HiveSmart Heating Thermostatic Radiator Valve (TRV) with Smartphone Compatibility, White

Cannot fault this trv as it paired quickly and appeared on the Hive app. Actioned it with a Hive motion sensor without problem. In dining room boosts temperature when presence detected and can either let more hot water through if heating is on. There is an option to turn the boiler on if heating is off but that would heat the rest of the house if the Hive Thermostat is satisfied.Despite the Hive Receiver going wrong and not working with the Thermostat, the trv and sensor were still online and working on the app and control the trv state. Unfortunately, calling for heating did not work because the Receiver was down. When a new Receiver was fitted, the trv and motion sensor automatically connected to it.Apart from the cost, I must recommended this device.

Cannot recommend these enough, they are fantastic. We bought an old house and found that with a single thermostat downstairs the rooms upstairs would frequently be at a significant differential from the thermostat, too cold or too hot. These things solve the problem beautifully, I can now set the temperature individually for every room, turn off heat in rooms that aren't being used and have customised schedules for all of them.There are some gotchas that can catch you out:1) In the app if a valve shows that it's below it's target it will show the heating icon which indicates that it's requesting heat, however despite this if the current temperature isn't more than 0.5 below the target the main thermostat won't actually activate. This confused me for the best part of 2 hours, I went through many resets of all the hive devices trying to solve a problem that didn't really exist. It's very silly that it indicates that the valve is requesting heat when it really isn't, hopefully they will fix this at some point.2) After initially installing them they need some time to calibrate and may not activate when it looks like they should. I found that deliberately setting them to high and low temperatures to trigger the activation helps to speed this along. I think for the first few nights they will open/close slower than they are able to as part of the calibration cycle. TL;DR if you think they're not working but the app reports everything is fine, it probably is fine, just leave it for a bit. Also I've noticed sometimes it looks like it should be heating one of the radiators but isn't, but if you touch the radiator it's already hot. I guess there must be some energy-saving duty cycle to avoid running the boiler continuously unnecessarily.3) Leave at least a couple of radiators without these so water can flow freely. The bathroom and hallway are ideal candidates for no smart valve. Then just set the hallway manual valve to roughly halfway so that whenever any of the other radiators demand heat the hallway gets 50%. I've found this works really well.Home Assistant is also worth using as it lets you monitor all the smart stuff in the house and create automations based on events etc, and get access to all of the sensor data.These things are worth their weight in gold, I wish I'd got them sooner. Pretty sure they will pay for themselves over time too with all the insights into the system that I'm getting from the data coming off them, and the ability to not heat unused rooms. Being able to actually have the whole house be at the same temperature is so wonderful though and it's worth buying them just for that alone.

I had read many reviews on this thermostat, not all of which were positive. So, although I ideally needed four of them, I bought one first to try out and see for myself what the probems are. Well, all I can say is that in my case, it works perfectly so far. Set up was a breeze. I set it up in the same room as the hub before installing onto the radiator (as recommended by another reviewer). It took less than five minutes to complete setup via the Hive app. Installation onto the existing Danfoss valve was straightforward, although the allen screw was very stiff to tighten up. It's only been 24 hours since installation so I can't comment on reliability and battery life, but so far it's coming on and going off when it should, and reaching the set temperature. My only major gripe is the price. Like many purchasers of this product, I chose it because I wanted it to run off the same hub and app as my Hive system, and didn't want yet another hub and app. I feel that Hive are taking advantage of this by charging the price they do, as there are other brands available at half the price. I've knocked a star off my rating because of this, not because of its performance.

I recently installed the Hive Smart Heating TRVs, and while the setup was a bit fiddly, I managed to get them working fairly quickly. The installation guide was clear and straightforward, so that helped smooth things out, even if there were a few steps involved.Once set up, the TRVs synced up well with my existing Hive thermostat, and the app control is genuinely smart and convenient. It’s great to be able to control individual radiators from my phone, especially for managing the heating in different rooms without needing to adjust everything manually.One thing to note, though: the temperature reading on the TRVs isn’t an exact reflection of the room’s temperature. It’s more of an approximation, which I didn’t realise until after installation. Not a dealbreaker, but something to be aware of if you’re looking for super-precise room control.Overall, they’re pretty solid value for money, and I’d recommend them if you’re after a high-quality smart heating solution with the flexibility to manage zones individually.
