Periodic lights

periodic_lights.yaml

blueprint:
  name: Periodic lights
  description: "Dim and adjust color temperature of lights progressively throughout the evening (RGB bulbs probably won't change temperature). This is indexed to the midpoint between sunset and sunrise and fit to a sin function, so the midpoint will be minimum brightness and midpoint +12hr will be maximum brightness. The midpoint can be offset by a fixed amount if lights are too dim or bright at the desired time."
