Comment out half your automations. Run the config check. If it passes, then the issue is in the commented part. If it does not pass it is in the uncommented section.
Keep halving the section that contains the error.
You should be able to narrow it down from 256 automations to 1 in only 8 halvings.
Good idea, but with over 130 yaml-files it’s going to take a while
I must do this when the house is more or less idle. It’s going to be late tonight…
I’ll rename the yaml-files to filename.yaml.ignore or something like that. Or is there a way to skip complete folders with yaml-files? Renaming a folder to folder.ignore will probably not work (?)
When I ‘#’ one line, I’m NOT loading, automations, or sensors, or, scripts, …
I’ll start with that. At least I know whether it’s in automations or in packages; and then go from there.
