Hi!
Did you try to replace the batteries to see if “Motor blocked” is solved by this?
“Position detection” means the Smart Lock restarted after the problems and therefore rechecked the locked/unlocked position. This means that also calibration could have been lost / the Smart Lock tried to lock “too far”.
If the problems persists with new batteries please send a log-file with a short description of the problem and the exact time when it occured to our support team at contact@nuki.io, so they can check the details of what happend.
