Calibration failed for 1 out of 7?

  • I read through many post about calibration problems but have not been able to find one where a solution is described?

    I installed 7 Shelly 2.5 devices to automate our roller blinds. All with the same hardware, all installed exactly the same way. They all work as expected but with one of the devices I am unable to get the calibration to work!?

    I can control all roller blinds from the app and in the browser with "up", "down" and "pause" all working just fine, even for the one does just won't calibrate!

    I already tried many things:

    - Factory reset and add the device again

    - start calibration from web browser

    - start calibration from app

    - start calibration when fully closed

    - start calibration when fully opened

    - turning obstacle detection on/off

    Has anyone found a solution that works?
