Sonof | ZigBee | SNZB-04 | door and window sensor

The tool-less door/window sensor is essential for knowing who is entering and leaving your home and is therefore usually used as part of a smart security system. The sonoff SNZB-04 is a two-in-one wireless ZigBee door/window sensor that can be placed on your door or window to notify you with an alert if your door or window opens or closes, adding a layer added security to your door or window. The sensor allows you to create a scene link from ZigBee and WiFi devices. The open and close status of the door/window is synced to your mobile phone, so you don't have to worry about whether the door is closed or not. It is very useful and can help you turn on or off the light in action. Working in harmony with SONOFF ZigBee Bridge, you can set a scene to instantly illuminate your hallway when the door is opened. The camera function can be activated on the sensor page in the eWeLink app, which also allows you to clearly see who is entering your house. You can even scare the stranger into leaving your house immediately with the two-way audio feature. The application can also extend to large surfaces such as drawers, garage doors, blinds, etc. Installation is simple, you just have to glue the sensor.
