With the Tado Smart Radiator Knob X Starter Pack 8-pack, you can regulate the temperature per room. Even if you don't have a boiler. You can control the radiator knobs via the app on your smartphone. There, you can also find extra functions to save energy. Set temperature schedules so the heating is only on when you're at home, for example. Or let the thermostat do so automatically via geofencing. Thanks to the open window detection, the heating is turned off automatically when the window is open. This way, you save energy. For these extra functions, you need an Auto Assist subscription of € 3.99 per month. The radiator thermostats of the Tado X series work with the Matter smart home platform. This allows you to connect it to other smart devices.
