Just updated to 2.6.3 and recalibrated with the door closed.
After few minutes my partner came back home, opened the unlocked door and… motor blocked. Nothing changed and unluckily few days ago the Amazon return period expired, so I have a lock which must be recalibrated continuously in order to be usable. What a disappointment.
It’s been days that with the unlocked door, I never manage to open the door at the first try, I always get the “blocked motor” but I manage to open the door on the second or third try. This mean I can’t remotely open the door through HomeKit (the main reason I bought the lock for), since it never manages to open the door from full locked. The update didn’t change anything. Today, after updating and trying and trying (with no success) I got the prompt for critical batteries (after one month of use). Tomorrow I will try with Eneloop Pro batteries.
