If you’re using LUM to program your lock and manage users you can have it auto relock after X minutes and also specify specific conditions when you want it to relock (e.g. Modes). You also have the ability to add an optional door sensor so it’ll only relock when it’s closed. [RELEASE] Lock User Management (LUM)
Auto re-lock can be dangerous when someone left the door open and close it later. If the person didn’t notice, the deadbolt could bang on the door frame and causing damage. Like someone mentioned, it needs to be paired with a door open/close sensor.
