Setting up Toon integration

I’m unable to get the Toon integration to work.

I’ve edited the configuration.yaml to include the API keys, and followed all the steps in the documentation, but still when I try to add the integration it displays immediately:

The component is not configured. Please follow the documentation.

Is there any way to get some more debug information, because this message isnt helpful at all. I have no idea at which step it fails?

I think this turns out to be related to Umbrel, which I used to install HA.

Umbrel has a docker file that mounts configuration.yaml to another location. So all the lines I added to /config/configuration.yaml were ignored the whole time. And HA had no way for me to display the contents of the configuration it uses, so I had no clue it used a different one.
