30 minutes before sun.sun below horizon


Maybe easy answer, but how can i set my automation that trigger the light on 30 minutes before sun below horizon? i use the enitity sun.sun

config is now?

condition: state
entity_id: sun.sun
state: below_horizon

what can i do to use this 30 minutes before below_horizon?

It is recommended to use the sun elevation attribuate as a trigger, rather than a time offset for this.
Simple reason is that, depending on the season, a time based offset might be too much or too little.

This is how I do it. I do 50 minutes beforehand, but that’s easily changed.
