Elegant way to simulate a transition?

[123 (Taras)]

Is there a better way to transform those 704 lines into, let’s say, < 10 lines?

The following isn’t more compact but can be applied to any light:

YAML Light Fader for light entities that don't support "transition"

Here is a script version of mrsnyds original work. Be advised this script is not identical to the original automation version. It uses the same algorithm but with several differences: Uses light not entity_id The option to specify the light(s) to be dimmed is named light instead of entity_id. The reason is because when you call a script using the script.turn_on service, you specify which script to turn on by setting the service’s entity_id option. This is the same name, so the script’s varia…

You can use the script in an action like this:

action:
  - service: script.light_fader
    data:
      light: light.lidl_e14_weiss
      transition: '00:15:00'

It calculates the optimal dimming interval based on the specified duration length. All credit goes to community member mysnyds. All I did was refactor it.
