# Time of Day Selector Blueprint
# Event-driven: sets an input_select when any configured time entity fires.

blueprint:
  name: "Custom: Time of Day Selector"
  description: >
    Event-driven time-of-day state machine.
    Maps a list of time entities to a parallel list of state names.
    When any time entity fires, the corresponding state is selected on the
    target input_select. Multiple entities mapping to the same state name
    produce OR-override behavior (e.g. sun_next_dusk OR a forced
    input_datetime — whichever fires first wins).

        The input_select entity whose option will be updated.
        Its options must include every state name listed below.

      description: >
        Ordered list of time entities. Each fires when its configured time
        is reached. Accepts input_datetime (time-only) and timestamp sensors
        (e.g. sensor.sun_next_rising, sensor.sun_next_dusk).
      selector:
        entity:

      description: >
        Parallel list of state names — one entry for each trigger above, in
        the same order. Each name must match an option of the target
        input_select exactly. Repeat a name to give that state multiple
        trigger sources (override / "whichever fires first" pattern).
