Your tado° device will show an E0 error message if pairing fails during installation.

If you’re pairing a tado° Smart Radiator Thermostat to your Internet Bridge, please try to pair again. The distance between the Internet Bridge and the device should be at least 3 meters.

  1. Make sure pairing on the Internet Bridge is activated, indicated by the blinking pairing LED.
  2. Press the button on the Smart Radiator Thermostat for 3 seconds to start pairing again.
  3. When pairing is successful, the three lines turn solid.

If pairing is not successful even after multiple attempts, please contact our Technical Support Team who will be happy to help you.
