$9.90 SONOFF Zigbee 3.0 USB Dongle Plus works with Home Assistant

ITEAD has launched a new Zigbee dongle with the Sonoff Zigbee 3.0 USB Dongle Plus powered by Texas Instruments CC2652P wireless MCU which follows the company’s Zigbee 3.0 USB Dongle based on Silicon Labs EFT32MG21 Cortex-M4 microcontroller.

The dongle is pre-flashed with Z-Stack 3.x.0 coordinator firmware which enables ZHA in Home Assistant or Zigbee2MQTT compatibility.

ITEAD does not directly compare the “Plus” version with the earlier Zigbee 3.0 USB Dongle, but the new model should have a longer range, and possibly support more nodes with “21 direct children by default and up to 40 children”, while also writing “you can modify the relevant configuration to support up to 100 children”.

As a universal Zigbee USB stick, SONOFF Zigbee 3.0 USB Dongle Plus can be used with a Home Assistant gateway or other open-source platforms via ZHA or Zigbee2MQTT to locally control Zigbee sub-devices as explained in a short getting started guide. That means it can be connected to Home Assistant Blue or a Raspberry Pi board for additional Zigbee connectivity. Such gateway would support any compatible Zigbee devices include the many Sonoff “ZB” devices

The SONOFF Zigbee 3.0 USB Dongle Plus ships with an antenna and a user manual for $9.90. But note that supply is limited, and the USB dongle is only up for pre-order, with the second batch of dongles soon to be sold out, and orders after October 18 will only be shipped at the end of November.
