Does tado° work with OpenTherm heating systems?

tado° supports many heating system interfaces, including the OpenTherm protocol. In case your boiler controls hot water production, you will also be able to control these settings via tado° once it is connected to your boiler. As Open Therm is a digital bus interface, an Extension Kit generally is not required for hot water control.

If you do not already have a wired room thermostat the Extension Kit is needed as wireless receiver for the Smart Thermostat.
