Hi,
apologies if there is an existing thread about this but I couldn’t find one. I am running HA .55 on a RPI 3 in a virtual environment. I am bug free at present but I did have a problem with configuration file permissions on ‘known_devices.yaml’. I changed the ownership from ‘root’ to ‘homeassistant’ which solved the problem.
Some of the files have ‘homeassistant’ as the owner and some have ‘root’. I don’t know why they ended up this way and I was wondering if there is any significance and if I should change them all to ‘homeassistant’.
