Backup of HUSBZB-1 not working

[jds11111]

I (tried to) follow the instructions on home assistant to back up the coordinator: disable zigbee, ssh into machine, shell in docker. Then used the suggested command, and got the following errors:

~ $ docker exec -it homeassistant bash
bash-5.1# python -m zigpy_znp.tools.network_backup /dev/serial/by-id/usb-Silicon_Labs_HubZ_Smart_Home_Controller_C13017E9-if01-port0 -o network_backup.json

  File "/usr/local/lib/python3.9/site-packages/zigpy_znp/api.py", line 395, in request
    response = await response_future
asyncio.exceptions.CancelledError

During handling of the above exception, another exception occurred:

Looks to me like it does not find the dongle, but I double checked the id of the device. Also tried rebooting the HA machine after disabling the coordinator. As a check I also tried downloading from the new Sonoff Zigbee 3.0 Dongle Plus, but received the same error.

You need to use bellows to back up a SiLabs radio.

Puddy has a build that will create a compatible network backup:

pip install zigpy-znp 'git+https://github.com/puddly/bellows@puddly/open-coordinator-backup'

Backup; bellows backup -d /dev/serial/.... > backup.json

Restore to new TI stick: python -m zigpy_znp.tools.network_restore /dev/... -i /path/to/backup.json

Thanks. I think that there is something wrong with the order of your Backup command ("backup" should follow the device), but there was still an error. Maybe I should try to do it from a linux box, instead from inside a docker container. Anyway, apparently this is not the place to discuss backing up the SiLabs dongle. Thanks for the pointers!

If you're doing a backup to migrate coordinators, this is as good a place as any to discuss. What's the error you receive? Did you disable the ZHA component before running any of these commands so that ZHA isn't concurrently using the serial port?
