## Description

KETOTEK Smart Thermostat WiFi for Electric Underfloor Heating 16A Compatible with Alexa, Programmable Underfloor Heating Thermostats Controller with NTC Probe Sensor : desertcart.co.uk: DIY & Tools

Review: Great WIFI Thermostat - 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.
Review: Great piece of kit - 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

### ⭐⭐⭐⭐ Great Smart Thermostat
*by M***P on 27 October 2024*

I have 3 of these, 2 working with wet underfloor heating and 1 with electric underfloor heating. 2 are connected to underfloor remote sensors. I also have 2 NEST thermostats and apart from the ability to learn (which is a double edged sword) I would rate these as good as the NEST thermostats. I automate the thermostats through Alexa but have to run them through the Tuya app as they cant be controlled properly through the Smart Life app when I set them up (scrolling bars didn’t work). Overall good value for money, work well and look good. 1 star lost because the software is a bit clunky.
