Home kit-enabled multi-sensor that detects motion, measures temperature and light intensity, and it has an accelerometer to detect any tampering.
Trigger scenes based on detected motion. For example, turn the lights on when the sensor detects motion in the room.
Use Siri to check the status of your sensor, just ask "hey Siri, what is the temperature in the living room".
You can set up the Fibaro motion sensor from the Fibaro app directly from your iPhone, iPad, or iPod touch in a few easy steps.
Battery-powered and completely wireless, featuring a smart bracket with grip that allows it to be affixed almost anywhere.
