There are discussions, but no feature request. So I take it with one of the comments. I use English Home Assistant, am native in a second language, my wife in a third. While I prefer English, my kids prefer our country’s native language, my wife hers.
While I can set up Dashboards with the cards they need, they would like to have the interface in the preferred language, not in English. To my kids, English is a foreign language. Would be great to have a smart interface for smart home to deliver in the preferred language by device. And I am sure, there are legions of users out there to then help if translations miss or fail.
