SONOFF Zigbee Smart Door/Window Sensor SNZB-04PR1

For door and window control Requires a Zigbee control panel Accessory for a wider smart home

The smart sensor is intended for users who want to easily monitor the opening of doors or windows in their home and trigger automations through an existing smart system.

  • Notifies of opening or closing for basic security and an overview of what is happening at home.
  • Connection via Zigbee allows it to operate as part of a larger smart system without overloading the WiFi network.
  • It triggers various scenarios, such as turning on the lights upon entry or notifying you of an unusual opening.
  • The compact design allows for discreet installation on various windows and doors.


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 allows for 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 a change in the position of a door or window. When a door or window is opened or closed, the change in status can be displayed in the eWeLink app, send a notification to the user, or trigger the selected smart automation.

Smart automation for more comfort and security

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

The sensor also allows you to view event history , so you can check when doors or windows were opened or closed. There is also a low battery warning.

Protection against unauthorized disposal

The SNZB-04PR1 model includes a tamper detection feature, providing an additional level of security when used on front doors, windows, or other sensitive locations.

Easy wireless installation

No additional wiring is required for installation. Simply attach the sensor and magnet to 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 .

The sensor is powered by a replaceable CR2477 battery , so you can flexibly install it in different places indoors.

It is important to know

Before purchasing this smart door or window sensor, it's crucial to consider how you'll connect it to your smart home and whether you already have a suitable control panel. When choosing similar devices, the practical implications of connectivity and the possibility of integration into a larger system are often overlooked — especially if you want your equipment to work smoothly together.

  • Without a Zigbee control panel or a suitable hub, this sensor will not work - it requires an external control panel for connection and integration.
  • No WiFi support – remote access and management via mobile app is not possible without a suitable Zigbee system or ecosystem.
  • It works best for detecting openings/doors or windows in a room where you already use a Zigbee control panel, as it allows for inclusion in automated smart home scenarios.
  • Connecting via Zigbee means less load on your home internet and greater stability within the local network if you don't need cloud functions.

In practice

🟢 Door and window monitoring

Very convenient - the sensor is designed specifically for monitoring the opening/closing status of doors or windows and enables basic local notification in connection with a Zigbee control panel.

🟡 Integration into a wider smart home

Suitable with limitations – the sensor integrates well into Zigbee ecosystems, but a central unit and compatibility with your system are essential for use.

🟡 Remote control via app

Suitable with limitations - remote control is only possible if your Zigbee control panel allows it (e.g. via an additional app and internet connection), otherwise operation is limited to the local network.

🔴 Use without additional control panel

Less suitable – standalone operation is not possible, the sensor does not work without a suitable Zigbee interface or hub.

Answers to frequently asked questions

Does the sensor work without a Zigbee hub?

No, a Zigbee hub or interface is required for operation, as the sensor does not have its own WiFi support.

Is this sensor compatible with all Zigbee control panels?

The sensor is designed for use with Zigbee hubs, but it is recommended to check compatibility with your control panel manufacturer before purchasing.

Can I receive notifications on my phone with this sensor?

Notifications to your phone are possible if you have a Zigbee control panel that supports connection to a mobile app and remote notification.

Does the sensor detect the opening of all types of doors and windows?

The sensor is designed for standard doors and windows; for special hardware designs or materials, check the mounting options.
