Overview

SONOFF SNZB-04P is a Zigbee 3.0 door and window contact sensor designed for real-time monitoring of openings and closures. It enables automations such as triggering lights, alarms, or notifications when doors or windows change state, making it suitable for both security and convenience scenarios.

The sensor operates on the Zigbee network and integrates with compatible Zigbee coordinators, including Home Assistant via ZHA or Zigbee2MQTT. It includes a tamper alert to notify if the device is removed or interfered with, and is powered by a long-life battery for low-maintenance operation. Correct alignment of the sensor and magnet is required for reliable detection.
