Support for Migrating Away from SmartThings

[jflowers]

Is it possible to perform a backup from a SmartThings hub to restore to zigbee2mqtt?

[puddly]

Not with this package. You can, however, use a Zigbee packet sniffer with Wireshark and join any device to your SmartThings hub to capture all of the relevant network information.

With that, you can manually fill in a zigpy backup JSON, restore it to a Z-Stack radio, and finally take a Z2M-compatible backup to replace Z2M's coordinator_backup.json with (make sure to also update Z2M's config with these same settings, it will erase your settings if the two don't match up):

    },

        },

        "stack_specific": {},

    }
}

If you want to try this, feel free to post the packet capture here and I can try to help out.

thanks, need to go research zigbee packet sniffer now

[puddly]

Most Zigbee radios support packet capture, though most also require alternate firmware (with the exception of Silicon Labs EmberZNet radios). You can use any Conbee, Silicon Labs radio, or even a CC2652 if you have a TI dev kit or another way to re-flash the bootloader. Or a dedicated nRF52840 stick.

I like the nRF52840 as a standalone sniffer, relatively cheap and easy to set up with wireshark
