Lurton Caseta Entities not available in Scene Editor

How come scene editor in the GUI only allows device selection and not all relevant entities? For example, I can add Hue bulbs and Zwave switches to a scene but not Lurton Caseta switches. I can do it from the YAML, but don’t know why it wouldn’t be in the GUI editor.

Was running into a similar problem (only with Insteon devices), and after reading about the Scenes Editor, I learned entities only show up when advanced mode is enabled for your user profile. Hope this helps!
