How to use
Mount the sensor body on the fixed frame and the magnet on the moving part (door or window sash) so that the two parts align when closed. Follow the Homematic IP pairing procedure using the system’s gateway or app to add the sensor to your network and confirm correct communication. After installation and pairing, use the central app or gateway to configure actions, notifications and automation rules based on the sensor’s open/closed status. Replace the battery when the system indicates low battery status.
Usage recommendations
Install the sensor on clean, dry surfaces and position the magnet within the manufacturer’s recommended alignment distance to ensure reliable detection. Avoid mounting on metal surfaces that can interfere with wireless range; if necessary, test signal strength before final fixing. For long-term reliability, use the battery type specified by the system and check device status periodically in the Homematic IP app.
