The Integration Quality Scale scores each integration based 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.
Suggestions for changes can be done by creating an issue in the architecture repo.
This integration passes the bare minimum requirements to become part of the index.
- Satisfy all requirements for creating components and creating platforms.
- Configurable via
This integration is able to cope when things go wrong. It will not print any exceptions nor will it fill the log with retry attempts.
- Satisfying all No score level requirements.
- Connection/configuration is handled via a component.
- Set an appropriate
SCAN_INTERVAL(if a polling integration)
PlatformNotReadyif unable to connect during platform setup (if appropriate)
- Handles expiration of auth credentials. Refresh if possible or print correct error and fail setup. If based on a config entry, should trigger a new config entry flow to re-authorize. (docs)
- Handles internet unavailable. Log a warning once when unavailable, log once when reconnected.
- Handles device/service unavailable. Log a warning once when unavailable, log once when reconnected.
- Operations like service calls and entity methods (e.g. Set HVAC Mode) have proper exception handling. Raise
ValueErroron invalid user input and raise
HomeAssistantErrorfor other failures such as a problem communicating with a device.
Falseif appropriate (docs)
- Entities have unique ID (if available) (docs)
This is a solid integration that is able to survive poor conditions and can be configured via the user interface.
- Satisfying all Silver level requirements.
- Configurable via config entries.
- Don't allow configuring already configured device/service (example: no 2 entries for same hub)
- Discoverable (if available)
- Set unique ID in config flow (if available)
ConfigEntryNotReadyif unable to connect during entry setup (if appropriate)
- Entities have device info (if available) (docs)
- Full test coverage for the config flow
- Above average test coverage for all integration modules
- Tests for fetching data from the integration and controlling it (docs)
- Has a code owner (docs)
- Entities only subscribe to updates inside
async_added_to_hassand unsubscribe inside
- Entities have correct device classes where appropriate (docs)
- Supports entities being disabled and leverages
Entity.entity_registry_enabled_defaultto disable less popular entities (docs)
- If the device/service API can remove entities, the integration should make sure to clean up the entity and device registry.
- When communicating with a device or service, the integration implements the diagnostics platform which redacts sensitive information.
Best of the best. The integration is completely async, meaning it's super fast. Integrations that reach platinum level will require approval by the code owner for each PR.
- Satisfying all Gold level requirements.
- Set appropriate
- Support config entry unloading (called when config entry is removed)
- Integration + dependency are async (docs)
- Uses aiohttp or httpx and allows passing in websession (if making HTTP requests)
- Handles expired credentials (if appropriate)
Integrations which are part of Home Assistant are not rated but marked as internal.
