## Long description

Homematic IP 159903A0 is a compact indoor motion detector designed for wall mounting in Size 55 frames. The device combines wired and wireless connectivity (868.0–868.6 MHz) and runs on AAA alkaline batteries, making it suitable for retrofit into existing switch series and for installation where mains power is not available. Housed in an anthracite enclosure with dimensions of 86×86×21.5 mm, the detector provides presence detection, lighting automation and alarm signaling for homes and offices, and can communicate with other Homematic IP devices with a radio range of up to 150 m in open space.
Advantages
The motion detector supports both wired and wireless operation, offering flexibility for new installations and retrofits. It detects movement across a wide 110° field of view and can trigger lighting or alarms depending on ambient brightness and configured rules. A manual button on the unit allows local control independent of motion events. Communication between devices can occur locally without internet access, ensuring continued alarm reporting and basic automation even during network interruptions. The compact anthracite housing and Size 55 compatibility enable integration into common switch ranges.
