Fwiw after four warranty replacements for exactly this issue it’s still unsolved. I’ve got another lock in a separate door that works just fine, but this calibration loss is a real frustrating problem.
I am experiencing the same thing. I have had to calibrate mine almost daily and today I have had to do it twice in the last 3 hours. It has only been since it had gotten hot outside in the last month or so that this has been happening.
Something is wrong for this to be happening this much.
Still happening in 2024.
This issue has long since been fixed for me.
What was the fix?
They issued a firmware update for the lock a long time ago that fixed it for me.
