Multi lingal

[shannonhochkins]

There's been a request to ensure we can support multiple languages, I've done some initial experimentation and all looks possible to retrieve translations from homeassistant over websockets which means this will be a relatively easy (but time consuming) feature to add!

Ideas, multiple hooks to retrieve translations, localise functions as well as the ability to fetch more translations by category.

Roadblock - There's a websocket hook called frontend/get_translations, however this doesn't return everything, for some reason the front-end requests translations through this hook as well as a file, in a structure like: http://homeassistant.local:8123/static/translations/en-[hash].json and currently there's no way to retrieve the has name dynamically to fetch it.

I've created a discussion ticket - home-assistant/frontend#20760
