Scenes and what they set
The four built-in scenes and what each one is for.
The four scenes
Reading is 2,340K at working brightness. Wind Down is 1,820K at about a third. Night is 1,800K at the bottom of the range. Campfire is 1,800K with the output lower still, for a room you are not working in.
Editing a scene
Scenes are editable in the app. Changing one changes it everywhere it is used, including in any automation that calls it.
