Home Assistant Core 2026.6.0 DeviceRegistry async_get_device identifiers implementation

💡 Result:

In Home Assistant Core 2026.6.0, the DeviceRegistry.async_get_device method is deprecated [1]. This method was used to look up a device based on a set of identifiers or connections [2]; however, as of the 2026.6.0 release cycle and associated architectural changes, identifiers and connections are no longer unique across all of Home Assistant—they are only unique within the scope of a specific config entry [1][3]. Because a lookup by identifiers or connections may now match multiple devices across different config entries, the return value of async_get_device is considered ambiguous [1]. Key implementation notes for developers: 1. Deprecation: Developers are instructed to stop using async_get_device [1]. 2. Replacement: When the owning config entry is known, you must use scope-aware methods: - DeviceRegistry.async_get_device_by_identifier(identifier, entry_id) [1] - DeviceRegistry.async_get_device_by_connection(connection, entry_id) [1] These methods accept a single identifier or connection tuple along with the specific config entry ID to ensure an unambiguous lookup [1]. 3. Ambiguous Handling: During the deprecation period, async_get_device attempts to resolve ambiguity by preferring devices owned by the calling integration or by applying specific fallbacks, such as preferring a device whose config entry domain matches the looked-up identifier [1]. However, this behavior should not be relied upon for new development [1]. 4. Entity Context: If you are working within an entity, you should prefer using self.device_entry rather than performing a registry lookup [1]. These changes were part of a broader transition to restrict devices to a single config entry to improve reliability and registry performance [1][3].

Home Assistant device registry async_get_device_by_identifier config_entry_id 2026.6.0 source

💡 Result:

In Home Assistant, async_get_device_by_identifier is a method introduced in the device registry to provide a non-ambiguous way to look up devices [1][2]. Because device identifiers and connections are unique only within the scope of a specific config entry, the older method, async_get_device, was deprecated [1][3]. Using async_get_device_by_identifier (and the related async_get_device_by_connection) requires passing both the identifier tuple and the config_entry_id to ensure the registry returns the specific, correctly-scoped device [1][2]. This change is part of a broader architectural shift to enforce that devices belong to a single config entry [1][4]. While Home Assistant 2026.6.0 included various internal registry updates, the formal deprecation and the introduction of these scoped lookup methods were emphasized in developer communications following the 2026.6 release cycle [1][5][6]. Integrators are advised to replace calls to async_get_device with these scoped methods to avoid ambiguity and prepare for future breaking changes [1][3].

Home Assistant Core 2026.6.0 device registry DeviceRegistryDevices get_entry identifiers set implementation

💡 Result:

In Home Assistant Core, the DeviceRegistry.get_entry method is designed to retrieve a specific device entry based on provided identifiers or connections [1][2]. As of the current implementation, the method accepts an optional config_entry_id parameter to filter the results, allowing for precise lookups when multiple devices might share similar identifiers across different config entries [1][2]. The method is defined to accept optional sets of tuples for identifiers and connections: identifiers: set[tuple[str, str]] | None = None connections: set[tuple[str, str]] | None = None *, config_entry_id: str | UndefinedType | None = UNDEFINED When identifiers are provided, the implementation iterates through them and performs a lookup against the registry's internal mapping (_identifiers). If a match is found and a specific config_entry_id is provided, it returns the device entry associated with that config entry; otherwise, it returns the first matching entry found [1][2]. A similar lookup logic is applied to connections using the _connections mapping [1]. Key implementation details include: 1. Lookup Logic: The method prioritizes returning an entry that matches both the identifier/connection and the specified config_entry_id (if provided). If no config_entry_id is provided, it returns the first available entry from the set of matches [1][2]. 2. Return Type: It returns a DeviceEntry (or appropriate internal entry type) if a match is found, or None if no match exists [1][2]. 3. Integration: This method is used by higher-level methods like async_get_device, which serves as the public-facing API for retrieving devices by their unique identifiers or connections [3][4]. The identifiers parameter expects a set of tuples, where each tuple is structured as (DOMAIN, identifier), such as (serial_number_domain, serial_number_value) [5]. These identifiers are critical for ensuring that devices are correctly associated with their respective integrations and config entries within the registry [5][6].

Select a device after applying the config-entry filter.

When the two identifiers resolve to different devices, async_get_device() returns the first indexed match. The config-entry check then discards that device and update() returns without refreshing entities. Resolve each identifier separately, keep only candidates containing self.entry.entry_id, and add a regression test for this case.

device lookup in the relevant update flow so each identifier is resolved
separately, candidates are filtered to those containing self.entry.entry_id, and
the first eligible device is selected instead of discarding async_get_device()’s
first match. Add a regression test covering identifiers that resolve to
different devices and verify entities are refreshed from the
config-entry-matching device.
