SNZB-04 Door and Window Sensor - Zigbee 3.0

The SNZB-04 from SONOFF is a sensor. This sensor detects whether a door or window is open or closed. You can easily attach the sensor to the wall with the included double-sided tape or you can put it on the table, for example. The sensor runs on a CR2032 battery, however this is not included.

Zigbee

Because the SNZB-04 works on Zigbee 3.0, you need a Zigbee hub. The suitable Zigbee hub from SONOFF is the ZB Bridge-P. The advantage of Zigbee over Wi-Fi is that it is specially designed for home automation and therefore consumes less energy, among other things. The SNZB-04 works as a Zigbee end device.

eWeLink

This SONOFF sensor can be configured using your Android or iOS smartphone through the eWeLink app. The eWeLink app allows you to view the measurements from your SONOFF sensors anywhere, including remotely. In addition, it is possible to set up scenes that are automatically activated at certain values. With a scene you can easily switch one or more devices on or off, for example you can turn on the lights and close the blinds (if you have connected them to SONOFF smart switches).
