The SONOFF SNZB-04PR1 is a compact wireless sensor designed to monitor the opening and closing of doors, windows, and other movable elements in a smart home. Thanks to Zigbee 3.0 technology, it enables a fast and reliable connection to a compatible Zigbee gateway and easy integration with other smart devices.

The sensor consists of a main unit and a magnet, which together detect changes in the position of a door or window. When a door or window is opened or closed, the status change can be displayed in the eWeLink app, a notification can be sent to the user, or a selected smart automation can be triggered.

Smart Automations for Greater Comfort and Security

You can connect the SONOFF SNZB-04PR1 to other compatible devices to create various smart scenarios. For example, when the front door is opened, the lights can turn on automatically, an alarm can be triggered, or another predefined automation can be executed.

The sensor also allows you to review the event history, so you can check when doors or windows were opened or closed. A low-battery alert is also available.

Protection Against Unauthorized Removal

The SNZB-04PR1 model includes a function that detects tampering with the device or its unauthorized removal. This provides an additional level of security when used on entry doors, windows, or other critical locations.

Easy wireless installation

No additional wiring is required for installation. Simply mount the sensor and magnet on the door or window. When the door or window is closed, the distance between the main unit and the magnet must be less than 20 mm.

Power is supplied by a replaceable CR2477 battery, allowing you to flexibly install the sensor in various indoor locations.
