Upgrade ConBee2 Firmware in HassOS

I used deConz in Home Assistant for the last 9 months and I discovered some crazy things in the way deConz is working. The strangest one is surely the gateway firmware update (for me a ConBee2): even if you are on a 1-year-old firmware, in Phoscon you always have the message "your version is updated".

The only thing to do to really have the latest firmware version is to use the manual upgrade process, which is working in home assistant even if the official documentation says no.

  1. First of all you need to know what is the device name of your zigbee gateway. The easiest way is on the docker startup. At the beginning is showing you the list of devices and the line with the "Serial" is your gateway one (mine is /dev/ttyACM1).
    [s6-init] making user provided files available at /var/run/s6/etc...exited 0.

    Path             | Vendor | Product | Serial     | Type
    -----------------+--------+---------+------------+-------
    /dev/ttyACM0     | 0x1CF1 | 0x0030  |            | ConBee II

    /dev/ttyAMA0     | 0x0000 | 0x0000  |            | RaspBee
    
  2. Stop the deConz Integration. You can do it on the interface... image.png NOTE If you have 'Watchdog' activated it may be better to disable it on the integration during this process. It could start the integration up unattended.
  3. SSH to hass (standard SSH, not the OS one).
  4. Start the deConz container to use the Gateway flasher binary. Here you should specify the device retrieved to step 1 and you should override the entrypoint which is configured to start the deConz app.
    docker run --rm -ti --privileged=true --device /dev/ttyACM1:/dev/ttyACM1 -v /dev/bus/usb:/dev/bus/usb --entrypoint /bin/bash homeassistant/aarch64-addon-deconz:6.8.0
    
  5. Download the latest firmware , if it is not already contained in the Docker image (folder /usr/share/deCONZ/firmware/).
    wget http://deconz.dresden-elektronik.de/deconz-firmware/deCONZ_ConBeeII_0x266b0700.bin.GCF
    
    NOTE The firmware in this example is the latest available released on 29/04/2021. If you have a different Gateway from Dresden Elektronik, you can find the firmware at the same URL image.png
  6. Upgrade the firmware with the following command
    GCFFlasher_internal -d /dev/ttyACM1 -x 3 -f deCONZ_ConBeeII_0x266b0700.bin.GCF
    
    The -d parameter correspond to the device name found on the first step. The -x parameter is the log level. With value 3 you should have lot of details The -f is where you should provide the firmware filename. Waiting only a few seconds and you should have the firmware upgrade message.

  7. Get back to the interface and start the integration as usual to bring back your zigbee network to normal.
