My Wyze lock suddenly after a year decided to become “un-calibrated” once or twice a day.
This occurred a few days just after a fresh battery change.
The battery I used were some Varta batteries and previous sets had been working fine over the past year or so.
Anyway the lock became “un-calibrated” couple times a day, sometimes the keypad doesn’t work (PIN code rejected), and lock occasionally locks itself immediately after unlock.
Anyway, after two resets of the lock and hub, I had started to lose faith in the lock, I decided to give another brand new set of Varta a go and now after the fresh batch of battery, the lock started working as per normal again.
So if your lock becomes “un-calibrated”, especially after a fresh battery change, maybe try another set of batteries!
