The auto unlock feature correctly detects when I leave the area and come back (Wifi pro with door sensor)
The problem is that it often relocks before I get to the door. I do have my auto lock set to 10 sec because I when I leave I want to hear it lock before I get too far from the door. It seems that when there is an auto unlock I should be able to set a longer relock interval or be able to disable the re-lock.
