SONOFF ZigBee Bridge is the heart of smart home that allows you to remotely manage a variety of ZigBee devices and sensors for home monitoring and monitoring purposes, and allows you to create smart scenes to let Wi-Fi and ZigBee smart devices communicate to access a smarter home and control them all with the eWeLink APP. It maximizes efficiency for up to 32 connected subdevices that are ZigBee-based switches, plugs and security sensors. SONOFF BASICZBR3 Wi-Fi Smart Switch, S31 zb Lite smart plug, SONOFF SNZB-01 Wireless Switch and sensors such as SNZB-02 temperature and humidity sensor, SNZB-03 motion sensor and SNZB-04 wireless door/window sensor can be connected to the Bridge to allow you to make different scene couplings. As for more supported devices, the Bridge can also work with a single smart switch, temperature and humidity sensor, motion sensor, wireless door/window sensor and water sensor certified by ZigBee Alliance. Pair all subdevices with one tap, faster than wi-fi pairing. It supports adding a camera to the Bridge or subdevices, convenient to view your home on one of these devices. Can also order Alexa or Google Home to control your home with voice control.
