In this video I walk through the three Lovelace modes in Home Assistant: auto-generated mode, storage mode, and YAML mode. Auto-generated is what you’ll see on 0.84+ by default—Home Assistant takes your entities and automatically drops them into cards, and when you add new entities it keeps building the UI for you. The big catch is you can’t really edit it from the UI or from files, because it’s meant to be maintained automatically. If you want full control, I show how to switch into storage mode by hitting the three dots and choosing “Configure UI,” then “Take control.” Nothing visually changes at first—Home Assistant just copies the auto-generated layout and makes it editable. Storage mode is the only mode where the frontend editor is available, and I also show how to use the Raw Config Editor to paste in an existing Lovelace config. The important limitation: storage mode won’t allow includes, secrets, or comments—those get removed or will error. Finally, if you need includes/secrets/comments and prefer file-based editing, I show how to enable YAML mode by setting `mode: yaml` under `lovelace:` in configuration, restarting, and then managing everything in your text editor. In YAML mode, the “Edit UI” option is disabled, so you’re committing to files-only editing.
