Hi - I maintain a project that is available as an add-on for HassIO, and now there is an issue for a specific user. To troubleshoot it, I’ve done two things:
- Made a new “dev” label for the docker image, with a fix/additional logging - How can the user use this label, and not the regular versioned label that is described in the config.json of the Add-on.
- There is an environment variable / config value that controls logging levels, but to use this through HassIO - I must define it in my config.json (yes?) - is there a way to configure extra settings or environment variables, without cluttering the settings presented to the user?
The documentation does not describe how to troubleshoot on end-user setups. There’s a lot about local development, but I think I’m past that step … 
Mike.
