quick question I am starting of with lovelace now I know I am late but I want to find out how can I integrate the custom cards in the new lovelace configuration done all in the ui or frontend i.e. not using the ui-lovelace.yaml ?
Actually… my dirty little secret is I still use the yaml file and just cut and paste it whole into the raw editor and save. I only use the GUI editor for really minor stuff and then update the YAML.
well that’s weird! If it’s valid if you use yaml mode it should work fine in storage mode.
I did have some erors a few days ago with the folding-entity-row card… I could not save until I removed it and all references to it but that was an issue with that card that was fixed with an update so check all your custom-cards are up-to-date and valid as well.
But the official way to migrate old lovelace to storage mode is to copy and paste the ui-lovelace.yaml into the raw editor and save.
