An automation can have multiple triggers and action logic can be branched using If/Then or Choose actions.
Here’s an example from the Community Cookbook
That example uses templating with trigger IDs, but it could be done with If/Then with Trigger conditions as follows:
description: "Turn on lights at sunset and off at sunrise"
trigger:
- id: 'on'
platform: sun
event: sunset
- id: 'off'
platform: sun
event: sunrise
action:
- if:
- condition: trigger
id: 'on'
then:
- service: light.turn_on
target:
entity_id: light.your_light
else:
- service: light.turn_off
target:
entity_id: light.your_light
mode: single
