Automation sun question

Configuration
1

Just did my first automation to turn on the front porch lamp and living room lamp (Lightify) which seems to work perfectly (at least when I trigger them, won’t know until tonight for sure).

My newbie question is: Do I need an automation to tell them to turn off in the morning?

#Automation
automation:
   alias: Turn on light when sun sets
   initial_state: True
   hide_entity: False
  trigger:
     platform: sun
     event: sunset
     offset: "-00:30:00"
  action:
     - service: light.turn_on
       entity_id: light.front_porch
     - service: light.turn_on
       entity_id: light.living_room_lamp

Yes you do! The reason being that sunset is a trigger that happens once a day, it is not a condition (in this context) so doesn’t automatically become false and magically reverse the “turn_on” calls - for simple cases that may be what you want but for more complex behavior it would be a liability so you need to explicitly tell the system to turn them off in a separate but very similar automation.
