I recently set up my tado° Wireless Smart Thermostat X via the Matter integration with my SmartThings Hub V3.
The device is correctly linked to the heating system via the tado° Wireless Receiver X, and it functions perfectly within the native tado° app.
The Issue
After pairing the device using the Matter QR code, SmartThings is only recognizing the device as a simple Temperature Sensor (reporting the current room temperature). It is not exposing the Thermostat Cluster (the actual control functions).
I tried clicking “Select other driver,” but unfortunately, no other drivers were shown or available for this device. It seems stuck on the generic Matter Sensor driver.
That’s correct, based on the Matter standard and official compatibility, this should be working as a full thermostat, but unfortunately, it is not functioning correctly on SmartThings yet—it remains locked to the Sensor profile.
Interestingly, when I linked the same tado° X device to Alexa (using Matter Multi-Admin), it works perfectly and is fully manageable as a thermostat (setpoint, mode control, etc.).
This suggests the issue is specific to how the SmartThings platform is currently interpreting the Matter Thermostat Cluster exposed by the tado° X device.
One could now look at the driver logs to see if there’s something wrong with the modular profile matching. However, that’s quite complex and time-consuming…
