I am trying to set up a simple automation in HA, not Node Red. Automation is to turn a light on when a door opens but only when it's dark.
I thought that using a condition of sun, after sunset, before sunrise would achieve this but it does not work. I did read that below horizon is a better way to go but I couldnt see this option in any of the parameters.

I'm supposed to respect my elders, but it's getting harder and harder for me to find one now.

You can use a state condition for the sun, below horizon.

There might also be a blueprint for this, but I threw a slightly more advanced version together for you. It'll turn a light on to 80% when the door is opened (Fading up over 2 seconds).

Then turn the light back off 5 minutes after the door is closed. Fading down over 20 seconds.

alias: Light - On with Door
description: ''
mode: restart
trigger:
- platform: state
entity_id: binary_sensor.door_living_room_1
from: 'off'
to: 'on'
condition:
- condition: state
entity_id: sun.sun
state: below_horizon
action:
- service: light.turn_on
data:
brightness_pct: 80
transition: 2
target:
entity_id: light.living_room_lamps
- wait_for_trigger:
- platform: state
entity_id: binary_sensor.door_living_room_1
from: 'on'
to: 'off'
for:
hours: 0
minutes: 5
seconds: 0
- service: light.turn_off
data:
transition: 20
target:
entity_id: light.living_room_lamps

I made the same mistake the first time I tried creating a sun condition. The documentation actually covers this scenario as it's caused by way before/after are handled from/to midnight:

https://www.home-assistant.io/docs/scripts/conditions/#sun-condition

Note that if only before key is used, the condition will be true from midnight until sunrise/sunset. If only after key is used, the condition will be true from sunset/sunrise until midnight. Therefore, to cover time between sunset and sunrise one need to use after: sunset and before: sunrise as 2 separate conditions and combine them using or.
