Motion Sensor not responding, How Do I Fix?

@christopherrnewell is it SS2 or SS3 system? They are covered under a 3 year warranty. Easiest way to  address this is to first replace the battery. CR123.  If that doesn't work, remove it from the system and then add it back in.  If you need help on that try the new Help Center or call support.  Its pretty easy to do. Good luck.
