I already have a Smart Thermostat, how do I make it compatible with Apple HomeKit?

To use HomeKit with your Smart Thermostat, you need the new HomeKit enabled Internet Bridge. All "v3" Starter Kits contain a free upgrade to the new Internet Bridge.

If you own or rent a Smart Thermostat with our earlier model of the Bridge (without pairing button), you can simply replace your existing Bridge with our new HomeKit enabled Internet Bridge. There is no need to replace other tado° devices.
