Integration Manifest

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.

{
"domain": "hue",
"name": "Philips Hue",
"documentation": "https://www.home-assistant.io/components/hue",
"issue_tracker": "https://github.com/balloob/hue/issues",
"dependencies": ["mqtt"],
"after_dependencies": ["http"],
"codeowners": ["@balloob"],
"requirements": ["aiohue==1.9.1"],
"quality_scale": "platinum",
"iot_class": "local_polling"
}

Or a minimal example that you can copy into your project:

{
"domain": "your_domain_name",
"name": "Your Integration",
"documentation": "https://www.example.com",
"dependencies": [],
"codeowners": [],
"requirements": [],
"iot_class": "cloud_polling"
}

Domain

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: mobile_app. The domain key has to match the directory this file is in.

Name

The name of the integration.

Version

For core integrations, this should be omitted.

The version of the integration is required for custom integrations. The version needs to be a valid version recognized by AwesomeVersion like CalVer or SemVer.

Documentation

The website containing documentation on how to use your integration. If this integration is being submitted for inclusion in Home Assistant, it should be https://www.home-assistant.io/integrations/<domain>

Issue Tracker

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

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.

Built-in integrations shall only specify other built-in integrations in dependencies. Custom integrations may specify both built-in and custom integrations in dependencies.

After dependencies

This option is used to specify dependencies that might be used by the integration but aren't essential. When after_dependencies is present, set up of an integration will wait for the after_dependencies 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. For example, if the camera integration might use the stream integration in certain configurations, adding stream to after_dependencies of camera's manifest, will ensure that stream is loaded before camera if it is configured. If stream is not configured, camera will still load.

Built-in integrations shall only specify other built-in integrations in after_dependencies. Custom integrations may specify both built-in and custom integrations in after_dependencies.

Code Owners

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

Specify the 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.

{
"config_flow": true
}

Requirements

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: ["pychromecast==3.2.0"].

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:

pip install pychromecast==3.2.0 --target ~/.homeassistant/deps
hass --skip-pip

This will use the specified version, and prevent Home Assistant from trying to override it with what is specified in requirements.

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:

git clone https://github.com/balloob/pychromecast.git
pip install -e ./pychromecast
hass --skip-pip

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:

{
"requirements": ["git+https://github.com/issacg/[email protected]_connect#pycoolmaster==0.2.2"]
}

Custom integration requirements

Custom integration should only include requirements that are not required by the Core requirements.txt.

Zeroconf

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.

{
"zeroconf": ["_googlecast._tcp.local."]
}

Certain zeroconf types are very generic (i.e., _printer._tcp.local., _axis-video._tcp.local. or _http._tcp.local). In such cases you should include a Name (name), MAC address (macaddress), or Manufacturer (manufacturer) filter:

{
"zeroconf": [
{"type":"_axis-video._tcp.local.","macaddress":"00408C*"},
{"type":"_axis-video._tcp.local.","name":"example*"},
{"type":"_airplay._tcp.local.","manufacturer":"samsung*"},
]
}

Note that the name and manufacturer filters should be all lowercase and the macaddress filter should be all uppercase.

SSDP

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.

{
"ssdp": [
{
"st": "roku:ecp",
"manufacturer": "Roku",
"deviceType": "urn:roku-com:device:player:1-0"
}
]
}

HomeKit

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.

{
"homekit": {
"models": [
"LIFX"
]
}
}

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.

MQTT

If your integration supports discovery via MQTT, you can add the topics used for discovery. If the user has the mqtt integration loaded, it will load the mqtt step of your integration's config flow when it is discovered.

MQTT discovery works by subscribing to MQTT topics specified in the manifest.json.

{
"mqtt": [
"tasmota/discovery/#"
]
}

DHCP

If your integration supports discovery via dhcp, you can add the type to your manifest. If the user has the dhcp integration loaded, it will load the dhcp step of your integration's config flow when it is discovered. We support passively listening for DHCP discovery by the hostname and OUI. 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 DHCP data. It's up to your config flow to filter out duplicates.

If the integration supports zeroconf or ssdp, these should be preferred over dhcp as it generally offers a better user experience.

The following example has three matchers consisting of two items. All of the items in any of the three matchers must match for discovery to happen by this config.

For example:

  • If the hostname was Rachio-XYZ and the macaddress was 00:9D:6B:55:12:AA, the discovery would happen.
  • If the hostname was Rachio-XYZ and the macaddress was 00:00:00:55:12:AA, the discovery would not happen.
  • If the hostname was NotRachio-XYZ and the macaddress was 00:9D:6B:55:12:AA, the discovery would not happen.
{
"dhcp": [
{
"hostname": "rachio-*",
"macaddress": "009D6B*"
},
{
"hostname": "rachio-*",
"macaddress": "F0038C*"
},
{
"hostname": "rachio-*",
"macaddress": "74C63B*"
}
]
}

USB

If your integration supports discovery via usb, you can add the type to your manifest. If the user has the usb integration loaded, it will load the usb step of your integration's config flow when it is discovered. We support discovery by VID (Vendor ID), PID (Device ID), Serial Number, Manufacturer, and Description by extracting these values from the USB descriptor. For help identifiying these values see How To Identify A Device. 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 USB data. It's up to your config flow to filter out duplicates.

warning

Some VID and PID combinations are used by many unrelated devices. For example VID 10C4 and PID EA60 matches any Silicon Labs CP2102 USB-Serial bridge chip. When matching these type of devices, it is important to match on description or another identifer to avoid an unexpected discovery.

The following example has two matchers consisting of two items. All of the items in any of the two matchers must match for discovery to happen by this config.

For example:

  • If the vid was AAAA and the pid was AAAA, the discovery would happen.
  • If the vid was AAAA and the pid was FFFF, the discovery would not happen.
  • If the vid was CCCC and the pid was AAAA, the discovery would not happen.
  • If the vid was 1234, the pid was ABCD, the serial_number was 12345678, the manufacturer was Midway USB, and the description was Version 12 Zigbee Stick, the discovery would happen.
{
"usb": [
{
"vid": "AAAA",
"pid": "AAAA"
},
{
"vid": "BBBB",
"pid": "BBBB"
},
{
"vid": "1234",
"pid": "ABCD",
"serial_number": "1234*",
"manufacturer": "*midway*",
"description": "*zigbee*"
},
]
}

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.

{
"quality_scale": "silver"
}

IoT Class

The IoT Class describes how an integration connects with, e.g., a device or service. For more information about IoT Classes, read the blog about "Classifying the Internet of Things".

The following IoT classes are accepted in the manifest:

  • assumed_state: We are unable to get the state of the device. Best we can do is to assume the state based on our last command.
  • cloud_polling: The integration of this device happens via the cloud and requires an active internet connection. Polling the state means that an update might be noticed later.
  • cloud_push: Integration of this device happens via the cloud and requires an active internet connection. Home Assistant will be notified as soon as a new state is available.
  • local_polling: Offers direct communication with device. Polling the state means that an update might be noticed later.
  • local_push: Offers direct communication with device. Home Assistant will be notified as soon as a new state is available.
  • calculated: The integration does not handle communication on it's own, but provides a calculated result.
