Is there any way to transfer Home Assistant to a new computer or hub without re-pairing all your devices?
When you talk about ‘re-pairing’, are you referring to WiFi, Zigbee, Z-Wave devices or something else?
Yes, but how you do it depends on how you installed HA.
From the other thread I’m still not exactly sure how you installed HA but I assume it was HAOS.
If that’s the case (and remember I don’t use it so I could be wrong on some detail) but all you should need to do is do a full backup of your system.
then install a blank new install of HAOS on your new machine.
Then in the onboarding it should give you the option to restore from the backup of the old machine created in step 1.
that should bring everything over and I think that includes all add-ons (now apps) and their configuration. So everything paired before should be there afterward.
I think…
I installed HAOS on my Optiplex computer using Ubuntu. I am just thinking of upgrading or recovery in case of unforeseen problems. What I am wondering is whether I can back up to an external drive for recovery from a catastrophe. I wouldn’’t want to have to re-pair all my devices and re-enter all my automations, scripts, etc. Thanks for you help.
In principle, that’s what a backup is for - you can restore the backup of one instance to a newly installed one.
The question above still stands, though.
WiFi devices are not an issue (there is no ‘pairing’) and the ‘pairing information’ for Zigbee and Z-Wave devices is normally held on the ‘router’ itself - but the ‘dongle’ might be on a different USB port on the target machine which can be adjusted on the new system after a restore.
