Suitable for

This sensor may not be suitable for environments without a compatible Zigbee hub, as it cannot connect directly to standard Wi-Fi networks. Additionally, it is not designed for outdoor use in extreme weather conditions or areas with high humidity, which could interfere with the sensor's internal components and signal reliability.
Key specifications
Connectivity: Zigbee 3.0
Detection type: Magnetic reed switch
Power source: Battery operated
Compatibility: Zigbee-enabled smart home hubs
Installation: Adhesive mounting
To use the sensor, first pair it with your Zigbee hub through your smart home application. Once paired, clean the surface where you intend to mount the device to ensure the adhesive holds securely. Place the main sensor unit on the door or window frame and the magnet on the moving part, ensuring they are aligned according to the manufacturer's guidelines. After installation, you can configure automation rules in your app to trigger actions such as turning on lights or sending alerts when the sensor state changes.
What to consider before purchase
Ensure you have a Zigbee gateway or hub
Check the distance between the sensor and the hub
Verify the surface material for adhesive mounting
Consider the battery replacement requirements
For optimal performance, ensure the gap between the sensor and the magnet is within the recommended range during installation. Regularly check the battery status in your smart home app to prevent unexpected downtime.
