How to use

Mount the sensor on a vertical wall at the recommended height for optimal coverage and angle it to cover the desired detection zone. Insert the battery according to the manufacturer’s instructions and pair the sensor with a Homematic IP central unit or gateway following the pairing procedure in the system documentation. After pairing, configure detection sensitivity, timeouts, and integration with lighting or alarm functions via the Homematic IP app or central control interface.

Recommendations

Install the sensor in a location protected from direct rain and strong sunlight for reliable long-term operation. Avoid mounting near heating vents, air conditioning outlets, or in places with rapid temperature changes to reduce false triggers. For outdoor use choose sheltered mounting positions such as under eaves or behind protective covers while ensuring the sensor’s field of view remains unobstructed.
