Know the moment any door or window opens. The SONOFF SNZB-04P is a Zigbee magnetic contact sensor that sends instant alerts to your phone when a door or window is opened or closed. Its compact two-piece design uses a magnetic reed switch for reliable, maintenance-free detection.

Installation is simple — peel-and-stick adhesive or screws let you mount it on doors, windows, cabinets, safes, or any opening in seconds. The CR2477 battery provides up to 3 years of operation with zero maintenance.

Build powerful smart home automations: turn on lights when a door opens, activate security cameras, trigger alarms, or send notifications to your family. As a Zigbee 3.0 device, it works with open-source platforms like Home Assistant for fully local control — your security data never leaves your network.
