This wireless door/window sensor is essential for knowing who is coming in and out of your home, so it is most often used as part of a smart security system.
SONOFF SNZB-04 is a ZigBee two-in-one wireless door/window sensor that can be put on your door or window to tell you with an alert notification if your door or window is opened or closed, adding an extra layer of security to your home. The sensor provides you the possibility to create a scene linkage of ZigBee and Wi-Fi devices. Both the opening and closing status of the door/window are synced on your mobile phone. Works with SONOFF ZigBee Bridge so you can set a scene to get your hallway lighted immediately when the door is opened. The camera function can be enabled on the sensor page in the eWeLink APP, which also allows you to view clearly who enters your home; you can even frighten the stranger with the two-way audio function. Its application can also extend to wide areas like drawers, garage doors, blinds, etc. Just stick it anywhere and connect and it is always safe even if you don’t keep watch on it. Share the sensor with your family to give them an ability to quickly control and monitor your home together. Simple installation. Peel and directly stick it on the place or object.

What is Zigbee? Zigbee is an (IEEE 802.15.4-based) wireless communication standard particularly well-suited for Wireless Personal Area Networks (WPAN) applications, such as smart home lighting control. The standard has longer range than Bluetooth and is cheaper and less power consuming than WiFi. The standard has become popular and is used i.a. by Ikea and Philips HUE.
Zigbee supports mesh networking and can thus transmit data over long distances by transmitting through a network of intermediate Zigbee devices to reach more distant devices.
If you are already a user of the Zigbee universe, you can easily connect our Sonoff Zigbee products with these. Products with Zigbee open up a whole new world, of control options. But you probably already know about these if you are allready a Zigbee user.
