Easy to install and looks great. It works well with Home Assistant.
š”ļø This thermostat is an attractive device in light plastic with a white LED display. I looked at several TRVs, and there were several factors that influenced my buying choice. With this TRV, I liked that there was no unnecessary distance between the valve bottom and the connector to the radiator. I saw this in other valves and thought that this one by Sonoff looked far better. I also like the LED display that shines through the plastic over the backlit LCD display that some TRVs give you. Everything came well packaged and protected in its box.š”ļø Setup is straight-forward, and I recommend that you read the online manual. This goes through everything you need to know and has an English section at the end. I used some long-life batteries, and after inserting them, I just needed to install the valve. During installation, I managed to press the button that flips the display upside down. This was easy to rectify once I looked at the manual.š”ļø The thermostat is relatively easy to fit. My one concern is that you definitely need to measure the clearance around your radiator, particularly between the valve and the wall. This thermostat is not the bulkiest out there by any means, but it is substantial, and this only cleared my wall by about 1mm. Otherwise, fitting took a few minutes for me. My radiators are all modern and have the standard M30 valve that this TRV fits without having to resort to the included adapters. A key feature that attracted me to this thermostat was that the connection is made of metal, which gave me confidence that there would be a strong connection to my radiator. A metal connection, not plastic, was a deal-breaker for me.š”ļø The other criteria for purchasing is that I am quite happy with the brand and I have many Sonoff devices, including my gateway. My connection protocol is ZHA over Zigbee, and I expected a TRV from the same manufacturer of the gateway to work seamlessly, which it did. Not that I expected anything different as this is a Zigbee 3.0 device; I just wanted peace of mind.š”ļø I used some long-life lithium batteries to run this. They are expensive, but I wanted to get the most out of this valve before needing to swap the batteries once more. I was quite happy with not having the batteries provided, as I think that this is a personal choice. I could have just installed a couple of generic batteries from the big box I purchased from my local supermarket, and that would have been no better than what would have been provided if the batteries were included. I opted for high-quality ones instead.š”ļø Pairing was straight forward, and thankfully this is one of those Zigbee devices that seems to tolerate pairing in situ rather than close to the hub gateway. I did need to pair it twice, as the first time was successful, but the TRV was unavailable in Home Assistant. I paired again, and everything sprung to life. I will not be using the app or eWeLink as I have Home Assistant. There is some hype about interoperability with Google and Alexa, and I can indeed control this valve in that way, but that has nothing to do with the valve itself. Once you have the device paired with your hub, then you can connect up external services to do whatever you want, and I can indeed ask Alexa to change the temperature, but only because I have paid to make that happen and have leveraged the capabilities of my hub and network. Some Alexa devices can act as a Zigbee gateway and so could pair with this TRV, but I have not needed to test this as I have a more capable system already installed.š”ļø I wonāt go into the operation as this device uses the thermostat card, and it depends on the protocol and hub platform you are using. The TRV was very responsive to commands, although the only downside, which is common to all electric TRVs, is that you can hear the motor when the temperature demand changes. I am also not sure if I like that the valve lights up when it is dark in the room. Again, all similar TRVs do this, and I have not discovered if I can control this. I suppose I will just have to put up with it. On the whole, I am quite happy with it and the way that it functions. You will probably need to have other temperature sensors rather than rely on the one built into the TRV, which is next to the radiator.š”ļø I do like that the valve has frost protection, but thatās only going to work if I have created automations to allow this TRV to demand heat in those situations. I mention this because the work to install this TRV is the tip of the iceberg when it comes to getting the most out of a TRV in home automation, and this is true of all such devices. Looking at the built-in temperature sensor in the TRV, it seems accurate enough against the ambient temperature in the room where it was installed. The TRV also has window detection, which simply detects a rapid drop in temperature. This is a feature that I wonāt be using, as there are other reasons why this feature can be fooled, such as opening the door to the room where the TRV is located and letting in cold air. I prefer to put a separate sensor on the window and detect opening to switch off the TRV that way.š”ļø I installed this device on a radiator in my daughterās bedroom. I can automate the heating to keep the room cool when she is away at university and warmer when she returns home. This is the neat thing about TRVs like this: if you know what you are doing, you can get creative. This device lives up to that and is very easy to work with. Manual control is also easy, and you just turn the control on the top to set the temperature. I recommend putting it into child lock mode, as the control is very easy to turn. I am very happy with how the valve performs, and the control is quick and responsive. āļø

Highly recommend these. Great functionality for a great price!
I now have these on every radiator in the house, all accessible through the eWeLink app and integrated with Alexa. They really are excellent, they come with a full set of adaptors to match existing TRV bodies, easy setup and nice clear digital display. I read negative comments about the temperature reading that the TRVs give. I think it is unavoidable that a temperature sensor located right next to the radiator is going to be inaccurate. I bought a handful of Sonoff temp/humidity sensors and have one in each room. I then use the eWeLink app and Alexa to control the TRVs based on the reading given by the Sonoffs rather than the TRV temp sensors. Compared to other systems, these are a great price for the quality, and they are often on an Amazon sale offer.

Works great with Home Assistant (Zigbee2MQTT)
Product is great, but the instructions are terrible. I had to lookup how to manually pair with Home Assistant. You have to take the batteries out, then put them back in while holding down the main button. Once I did this Home Assistant found this device straight away using Zigbee2MQTT. In terms of noise I found it a lot quieter than I was expecting. I have one setup in the bedroom and can hardly hear it from my bed. The noise of the hot waters initial flow through the radiator is far nosier. I have this setup in an automation so my bedroom radiator turns on for an hour in the winter mornings, then off for the rest of the day when the room isn't used.

Excellent product
I bought 8 of these for the radiators in my house and 4 for my parents house and all have been working great for the past month. I'll update this review if they prove unreliable but, so far they work great.They work with both the Sonos Hub or an Alexa Echo. Note you need to use an actual Echo not something like an Echo dot. The only advantage with the Sonos hub is that you can see the battery level which doesn't seem to show on the Alexa app. To add to Alexa you need to select the 'Other' option when adding a device type and select 'Zigbee'.Installation is a breeze, just pop the batteries in (it takes 3 AA), replace the existing valve with it ( a 2 min operation) and follow the instructions to pair with either the Sonoa hub or Alexa.I use this separate from my heating in that I keep the valves at around 27 degrees and then simply turn on or off the ones i want using Alexa. When the heating is on, the ones that are on are heating the room to the maximum and the ones that are off aren't. Think of it like I'm physically running round manually shutting off or turning on the valves manually except I can do that with a voice command from alexa. You can group the valves in Alexa to be anle to tirn on or off multiple valves together.Finally, the Sonos is a great price (one of the cheapest) and because it uses Zigbee rather than Wifi, its not using up one of your device limits on your router.Very pleased with these units so far but, will amend this review if I start to see any issues. Hope this review is of use to someone.
