Homematic IP HMIP-SMI55-2 Passive infrared (PIR) sensor Wired & Wireless Wall White

INCREASED COMFORT AND SECURITY Automatic light control when motion is detected. Depending on the brightness in the room, the light is switched on only when it is needed, for greater convenience and energy savings. As part of a Homematic IP security solution, the motion detector can not only switch on the lights but also trigger an alarm. ALL-IN-ONE: MOTION DETECTOR AND SWITCH The integrated push-button offers manual control of devices or system functions – independent of motion detection. EXTRA-LONG BATTERY LIFE With two micro-batteries, a battery life of typically 4 years is achieved, offering low-maintenance work for the device. When using the motion detector in a Homematic IP security solution, a Homematic IP Power Supply Unit for brand switches (HmIP-BPS) is required for power supply.
