Hi there, I always used this command to upgrade my SkyConnect Zigbee usb key to the latest firmware.

universal-silabs-flasher --device /dev/ttyUSB0
flash --allow-cross-flashing --firmware skyconnect_ncp-uart-hw_7.4.2.0.gbl

when I try to do it with the latest firmware

universal-silabs-flasher --device /dev/ttyUSB0 flash --allow-cross-flashing --firmware skyconnect_zigbee_ncp_7.4.4.1.gbl

I get this error:

Traceback (most recent call last):
  File "/usr/local/bin/universal-silabs-flasher", line 8, in <module>
    sys.exit(main())
             ^^^^^^
ValueError: Unknown metadata version: 2, expected 1

I'm using HA Docker and the integration shows this error even if the zigbee key works correctly:

You could give the web flasher a go: https://home-assistant-skyconnect.netlify.app/firmware-update/

@ornate spruce I updated the firmware using the webinstaller but I still get this error in HA

any reason why?

disabling the zigbee mqtt container made the trick, thanks!!!

I was about to say that the error looks like totally being unable to communicate. But then your ZHA wasn't working... You were not using Z2M?

#

yes but I need to stop the Z2M container to be able to access that feature from the HA

#

That's because Z2M and ZHA are both integrations for Zigbee. And a coordinator can only talk with one at the same time. So to which are your devices connected to?

Aka, just delete the integration you don't use.

Z2M is an addon.

I use docker so no it's not an addon

#

zigbee2mqtt:
container_name: zigbee2mqtt
image: koenkk/zigbee2mqtt
volumes:
- "/opt/docker_ha/zigbee2mqtt:/app/data"
devices:
- "/dev/ttyUSB0"
environment:
- "TZ=Europe/Rome"
network_mode: host
privileged: true
restart: always

#

it's a container

#

Right but it's not an integration either. Addons are containers too. What makes rhem addons is that the images are special and can only run in HAOS.

#

so I can't update the firmware while zigbee2mqtt addon is running?
