I just installed the latest File editor, Version 5.4.0 and when I edit my configuration.yaml file, I get an error on the first ! substitution line (122 in the image here). If I comment that line out, the error moves to the next ! line (147). Comment line 147 and the error moves down to the next ! (148).
This is new- it just appeared today after upgrading the file editor.
If it were really an error, the configuration check before a restart would have flagged it. It doesn’t.
Same here saying !include not recognised in text editor, no matter what I do the system won’t reboot with that entry as home assistant says the configuration.yaml isn’t valid.
