ITEAD had started to expand from WiFi and RF433 capable Sonoff home automation devices into Zigbee smart home solutions in recent months with the launch of products such as Sonoff ZBBridge WiFi to Zigbee gateway and a TI CC2531 based Zigbee USB dongle preloaded with firmware compatible with Zigbee2MQTT.
But so far, they had only one Zigbee node, namely Sonoff BASICZBR3 Zigbee power switch. More options are now available with the launch of four Sonoff SNZB Zigbee sensors and switches working with the company’s ZBBridge.
Key features of the four new Zigbee sensors & switches:
- SNZB-01 Zigbee wireless switch
- Touch button with single, double press and long press support
- Battery – 3V (CR2450)
- Dimension – 43x43x16mm
- SNZB-02 Zigbee temperature & humidity sensor
- Unnamed temperature and humidity sensor
- Battery – 3V (CR2450)
- Dimension – 43x43x14mm
- SNZB-03 Zigbee motion sensor
- Built-in PIR sensor with 6m range and 110°viewing angle.
- Battery – 3V (CR2450)
- Dimensions – 35x39x28mm
- SNZB-04 Zigbee wireless door/window sensor
- Magnet + sensor
- Battery – 3V (CR2450)
- Dimensions
- Magnet – 32×15.6x13mm
- Sensor – 47x27x13.5mm
All four devices are powered by a CR2450 coin cell battery and you’ll get a notification once the battery level drops below 10% in the mobile app. Which mobile? The usual eWelink app for Android or iOS which also supports integration with IFTTT. If you prefer open-source firmware, it may take more time, or never happen, as while we’ve reported on Zigbee open-source firmware, most of the work is based on TI CC25xx chips, and Sonoff Zigbee sensors are all likely based on Silicon Labs EFM32 Zigbee MCU like it is for their ZBBrigde gateway.

ITEAD Studio now offers a useful Zigbee ecosystem with a WiFi to Zigbee gateway, power switch, power socket, and battery-powered sensors that can control your devices or send alerts based on temperature and humidity readings, whether motion is detected, or a window/door is opened/closed. The Zigbee switch allows the user to control device by the press of a button without having to start the mobile app.
The just-launched Sonoff SNZB devices are also really affordable with pricing ranging from $7.99 to $9.49.
