Actions

An action is something Ambience does when a scene is applied, for example: turn on a light, set a cover position, send a notification, or run a script. Each action calls a Home Assistant service, passing it a target (which entities to act on) and any parameters the service needs (brightness, colour temperature, cover position, and so on).

You can put as many actions in a scene as you like. When the scene wins, Ambience runs all of them.
