Sensor Triggered Light HA Automation Blueprint

sensor_triggered_light.yaml

blueprint:
  name: Door light after dark (manual control preserved)
  description: >-
    Turns a light on for a set time when a door opens, but only when the sun is
    below a configurable elevation. Never touches a light that was already on,
    and backs off if the light is turned off manually during the window.
    Re-opening the door during the window restarts the timer.
