I’m using a ConBee II Zigbee stick by Dresden Elektronik but switched from their own Phoscon/deCONZ software to the Home Assistant ZHA integration.
While I didn’t have any issues with my few Zigbee devices, today, I’ve noticed that there’s a newer firmware available for my ConBee stick. Usually, the firmware update is handled by the deCONZ software – which I’m not using anymore. Also, there’s a dedicated firmware update tool for Windows – which I’m also not using anymore.
However, their update instructions mention the use of Docker on Home Assistant. Which sounds exactly like the thing I need.
The instructions are compiled in the Home Assistant Forums and boil down to:
- Disable anything that uses the ConBee II. The forum post says deCONZ, in my case this means the ZHA integration. Settings –> Devices & Services –> Zigbee Home Automation –> ︙–> Disable
- Make sure you’ve enabled SSH access to the host via port 22222 or use the Advanced SSH & Web Terminal with safe mode disabled to connect to the base operating system
- Run this command:
docker run -it --rm --entrypoint "/firmware-update.sh" --privileged --cap-add=ALL -v /dev:/dev -v /lib/modules:/lib/modules -v /sys:/sys deconzcommunity/deconz - Follow the instructions. When it asks for the filename to use or download, you can find all available firmwares here. Only type the filename, not the whole URL – in my case this was:
deCONZ_ConBeeII_0x26780700.bin.GCF. Don’t panic during the firmware update. One step only ran up to 43% and then aborted, but it was automatically retried and finished successfully on the second try. If you don’t get a green “success” message, check all steps and try again. Also check the troubleshooting instructions. - Once you’re done, delete the Docker image to free up the space:
docker image rm deconzcommunity/deconz - Now you can enable the ZHA integration again.
