My Food Bank work office has a motion sensor to turn on the lights.
Occasionally after working at my desk for a while the lights go out.

Does anyone have experience with the #Wink #Zwave #MotionSensor ? Mine keeps detecting motion constantly. It's in a small closet like room. I can't figure out how to fix it, I've tried adjusting the sensitivity level, changing the battery and a factory reset but for some reason it's just flipping the fuck out. I can't find anything online and it appears contacting wink will not help me any as they are now some sort of subscription only service. Any help is appreciated.
