When creating scenes from the UI, every single attributes of entities and every entities linked to a device a saved in the scene, even when it doesn’t make sense.
Examples:
- Read-only attributes (e.g. light effect list): Not relevant when restoring a scene, obviously
- Entities with unknown/unavailable states
- Button entities (“Warning: Integration button does not support reproduce state”)
Besides giving errors when trying to restore those states, it makes them difficult to edit in YAML.
