Any thing we have ready in our home-assistant.core should be put in branches.txt. As we self-use plugwise-{description} for PRs add it as such.
As we don't want 'push-by-push', for now (until we make this a PR mandatory repository) you'll have to manually trigger the workflow from actions
The github actions on this repo run daily + will self-commit to the repo. As such 'auto'-triggering should be used with care.
Hence the above comment to implement a PR-only trigger (besides the daily one) and not react to 'all' commits.
If you want to prepare a PR text add a {description}.md file (as in the description from the core branch plugwise-{description}) it will generate a link to that markdown file.
