Yesterday the program was showing no sensor, so I did a fresh setup and all was well. Opening and closing were properly showing the status after each operation and alerts were properly working. Today, after a half-dozen openings and closings, there's no alerts and the status shows "closed for 22 hours" and no fresh history. I was going to re-setup the sensor again, but the sensor can't be found. The program (android) will still open and close the door, but status doesn't change from "closed for XX hours" (closing is immediate with no flashing light or anything). What do I need to do to resolve this?
Edit to add: during the past couple of weeks, there have been a couple of instances where the program told me I needed to cycle the door open and closed to resync it. That has worked, but I'm not even getting that resync message now.
