Wouldn’t it be nice if your motion sensor could double as an emergency light when power goes off? The idea is even more practical when it only goes on when motion is detected. Why waste battery power when it is not needed especially during the day or sleeping or away.
Looking through the Fibaro Motion Sensor documentation, I think this is possible:
You would have to have your Internet connection and SmartThings backed up with a UPS and need a power loss event (several posted on forums). Then the mode on the Fibaro needs to change to Flashlight:
Flashlight mode - LED glows in white through 10 seconds. Each next detected motion extends the glowing by next 10 seconds.
Seems like a project up @wackware’s alley.
