Summary
Allow to invert LEL to indicate locked doors and not for unlocked doors.
Features
Our door is unlocked most of the time, but every morning it is unclear if the door was already unlocked after the aut-lock at night.
In that case the blinking LED would be helpful to show “still” locked. I would guess it is a simple but helpful feature. In my case it is the more battery friendly variant. At the moment we not use the LED for unlocked doors at is to nervous.
