## Long description

Sonoff SNZB-04P ZigBee wireless battery-operated contact sensor detects and reports the open or closed status of doors and windows to a compatible ZigBee hub. Designed for unobtrusive installation on frames and sashes, the sensor enables remote monitoring and integration with home automation scenes. It operates on battery power and communicates over ZigBee, allowing it to trigger notifications, alarms, or automated actions such as switching lights or adjusting climate controls when door or window status changes.
Advantages
The sensor provides reliable open/close detection with low power consumption thanks to battery operation and ZigBee communication. Its compact design fits standard door and window frames and supports seamless integration with ZigBee ecosystems for automation and security workflows. By reporting status changes in real time to a hub, the device supports energy-saving scenarios and enhances home safety without the need for wiring.
Suitable for
Home security monitoring of doors and windows

How to use
Attach the sensor body and magnet to the door or window frame and sash so that they align when closed. Insert the required battery following the device instructions and pair the sensor with a ZigBee hub using the hub’s device-adding procedure. Once paired, configure notification and automation rules in the hub or companion app to receive alerts or trigger actions when the contact state changes. Periodically check battery status in the hub and replace the battery as indicated.
Usage recommendations
Install the sensor on clean, dry surfaces and ensure correct alignment between the sensor and magnet for reliable detection. Place the sensor within the ZigBee network range of the hub or through a mesh network of repeaters to maintain stable communication. Use the hub’s battery status alerts and set automation delays or conditions to avoid false triggers from brief openings.
