SONOFF ZBBridge Smart Bridge Zigbee 3.0 APP, Smart Home Wireless Remote Control, Work with Alexa, Google HomeSONOFF 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 control, and allows you to create smart scenes to make smart devices communicate Wi-Fi and ZigBee to access a smarter home and control them all using the eWeLink app. It maximizes efficiency for up to 32 connected sub-devices which are ZigBee-based switches, outlets and security sensors. SONOFF BASICZBR3 Wi-Fi smart switch, S31 zb Lite smart socket, SONOFF ZigBee wireless switch and sensors like temperature and humidity sensor, motion sensor and wireless door/window sensor can be connected to the bridge to give you the ability to create various scene connections. As for supported devices, the bridge can also work with certified one-button smart switch, temperature and humidity sensor, motion, wireless door/window sensor and water sensor by ZigBee Alliance. One-click pairing of all sub-devices, faster than Wi-Fi pairing. It allows adding a camera on the bridge or sub-devices, convenient to view your home on any of them. Can also command Alexa or Google Home to voice control your home.Make Zigbee and Wi-Fi devices interactWhether your Wi-Fi or Zigbee devices are supported, now you can control them together on the e-welink app via the bridge.Features:Remotely control ZigBee and Wi-Fi devices on the eWeLink app.Quick one-click pairing of all sub-devices to be connected.Long-distance ZigBee signal transmission covers almost your entire home.Compatible with a wide variety of SONOFF ZigBee smart plugs, switches, wireless switches and sensors for smarter scenes.Hands-free control of connected devices with Alexa or Google Home.Support sharing the device with your family to control it together.Group devices and access to control them through the app home page instead of sub-devices.View your home by adding an on-deck camera or sub-device.Works with other smart devices certified by ZigBee Alliance.
