Sonoff SNZB-04P ZigBee Door and Window Sensor

With the Sonoff SNZB-04P, you can easily secure your home – this smart door and window sensor reliably detects the opening and closing of doors or windows. Thanks to the Zigbee 3.0 technology, it seamlessly integrates into your smart home and allows for a variety of automations: For example, let the light automatically turn on when you open the front door, or receive a notification if someone unauthorized opens a window. Installation is very easy, as the sensor is attached with strong 3M adhesive tape. The compact design ensures that the sensor remains inconspicuous, while the integrated tamper detection provides additional security. Even if someone tries to remove the sensor, you will be immediately informed. With the included magnet, the sensor precisely detects the closing state and reliably transmits the data to your Zigbee hub. You can use the sensor with Sonoff gateways such as the ZBBridge or ZBDongle – but also with other Zigbee 3.0-compatible systems like the Amazon Echo or SmartThings. The range is up to 30 meters indoors. An LED display informs you about the status, e.g., when pairing or in case of error messages. Power is supplied by a long-lasting CR2477 button cell, which you can easily replace if necessary. Thanks to app integration via eWeLink, you always have everything in view – even on the go.

Info: The sensor supports ZigBee hubs that conform to the ZigBee 3.0 protocols, such as SONOFF iHost, NSPanel Pro, ZB Bridge Pro, ZBDongle-E, and Home Assistant ZBT-1. Additionally, it is theoretically able to connect with any ZigBee hub developed according to the ZigBee 3.0 protocols, like Echo 4th Gen and SmartThings Hub V3. This broad compatibility makes it a versatile and adaptable device for integration into smart home systems.
