tado°

tado is a German company from Munich making smart thermostats and radiator valves for heating and cooling. The system uses geofencing to turn the heating down when nobody is home, detects open windows, and reports where energy is being used and saved. It works with most common heating systems.

German development makes tado a European alternative to the American thermostat brands, and its focus stays on cutting energy use rather than on automating a whole house. It suits households and landlords that want to control heating room by room in a building that already exists.
