Sonoff Door Window Sensor (Zigbee)

Product Introduction

The Sonoff Door Window Sensor (Zigbee) is a compact wireless contact sensor designed to monitor the open or closed status of doors, windows, cabinets, and other entry points. Using Zigbee 3.0 connectivity, the sensor communicates with a compatible Zigbee hub to provide real-time status updates and trigger smart home automation routines.

When a door or window is opened or closed, the sensor instantly sends a signal through the eWeLink smart home platform, allowing connected devices to respond automatically. This makes it ideal for enhancing home security, monitoring access points, and automating lighting or alerts.

Battery-powered and easy to install, the sensor consists of two small components that attach to the door or window frame. Its compact design allows it to blend discreetly into modern homes while providing reliable monitoring.
