Migrate from Conbee II to HASS SkyConnect (Silicon Labs EFR32MG21)

[jkaberg]

Hello everyone.

I recently purchased an SkyConnect since I for some time have had stability issues with my Conbee II.

I aswell as everyone else I guess aren't looking forward to re-pair 70 devices, therby I came by this tool/project which on paper seems to fit the bill, however I wanted to make sure before I proceed.

First of, is it at all possible? And what should I be aware of?

This functionality is built into the ZHA integration. Plug in your SkyConnect, click on "Configure", then "Migrate radio", and follow the instructions.

Make sure your Conbee is running the latest firmware, as older firmwares don't expose all of the information necessary to migrate the network completely.

Thanks for the reply @puddly! I'm using z2m currently, and thus not able to do that

But as I understand it I would need run;

1. Shutdown Z2M and any other software using the Zigbee device
2. zigpy radio deconz /dev/ttyUSB0 backup deconz-backup.json to backup the Conbee II
3. zigpy radio --baudrate 115200 ezsp /dev/ttyUSB1 restore deconz-backup.json to restore Conbee II config to EFR32MG21
4. Start up Z2M again

Does this require any additional packages such as bellows or other?

Off-topic here but see this discussion for migration for Zigbee2MQTT on migrations from Z2M to Z2M -> Koenkk/zigbee2mqtt#16478

Specifically, read these:

FYI, ZHA steps are in Home Assistant SkyConnect documentation -> https://skyconnect.home-assistant.io/zigbee-migration-selection/

Can confirm, still works like magic! Make sure you run the latest ConBee II firmware, the older version made a backup to but after a restore none of my devices worked through Z2M. Updated the firmware, another backup and restore and it worked! :)

Did this work for you? I would like to do the same. :)

[jkaberg]

Yes, like magic 😃

[newlund]

Nice! Thanks! :)

Any repairing needed?

[newlund]

I guess you ran the backup and restore in a separate linux pc? Probably easier than installing the zigpy-cli in hassio?

[jkaberg]

I run HASS in docker, and installed and ran zigpy on the host os (which is Ubuntu)

I don't know much about hassio

Note! If using Zigbee2MQTT then zigbee-herdsman which it depends on has a new experimental "ember adapter" made for newer firmware:
