The add-ons share the data path /share/zigbee2mqtt
so all your devices would be there.
Steps to use Edge (even if temporary):
- Stop the Stable add-on
- Backup your add-on configuration (add-on options)
- Make sure you disable the
Start on boot
for Stable add-on - Backup your data from
/share/zigbee2mqtt
- Use Samba or some sort of file sharing to copy it off the device (this is just for safety, not necessary) - Install Edge
- Set the Edge configuration / add-on options to the ones you got from the Stable one - Bonus you can enable the frontend using those settings (you would be missing the config if you overwrite all with your Stable config)
- Start the Edge add-on
I also have both Edge and Stable, and right now I’m using Edge because of the Frontend feature. The move was seamless.
