Translating the state of entities

· One min read

The method for integrations to provide translations for states of its entities under other integrations, for example to translate an integration's sensors has changed.

Integrations should no longer use custom device classes together with a strings.<platform name>.json file. Instead, entities should set the translation_key property on an entity and include that translation_key in the integration's strings.json.

Pointing to translations via the translation_key property is currently only supported for entities with a unique_id.

The following example strings.json is for a Moon domain sensor entity with its translation_key property set to phase:

{
"entity": {
"sensor": {
"phase": {
"state": {
"new_moon": "New moon",
"first_quarter": "First quarter",
"full_moon": "Full moon",
"last_quarter": "Last quarter"
}
}
}
}
}

For more details, see the translation and entity documentation.
