WiFi Smart Thermostat for Boiler 3A 220V Compatible with Alexa, Digital White Boiler Thermostat Programmable Tuya/Smart Life APP Remote Control, Dry Contact

I got this WIFI Thermostat to replace a basic unit for a combi boiler which went faulty. It programmed in to the SmartLife App and Alexa very quick and with ease.The unit is very nice looking and works very well, everytime. The controls and displays are very clear and simple to operate manually, automatically or by using Alexa.Easy operation within house and remotely to put heating up or down as required.The unit works really well with Alexa with simple commands..ie: "Heating 18 or Up 2 or down 3".. can also question "Whats the heating Temperature" gives you instant temperature of house from anywhere. Also visible & controllable on screen or on mobile.The DIY Installation was fairly easy as I didnt need to go into the boiler for connections, but recommend a 40mm deep back box for unit & cables. I found connections clear, but I do have electrical background. If unsure you will need to get a Gas Safe/Spark Engineer in to install. Basically a great unit, good value which looks good and works extremely well.

I've been looking for a central heating programmer and thermostat to replace a battery powered one that doesn't work with Alexa . This one fitted the bill and I ordered it.It arrived on time and I set it up on my workbench. I already have a Smart Life appliance so it was only a few seconds before it was set up and functioning. I was very pleased with the programming flexibility and only found a slight problem with the colours used in the app where some links were shown as white on a very pale grey background so almost invisible,The instructions for setting up were clear and easy to understand but I was a little surprised that there were no instructions about fitting the unit. Fortunately as an engineer I realised how it was mounted but wonder if anyone without that background would understand how to do that.As my CH boiler is switched on by a live mains connection to the wire from the boiler I could use the uncommitted relay output to simply extend that to operate the heating.Overall very pleased with the purchase and hope that it will last as long as the old programmer has.Time will tell but I do like the ability to control all aspects of my CH boiler from my iPhone and can turn it ona dnoff and set the temperature by talking to Alexa.

The thermostat was easy to install and connect to the Yuya app. It works well but I discovered the accuracy could have been better when checked against a digital thermometer. The thermostat calibration can be adjusted from setting's within the app. However, there is no mention of carrying out this procedure in the instructions so I have marked it down a star.

I can’t even begin to say how impressed I have been with this thermostat. I replaced one which even though relatively new was extremely difficult to set up the program times on and off. I switched it over myself which was an absolute breeze using the already installed probe. The app excellent and is really easy to use which meant I could program it exactly how I want without having to have the same settings Monday to Friday. It did easily connect to my Alexa devices so I can simply tell Alexa to set the underfloor heating to 30 degrees if I want to boost the heating in between. Only downside is the display which I think could look better and that some of the light leaks out from the sides which I notice at night but that really is a minor thing. Great value for it’s price

Overall I’m pretty pleased with this unit. Installation was simple enough, however mine was complicated by two factors... firstly the unit is deeper than the thermostat it was replacing. Even with a standard size backplate, this new unit wouldn’t fit. So I had to buy a ‘spacer’ to put between the wall and the unit. It’s so much deeper, that even with this spacer, it only just fits, I very nearly needed two.Secondly it was complicated by the wiring for the floor temperature probe, specifically the type of connector at the back on the unit. In the box is a new temperature probe, this has a two thick metal ends which plug into the unit. There was already a probe in place, so rather than disrupt everything I wanted to use the existing one. In theory not a problem, however the new unit wouldn’t take bare wires... no matter how much you tightened it they would slip out and the one time I did manage to get the unit mounted without them falling out, on power up it came up with a floor sensor error message.The solution was the cut the wire provided in the box, with the two thick metal ends, and join the existing wires to the new wire. Ultimately that worked, but was a bit of a pain.However now it’s installed and set up, I’m pleased to report a few good things too.Firstly it’s really easy to use, either via the Wi-Fi app or using the controls on the screen. It’s so much more intuitive than the traditional unit it was replacing which required a degree in jibberish to programme. Switching between the timer programme and manual control is easy and it works with my Alexa and again, this was easy to set up.Secondly, having suspected the old thermostat was faulty, this has given new life to an old underfloor heating system in our kitchen. There is now a nice toasty warmth underfoot and the ambient temperature of the room is greatly improved as a result.Pretty happy overall, but marked down one star for each of the installation issues.

Good quality. Looks so much nicer on the wall. Works well with 3 cable boiler setup. I can now operate heating from anywhere.

Installed and connected to WiFi OK. However, it keeps dropping connection so is basically useless. None of my other devices drop out like this. Little point in having a device I have to reconnected every few hours or less. Totally unreliable.

Great value for money. Quick and easy to install and connected immediately to app for programming use.
