Backup your ZHA/HUSBZB-1 stick and even seamlessly migrate to a new stick without re-pairing!

Configuration Zigbee

You could, however, do it manually or make your own scripts where script for backup/restoring Silicon Labs based dongles could be made with “bellows” and script for backup/restoring Texas Instruments based dongles could be made with “zigpy-znp” which have CLI tools to backup and restore respectively.
