The SONOFF SNZB-04P is a Zigbee 3.0 wireless door and window sensor designed to enhance home security and automation systems. It detects the opening and closing of doors, windows, cabinets, or gates in real time and communicates instantly with a compatible Zigbee hub.
Once connected to the eWeLink app, the sensor sends immediate push notifications whenever activity is detected. This allows homeowners to monitor entry points remotely and stay informed about any changes, whether at home or away.
Built on the Zigbee 3.0 protocol, the SNZB-04P offers stable, low-latency communication and supports local smart scenes. Even if the Wi-Fi connection is interrupted, Zigbee-based automations within the local network can continue operating, ensuring reliable performance.
The sensor supports advanced automation features. Users can configure it to trigger lights, alarms, cameras, or custom smart scenes when a door or window is opened or closed. This makes it suitable not only for security applications but also for convenience and energy-saving routines.
Equipped with tamper detection, the device sends alerts if it is removed or interfered with. Powered by a long-life CR2477 battery, it can operate for over five years under normal usage conditions, reducing maintenance requirements.
The compact ABS housing and tool-free adhesive installation make it easy to mount on doors, windows, cabinets, or similar openings without drilling or complex setup.
