Thanks! This looks pretty good. Couple asks.

1. Can you add a test that the channel is created if the option is present and then an onEventWithDoorState test too?
2. Add the channel to the README
3. Regenerate the translation file with mvn i18n:generate-default-translations for the new channel

Also make sure to run mvn spotless:apply clean install next time you build to fix the failing PR build check

@digitaldan All done. The DCO check still has a problem because it expects my GitHub username, not my real name which I also set in my GitHub profile. Is this a problem?

[digitaldan]

Personally i think its fine, but i'll let another maintainer chime in. Otherwise this LGTM, thanks for adding the tests and docs as well.
