How to use

Install the detector at the recommended height and orientation for the intended coverage area, choosing wall or ceiling mounting depending on the room layout. Pair the device with a HomeMatic IP central control unit following the platform's inclusion procedure. Configure detection-based actions, such as switching lights, arming alarms or activating scenes, within the HomeMatic IP app or management interface. Verify detection coverage and adjust positioning if there are blind spots or false triggers.

Recommendations

Position the sensor to avoid direct exposure to heating vents, air conditioners or large glass surfaces that may cause false detections. For consistent performance, keep the device free of dust and ensure the mounting surface is stable. Test the detector after installation and periodically review detection events in the HomeMatic IP app to fine-tune sensitivity and placement.
