Recently, I saw this video showing a super easy way to update the firmware of a SONOFF Zigbee Stick: https://www.youtube.com/watch?v=-_bE_PbZwO0

Just for reference, this was the way I did it previously: https://nocin.eu/home-assistant-update-firmware-on-sonoff-zigbee-usb-dongle-p/

Following just a few notes and screenshots, doing a firmware update using the SONOFF Dongle Flasher.

1. Optional: Check current firmware version

and compare with latest firmware version here

2. Do a backup

3. Stop Z2M and install the SONOFF Dongle Flasher

Install https://github.com/iHost-Open-Source-Project/hassio-ihost-addon

Start Add-on, open WebUI and hit the connect button. If your dongle is not found, simply manually add the device. The rest is pretty self-explanatory.

4. If flash was successful, stop SONOFF Dongle Flasher and Start Z2M again. Check new version in Z2M WebUI. And that’s it.

Update 03.11.2025: There is now a much simpler way, check post here.

First, confirm that you have a Sonoff Zigbee 3.0 USB Dongle Plus. Go to Settings → Hardware → All Hardware → Search for Zigbee

Check your current firmware version:

Important: Stop Zigbee2Mqtt before flashing, as described in the docs!

Now let’s add the ZigStar repository: Settings → Add-ons → Add-on Store → Three dots → Repositories → Add https://github.com/mercenaruss/zigstar_addons

After that, install the Add-on for Texas Instruments CC2652P7 based radios.
