Description
The THIRDREALITY Door & Window Sensor is a smart contact and magnetic sensor that instantly alerts you when doors and windows are opened or closed. Thanks to the Zigbee 3.0 protocol, this sensor works seamlessly with popular home automation platforms such as Home Assistant (ZHA/Zigbee2MQTT), Homey, SmartThings, Hubitat, Aeotec, Echo (with built-in Zigbee hub), Eero 6, and more. The optional Smart Bridge MZ1 also integrates the sensor with Apple HomeKit and Google Home.
Key benefits:

- Ease of installation: Simply attach the sensor with double-sided tape or screws (both included), no tools required.
- Overview & History: View the sensor's status and history, including battery status and low-battery notifications, in the Third Reality app or Alexa app.
- OTA updates: Firmware updates are done wirelessly via the app, so you're always up to date.
- Safe & Reliable: For indoor use only. Do not place on metal doors/windows for optimal performance.
