Title says it all really.
Any changes made to configuration.yaml in the folder ~/umbrel/app-data/home-assistant/ are wiped each time the Umbrel node is restarted.
And any text added to configuration.yaml in the sub-folder ~/umbrel/app-data/home-assistant/data are ignored by Home Assistant.
Can anyone point me towards some info about what the proper procedure is re: configuration.yaml? Many thanks, D
Hi!
I’ve just started using Home Assistant. Great app but that’s bad news if the configuration gets wiped out when you restart. So you had to configure everything again?
There’s a workaround – make all the edits you want to configuration.yaml and make a duplicate of that file called configuration.yaml.template … everytime Umbrel/HA reboots, configuration.yaml is overwritten by the contents of configuration.yaml.template … I don’t know why this is necessary, but its working for me.
Now if anyone has managed to get Sonos integration working in Umbrel HA (possibly a firewall issue?) hit me up! Banging my head against that one right now.
My solution to all my problems:buying another RaspPi4, install directly Home Assistant.
Much simpler.
There is always that approach 
I’ve mirrored my Umbrel HA on an ancient MacMini running HA w/ VirtualBox VM … which creates other issues (painfully slow reboot times).
Thanks for the hint.
Could you guide me please how to edit the files? i’m having trouble with it and can’t access the file. docker is new to me
by the way. i have sonos integration working. combined sonos beam and sonos era 300 for my tv setup.
