Ok, where do I find that? My configuration.yaml contains all my components and there is no reference to packages. (I have been using HA for couple years and never created a package config)
Do you mean that somewhere in my configuration.yaml there a duplicate component like two sensors with the same name?
I checked and couldnt find any repeated components. I only use one yaml that contains all my sensors / switches / automations etc and I don’t break out anything into separate yamls like sensor.yaml. Is this my problem?
