TP-Link Kasa Smart Radiator Thermostat Starter Bundle - 1xKE100 Kit + 3xKE100 Valves, Energy Saving, LED Display, Smart Schedule, Alexa & Google Home Compatible, No Bridge Required

I purchased this package of 3 thermostat valves, as well as a separate package that included one smart thermostat valve.(Installing the hub and linking it to Alexa was very easy, and took only minutes to complete.)The app is simple to use and straightforward and interfaces very well with Alexa.The thermostats give you an indication of the temperature in the room where they are installed, which I found to be accurate.The easy to read display on the handle clearly shows the temperature you set the thermostat to and the temperature can be easily varied with either the handle or through the app and/or Alexa, or using voice commands, giving you total control on the heating in your home and assisting in making the heating system energy efficient (saving you money by, for example, turning down or off the heat in rooms you do not use a lot).The thermostat handles come with a large number of adapters and are easily to install (although I would advice inserting the batteries before installing the handle on the radiator, particularly if the handles will be placed in difficult to reach positions on your radiators).I found the price to be very good value for money.Recommended, to make your home warm and smart.

Easy to setup and control via app and Alexa and successfully saving us money on our heating bills

Work great, the interface is perfect. I have 2 in open areas that use their own internal thermometer to set the temperature, and 3 in areas that are more enclosed that I have paired with a tapo T310 sensor each, in better positions to more accurately gauge the temperature, the house is always at a comfortable temperature now and I can easily add scenes for when I leave the house etc to reduce the temperature and save energy.

I have had these for about a month now and apart from some teething issues I am really happy with result. You can customise temperatures in every room.Downside: I had to remove a couple of thermostats. Refit old one then use the old trv to turn radiator up and down a few times to free up mechanism. Once that's done plain sailing.

Work well and the app offers good control.

If all you're using is the Kasa app then I think you're fine with these. If you have separate Tapo products, you're semi-screwed.Once the Kasa hub is on the Kasa app, as soon as you open the Tapo app it will detect the Kasa hub and add it to the Tapo app. Then once you go into the Kasa app it will say "Oh you're using the Tapo app, we'll remove the hub from the Kasa app".This would be fine if it wasn't for the fact that you can't add the TRVs from the Tapo app, it must be done from the Kasa app. This means that you need to re-add the Kasa hub to the Kasa app, re-sync it, then when you're asked "Do you want to add a device" say Yes and add a TRV. Once that's done the Kasa hub will disappear from the app again so if you have another TRV to add in you'll need to repeat the above each time.

Does what it says on the hox

As usual with TP Link products, I am very satisfied, very easy to setup and use, setting temperature per room is a god send, no longer am I over heating rooms!! One of these thermostats was faulty, customer service helped fault find and Amazon was fast to replace, can’t fault service or the product.
