Submit your work

:::tip Always base your Pull Requests off of the current dev branch, not master. :::

Submit your improvements, fixes, and new features to Home Assistant one at a time, using GitHub Pull Requests. Here are the steps:

  1. From your fork's dev branch, create a new branch to hold your changes:

    git checkout -b some-feature

  2. Make your changes, create a new platform, develop a new integration, or fix issues.

  3. Test your changes and check for style violations.
    Consider adding tests to ensure that your code works.

  4. If everything looks good according to these musts, commit your changes:

    git add .

    git commit -m "Add some feature"

    • Write a meaningful commit message and not only something like Update or Fix.
    • Use a capital letter to start with your commit message and do not finish with a full-stop (period).
    • Don't prefix your commit message with [bla.bla] or platform:.
    • Write your commit message using the imperative voice, e.g. Add some feature not Adds some feature.
  5. Push your committed changes back to your fork on GitHub:

    git push origin HEAD

  6. Follow these steps to create your pull request.

    • On GitHub, navigate to the main page of the Home Assistant repository.
    • In the "Branch" menu, choose the branch that contains your commits (from your fork).
    • To the right of the Branch menu, click New pull request.
    • Use the base branch dropdown menu to select the branch you'd like to merge your changes into, then use the compare branch drop-down menu to choose the topic branch you made your changes in. Make sure the Home Assistant branch matches with your forked branch (dev) else you will propose ALL commits between branches.
    • Type a title and complete the provided template for your pull request.
    • Click Create pull request.
  7. Check for comments and suggestions on your pull request and keep an eye on the CI output.

:::info If this is your first time submitting a pull request, the CI won't run until a maintainer approves running it. Just wait, a maintainer will eventually come by and approve it. :::
