$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.

Sonoff Zigbee 3.0 USB Dongle Plus Board

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.

  1. I’m just curious why it needs a “heatsink” type housing, considering ZigBee chips don’t run hot at all.

      1. With shipping it comes to 40usd to send to the Netherlands. Maybe it will be available on aliexpress, that would save a lot on shipping

  2. I purchased one of these Zigbee Dongles and have not been able to get it working. I can see the dongle with ‘lsusb’ :

    Bus 001 Device 007: ID 10c4:ea62 Cygnal Integrated Products, Inc.

    Plugging in an original siliconlab device gives the following response:

    Bus 001 Device 007: ID 10c4:ea60 Siliconimage CP210x

    So neither windows nor linux can properly handle this device. Hence my dongle is not recognized as a UART serial adapter and therefore neither Homeassistant nor zigbe2mqtt will discover it. I suspect that the CP2102N is not original Siliconlabs silicon but maybe a counterfeit one.

    The Sonoff/ITEAD customer support is unable to help. They directed me to the silicon lab driver. However AFAIK the silicon lab driver is part of the mainline Linux.

    This linux cp210x.c driver does not support the device id 10c4:ea62 
    see excerpt from the source code below:

        { USB_DEVICE(0x10C4, 0xEA60) }, /* Silicon Labs factory default */
        { USB_DEVICE(0x10C4, 0xEA61) }, /* Silicon Labs factory default */
        { USB_DEVICE(0x10C4, 0xEA63) }, /* Silicon Labs Windows Update (CP2101-4/CP2102N) */

    I wonder if others have experienced the same issue or have any advice other than to return it?

      1. Thanks for the hint. Unfortunately in the forum you pointed out, no solution is available. I added a note with my conclusion there.
        I still have no response from Sonoff/ITEAD, they simply went dark on me. It would be good to know if this issue is just a temporary production issue and fixed now.
