hindsight I would have got Drayton kit but went with hive when it was on offer. I believe that hive also works with ZigBee and the only problem with that is that the range isn't great. I had to move the various system components around as they kept dropping connection in their original locations

    Its the starter pack with 2 TRV, plus a 3pack of TRV. I just ordered and it's all for 230
  17. IndianaBlues's avatar
    A couple of years ago they had the starter pack with 2 TRVs for £85 over Black Friday, so glad I bit the bullet then - bought 2 of them plus an extra TRV then sold the additional controller and thermostat on ebay... but the system itself is great, can't fault it

    Chaoscontrol's avatar
    Chaoscontrol Author
    It's recommended to leave at least one in your house without TRV, so it's always open. Suggested the bathroom, as it's small.
    Aside from that, any radiators to create the zones you want. I'll be installing 6, leaving radiator and hall without any.
  21. discobob's avatar
    If you have Intergas (maybe others) and Cylinder you can use the single channel - just set up the Hot Water on the boiler for Timed or on demand.

    Two channel and more models the OpenTherm doesn't work (yet) on them

    I need two Smart Room Thermostats one for upstairs and one for downstairs. Now I just need a good price for the second unit.
    Chaoscontrol's avatar
    Chaoscontrol Author
    Why? The point of this is to have the thermostats on the radiators. Actually I was even considering not getting a room thermostat, as it is fairly useless with this system.
  23. finknottle's avatar
    Believe I got the kit with two TRVs for £90-ish on BF last year, from Amazon. I know, time machine etc., but has the price gone up massively since then, or was that just an exceptional deal?

    (Side note, still haven’t installed the thing - does anyone know what if any adaptors I need to get it working with a Worcester-Bosch Greenstar 28i please? ) (edited)
  24. sc03tye's avatar
    Usually parted with the cash by now… not convinced this would really save money in our case if I could have opinions?

    Got Nest, can’t say it’s programmed at all and we use it manually for heat when it feels chilly.

    Small 2/3 bed end terrace, 2-storey.

    Neither of us living here work to specific routines I.e we could be upstairs or downstairs during the day or out completely. Again, if cold we just turn the Nest up until the boiler turns on.

    In the evening we’ll more than likely both be downstairs for a few hours, heating on, and head upstairs after into the warm rooms same as downstairs, based on their manually set them stat levels.

    Is it just that when you have an east and west wing with large open areas that these actually help out? Thinking as it’s a small house that the heat just gets about anyway.
    Chaoscontrol's avatar
    Chaoscontrol Author
    Can't say about amount of savings. But our house is the same, 2 bed end terrace. We spent most of the day in the lounge, so upstairs don't need heating during the day at all I think. Obviously some heat will leak there, but when we close the lounge door you can really feel the temp difference when leaving.

    So heating the lounge only vs heating the entire house has to make a difference. Plus having thermostats everywhere makes the boiler heat only where it's needed. Plus all the smart functions, but that's depending on what you want to do obv.

    is this better than Hive ones?
    Chaoscontrol's avatar
    Chaoscontrol Author
    No clue tbh. Didn't even know Hive offered something similar. Haven't heard them recommended tho.
    I checked and they run on Zigbee, so that's good at least. Not sure about all the other features.

  28. leet's avatar
    Sorry I'm confused. So are these smart thermostats? If so where's the bit I wire into the combi boiler?
    meridiusuk's avatar
    It comes with a wireless controller box as well which gets wired into the boiler.

    Included in this kit is 1 x Smart Room Thermostat, 1 x Heat Hub
  29. meridiusuk's avatar
    Noticed this has Weather Adjustment What is that exactly
    Chaoscontrol's avatar
    Chaoscontrol Author
    I believe it's a function that has weather integration, so when you're heating and it knows the outside temp is higher, will stop the heating pre-emptively knowing you won't need it to reach the set temp. Or something like that.
  30. u664541's avatar
    Great deal.
    Installed Wiser system last January. Not gone down the route of TRVs yet but can see the advantages of them (upstairs bedrooms not needing heat during the day for instance).
    Even without the TRVs it’s saved me £ over the previous “dumb” system. App is easy to use and whilst I’ve not needed to use them the Wiser support is meant to be top notch.
  31. ans91's avatar
    I want to replace my existing Hive 2-zone system with this, does anyone now if I can replace it with this? My existing Hive system has 2 receivers (one controls downstairs heating and hot water and the other one controls just the upstairs heating).

    From reading the description it seems the heat hub is 2-channel so this wouldn't work? And even then if I could get it to work, I would have to somehow combine the wiring from the 2 receivers to the one unit heat hub?

    FYI there's a 3 channel kit too. Not sure if that works for your case though, as I'm not expert enough.
  32. leet's avatar
    My kit has arrived but the thermostats don'e fit on my radiators? Am I screwed now or is there a way around it?
    ALW_'s avatar
    Drayton will have adapters if you are replacing existing manually operated TRVs
  33. Mentos's avatar
    They've got the 2 channel (if you have hot water tank) for £6 more.

    Torn between this and Tado. Want the smart geofencing (will pickup an old bridge to get it for free if I go Tado) as I have it with Nest and it works really well with our erratic popping in and out of the house. Also like the temp display on the Tado TRV's and aesthetically they look better.

    But put off by Tado's insistence of sticking schedules in the cloud. And the mess they've made with Open Therms support.

    Can anyone that runs this and uses Geofencing confirm how well it works in practice? We have multiple iOS devices. So if I understand it correctly its purely dumb geofencing. I.E if any of us steps within that geographic area the heating will fire up based on the schedule. IF we all leave it the heating turns off?

    The problem we have is we live very close to town. And also our main downstairs living area is very large open plan space. Nest's geofencing seems smart enough to track when we're heading home and give the heating enough time to bring the temp up. Dumb geofencing probably wont do that :/
  34. FartyPants's avatar
    Legend! Thanks OP!

    Turned postman away today with the set I'd already bought at over £100 more (with extra TRV's).

    PS - I bought and have returned a Honeywell EvoHome kit as it was pants. My boiler guy has this kit himself and rates it very highly.

  36. Joe_Bifferos's avatar
    @Chaoscontrol this deal appears to have expired, although I suspect combi owners can use the conventional boiler bundle and just end up with a useless hot water button on the hub. It would still be a good deal.
    theprofinuk's avatar
    Damn it. I just bought the wrong one.
  37. theprofinuk's avatar
    Just realized that the deal was expired and it defaulted to the conventional boiler bundle. Yet I have a combi boiler. Do you think that I can still use the multi channel hub?
    Joe_Bifferos's avatar
    Some boilers don't use 240 v on the thermostat relay to do the switching, they use a lower voltage, I used to have a Ferroli like that. In this case the 2-channel may not work without additional electronics, because according the below diagram the CH common is connected directly to live, and the 'voltage-free' nature of the 1-channel version is potentially significant. For my Vaillant this would be a complete non-issue as I confirmed yesterday that it switches 240v, so maybe get a multi-meter out and check the voltage across the thermostat wires (when the thermostat is off!). If it is 240v you are probably going to be OK.

    Decided to give these a go, too many complications with Tado (no opentherm on UK wireless kits, need to find V3 bridge for free geofencing, TRVs expensive).

    Only problem is the starter kit arrives tomorrow, but the additional TRVs are due Jan. Wondering if I can just canecel those and grab them from Toolstation with BLC discount for similar price.

    Mine said the same regarding the TRVs arriving in January but then got an email today saying they are coming tomorrow! So hopefully yours should arrive sooner than expected
