Description

Note: this radiator thermostat doesn't work without Tado starter pack of the X series.

Control the temperature per room with the Tado Smart Radiator Knob X. You can control the radiator thermostat via the app on your smartphone. Here, you can set extra functions to save energy. With geofencing, the thermostat knows if you're home and turns the heating on or off automatically. Or create schedules for this, so the heating is never on unnecessarily. For functions like geofencing, you do need an Auto Assist subscription. This costs € 3.99 per month. The radiator knob works with the smart home standard Matter. This means you can connect it to other Matter devices. When the battery is empty, you can charge it with a USB-C cable. Note: this radiator thermostat doesn't work without the Tado starter pack of the X series.

I still have to get used to Tado

Looks good
Temperature setting works moderately. The set temperature is always exceeded by almost 2 degrees

I wanted to be able to set our room to a temperature. With Tado that is quite difficult and maybe even impossible. But I keep trying to improve the settings

Ridiculous subscription makes products unusable.

Design
Easy to install
Subscription costs

Since October, you have to pay €4 per month to heat individual rooms with tado radiator valves. Without a subscription, they can no longer tell the tado main thermostat to turn on the boiler. I returned the products and am now opting for Plugwise. That solution is completely local, so there will never be a subscription fee.

Top system, works fantastic

Works super easy
Easy to mount on your heating
save energy
Subscription if you want to use geo-fencing (worth it)

We replaced our remeha thermostat with tado + smart radiator valves 6 weeks ago. We saved 30% energy in the first month. If this continues, we will quickly recoup the investment. We are very happy, and also because it is now only warm when it needs to be warm in the (bath)rooms.
