What is the operating range of the sensor?
The indoor range is up to 30 meters in line of sight. Walls and obstacles may reduce the range. Ensure your gateway is within a reasonable distance.
Can I use the sensor with other smart home systems?

Check the battery, ensure the magnet is close enough, and verify the sensor is within range of the gateway. You may need to re-pair the device or reset it by removing the battery for 10 seconds.
Is the sensor weatherproof for outdoor use?
No, the sensor is designed for indoor use only. Exposure to moisture or extreme temperatures may damage it. Use a weatherproof enclosure if needed.
