Some Hue lights, connected via Z2M ecosystem, support gradient scenes, that can be applied to the light during HA scene activation. One of these lights would be Philips Hue Signe with up to 5 colors gradient.
Such lights expose the light.x and select.x entities to the HA, where select.x entity allows you to select and apply the gradient scenes. When applying the select.x scene to the light, light won’t be turned on automatically, so if we only add this entity to the HA scene, light won’t go on. But if the light was on while scene was applied, indeed the correct colors will appear (according to the gradient scene selected in the select.x entity)
To have full functionality, we also need to add the light.x entity for the same light to the scene, that will turn the light on, but when we do that, HA scenes editor will popup ALL the light options to the scene config. When we apply the scene later, Hue won’t take select.x gradient scene into consideration, but rather single color from light.x config, which was picked up by HA during scene creation in the UI.
A request is to allow HA scene editor, to only set the on/off state for the light.x entity, without adding all the color configs to the yaml file.
Currently we must exclusively use YAML editor to manually remove all other options from the light.x and only keep the state: on there. If we later want to update some colors for other lights in the scene UI, all the entities are populated again with the full configs, destroying our yaml manual work.
