The Philio Multi Sensor is a Z-Wave door/ window sensor, motion sensor, lighting sensor and temperature sensor in one package. Thanks to this the PSM02 can be uses as a security device or home automation device, e.g. to send an alarm when a motion is detected, turn the light on/ off automatically at night or to adjust the heater.The product consists of two elements – the detector and the magnet. The magnet is mounted on the moving part of the window or of the door. The other part is placed on the frame. Note: The illumination sensor does not work with Fibaro Homecenter 2 and Zipabox yet.
