Third Reality Zigbee Door/Window Sensor

The Third Reality Zigbee Door/Window Sensor is an affordable contact sensor for monitoring doors, windows, cabinets, and drawers. This magnetic sensor reports open/closed status to your Zigbee hub, enabling security alerts and automations. The compact design allows discrete installation on virtually any hinged opening.
