The Sonoff Zigbee 3.0 USB Dongle is a perfect Zigbee stick for all your Zigbee devices. It works out of the box with Home Assistant and Zigbee2MQTT or ZHA. You can also update it with the latest firmware so that it supports more devices and has a longer range.

Steps to upgrade the Sonoff Zigbee 3.0 USB Dongle Plus

First, you have to make sure that you put your USB dongle in bootloader mode. You can disassemble the stick easily and click on the bootloader button while you put the stick in your USB port on your computer.

After that, you can download the firmware from Koenkk’s GitHub page.

You need the flash programming software from the Texas Instruments page to flash the firmware to the USB dongle.

After you downloaded the firmware and the Flash Programming Software, you can continue to flash the firmware to your USB dongle.

When the flashing is completed, you can re-assemble the stick and put it in your Home Assistant server to use. make sure that you turned off your Home Assistant server before you insert the stick. After you’ve inserted the stick, you can turn on your Home Assistant server and configure it in Zigbee2MQTT or ZHA.
