Python properties

The following app manifest properties are only required for apps using the Python runtime.

Python version

A string with the Python version the app was developed for. Currently the only supported version is 3.14.

{
  "id": "com.athom.example",
  // ...
  "runtime": "python",
  "pythonVersion": "3.14",
}

If the given version becomes outdated with the version(s) available on the Homey platforms, a newer version may be used to run the Homey app, which may result in incompatibility. When a new full-release Python version becomes available apps have about a year to update to the new version.

Python dependencies

To keep track of the dependencies of the Homey app, and to allow for checking compatibility with Homey platforms, any libraries added as a dependency through the CLI will be stored in the app manifest.

{
  "id": "com.athom.example",
  // ...
  "runtime": "python",
  "pythonDependencies": [
    "aiohttp>=3.13"
  ],
}

Editing the dependencies in the app manifest without running homey app dependencies install results in the app being bundled with outdated libraries.

Installing dependencies through other means than homey app dependencies install results in those dependencies missing in the bundled app. Always test your app by installing it or running it remotely if you have changed the dependencies, in order to see whether they are bundled correctly.

Additional properties

The following app manifest properties are optional but can be used to document extra information about your app. Most of this information will be presented to users in the Homey App Store.

Platform Local Required Features

An array of required features (nfc, ledring, speaker or matter) for platform local. Adding a required feature will make the app uninstallable on Homey Pros that do not have all the listed features. So only use this when the app will only function with the respective feature.

{
  "id": "com.athom.example",
  // ...
  "platformLocalRequiredFeatures": [ "nfc", "speaker", "ledring" ]
}

Contributors

An object with keys developers and translators. Each object in the developers or translators array must contain a name property.

/.homeycompose/app.json

{
  "id": "com.athom.example",
  // ...
  "contributors": {
    "developers": [
      {
        "name": "Alice the Wild"
      }
    ],
    "translators": [
      {
        "name": "Klemens Kohlmann"
      }
    ]
  }
}

Contributing

Perhaps some users want to show their appreciation for your hard work in the form of a small donation.

When adding one or more donation options to your app's manifest, a Donate button will appear on your app's page.

Donate buttons are only visible for non-verified developers.

/.homeycompose/app.json

{
  "id": "com.athom.example",
  // ...
  "contributing": {
    "donate": {
      "paypal": {
        // Will link to https://paypal.me/my_paypal_username
        "username": "my_paypal_username"
      },
      "bunq": {
        // Will link to https://bunq.me/my_bunq_username
        "username": "my_bunq_username"
       },
       "patreon": {
         // Will link to https://www.patreon.com/my_patreon_username
         "username": "my_patreon_username"
       },
       "githubSponsors": {
         // Will link to https://github.com/sponsors/my_github_username
         "username": "my_github_username"
       }
    }
  }
}

Bugs

Users can come across an issue in your app. Provide them with a bug URL, so they can quickly share their findings with you. An object with a property url that contains a link to your public bug/issue tracker.

/.homeycompose/app.json

{
  "id": "com.athom.example",
  // ...
  "bugs": {
    "url": "https://bitbucket.org/athom/com.athom.myapp/issues"
  }
}

Homey Community Topic

The Homey Community is a great place to share additional information about your app with your users and fellow developers. When the ID of the topic is provided, this shows a link on the App Store. You can get the ID from the topic's URL.

/.homeycompose/app.json

{
  "id": "com.athom.example",
  // ...
  "homeyCommunityTopicId": 1234
}

Source

If you would like to, you can add a link to your source code to allow others to view your code and maybe even submit a Pull Request. A string, starting with https://.

/.homeycompose/app.json

{
  "id": "com.athom.example",
