Multi-language Support for Blueprints

[Blackshome]

Describe the enhancement

Add support for translating blueprint names, descriptions, and other text elements using external JSON translation files. This would make blueprints more accessible to users in multiple languages.

English could be used as the default, with initial support for the most common languages, such as German, French, Spanish, and Dutch, and the option to expand to other languages as needed.

Example usage

Blueprint YAML could reference translations like this:

name: !trans blueprint.name
description: !trans blueprint.description


Translation files would be separate JSON files stored in a Gist or repository, for example:

translations_en.json – English translations

translations_de.json – German translations

Each JSON file would contain key-value pairs for all text strings used in the blueprint, such as names, descriptions, and messages.

Benefits:

Makes blueprints accessible to non-English speakers.

Supports multiple languages without duplicating the entire blueprint.

Updates to the blueprint automatically use the same translation keys.

The community can contribute translations in a structured way.

Example JSON format:

{
  "blueprint.name": "Sensor Light",
  "blueprint.description": "Sensor Light description here"
}


When the user selects their preferred language in Home Assistant, the system would pull the corresponding values from the appropriate JSON file.

This way, the name, description, and other text elements automatically update based on the selected language without needing multiple blueprints.

Current workarounds

You have to do a separate blueprint for each language. Crazy.

Anything else?

Not everyone speaks English, so it would be great to make blueprints accessible to everyone by allowing authors to provide translations.
