Unlock by Timer unlatched my front door

Today my daughter woke me up to tell me that our front door was open. The timer controlled unlock must have unlatched it accidentally. My trust in that particular feature is gone… What if that had happened when we were on holiday?

What could possibly have happened? Could it have been the firmware update to 4.2.6? Might that update have lost the lock’s calibration? (I noticed that after the update the lock stopped blinking when unlocked - so the update might have changed or deleted some settings…)

Please contact our support via the Nuki App (Menu > Help > Contact Customer Support) as this is an individual problem and might require sharing logs and other sensitive data.

Done. Ticket #442653
