Your tado° device will show an E0 error message if pairing fails during installation.
If you’re pairing a tado° device to your Internet Bridge, please try to pair again. The distance between the Internet Bridge and the device should be at least 3 meters.
Make sure pairing on the Internet Bridge is activated indicated by the blinking pairing LED.
Press the button on the Smart Thermostat/Wireless Temperature Sensor for 3 seconds to start pairing again.
When pairing is successful, the two chain links stay joined.
If pairing is not successful even after multiple attempts, please contact our Technical Support Team who will be happy to help you.
