Since 0.92.0, every integration has a manifest file to specify basic information about an integration. This file is stored as
manifest.json in your integration directory. It is required to add such a file, except for custom components.
Or a minimal example that you can copy into your project:
The domain is a short name consisting of characters and underscores. This domain has to be unique and cannot be changed. Example of the domain for the mobile app integration:
The name of the integration.
The website containing documentation on how to use your integration. If this integration is being submitted for inclusion in Home Assistant, it should be
The issue tracker of your integration, where users reports issues if they run into one. If this integration is being submitted for inclusion in Home Assistant, it should be omitted. For built-in integrations, Home Assistant will automatically generate the correct link.
Dependencies are other Home Assistant integrations that you want Home Assistant to set up successfully prior to the integration being loaded. This can be necessary in case you want to offer functionality from that other integration, like using webhooks or an MQTT connection.
This option is used to specify optional dependencies that might be used. When
after_dependencies is present, set up of an integration will wait for the other dependency to be set up before being set up. It will also make sure that the requirements of
after_dependencies are installed so methods from the integration can be safely imported.
GitHub usernames or team names of people that are responsible for this integration. You should add at least your GitHub username here, as well as anyone who helped you to write code that is being included.
config_flow key if your integration has a config flow to create a config entry. When specified, the file
config_flow.py needs to exist in your integration.
Requirements are Python libraries or modules that you would normally install using
pip for your component. Home Assistant will try to install the requirements into the
deps subdirectory of the Home Assistant configuration directory if you are not using a
venv or in something like
path/to/venv/lib/python3.6/site-packages if you are running in a virtual environment. This will make sure that all requirements are present at startup. If steps fail, like missing packages for the compilation of a module or other install errors, the component will fail to load.
Requirements is an array of strings. Each entry is a
pip compatible string. For example, the media player Cast platform depends on the Python package PyChromecast v3.2.0:
Custom requirements during development & testing
During the development of a component, it can be useful to test against different versions of a requirement. This can be done in two steps, using
pychromecast as an example:
This will use the specified version, and prevent Home Assistant from trying to override it with what is specified in
If you need to make changes to a requirement to support your component, it's also possible to install a development version of the requirement using
pip install -e:
It is also possible to use a public git repository to install a requirement. This can be useful, for example, to test changes to a requirement dependency before it's been published to PyPI. The following example will install the
except_connect branch of the
pycoolmaster library directly from GitHub unless version
0.2.2 is currently installed:
If your integration supports discovery via Zeroconf, you can add the type to your manifest. If the user has the
zeroconf integration loaded, it will load the
zeroconf step of your integration's config flow when it is discovered.
Zeroconf is a list so you can specify multiple types to match on.
Certain zeroconf types are very generic (i.e.,
_http._tcp.local). In such cases you should include a name or MAC address filter:
If your integration supports discovery via SSDP, you can add the type to your manifest. If the user has the
ssdp integration loaded, it will load the
ssdp step of your integration's config flow when it is discovered. We support SSDP discovery by the SSDP ST, USN, EXT, and Server headers (header names in lowercase), as well as data in UPnP device description. The manifest value is a list of matcher dictionaries, your integration is discovered if all items of any of the specified matchers are found in the SSDP/UPnP data. It's up to your config flow to filter out duplicates.
The following example has one matcher consisting of three items, all of which must match for discovery to happen by this config.
If your integration supports discovery via HomeKit, you can add the supported model names to your manifest. If the user has the
zeroconf integration loaded, it will load the
homekit step of your integration's config flow when it is discovered.
HomeKit discovery works by testing if the discovered modelname starts with any of the model names specified in the manifest.json.
Discovery via HomeKit does not mean that you have to talk the HomeKit protocol to communicate with your device. You can communicate with the device however you see fit.
When a discovery info is routed to your integration because of this entry in your manifest, the discovery info is no longer routed to integrations that listen to the HomeKit zeroconf type.
Integration Quality Scale
The Integration Quality Scale scores an integration on the code quality and user experience. Each level of the quality scale consists of a list of requirements. If an integration matches all requirements, it's considered to have reached that level.
When your integration has no score, then don't add it to the manifest of your integration. However, be sure to look at the Integration Quality Scale list of requirements. It helps to improve the code and user experience tremendously.
We highly recommend getting your integration scored.
