It is simply a text file that you read with any text viewer. You can’t access that file from within the HA UI unless you have some way via the UI to access the actual text based yaml config files.
I have File Editor with which I can (theoretically) see and download home-assistant.log so I think I’m seeing the right log. Maybe I didn’t see all of it the first time because of some bug…
I use HA OS
How do I access the root of my OS file system? This pops up upon googling how to access /var/log. I suppose that’s what I’m looking for?
(btw @petro the HAOS (alternative way) section of it was what I was referring to earlier. Will I get any support in this forum upon attempting this?)
