I have an occupancy sensor (lrf2-ocr2b-p-wh) in a hall closet that's worked fine for a year, but suddenly no longer works properly (i.e. it doesn't turn the light on or off).1) When I press the light button on the sensor, the correct light does turn on/off, so it's clearly still paired.2) When I enter test mode, the sensor shows that it's clearly detecting motion.However, out of manually pressing the button or test mode, the sensor doesn't seem to do anything anymore.I have other occupancy sensors in that house of the same model that still work fine. Any ideas?
