Automating Seasonal Lights

Configuration

I have been looking for a way to automatically change my outside light colors based on seasonal holidays.
I came across this post which appears to do exactly what I am looking for. However I need some clarification.

I need some assistance with it. What is the effect: ThanksGiving scan line? Where do I configure the ThanksGiving scan? What is the syntax?


id: holiday_thanksgiving
  name: Holiday Lighting - ThanksGiving
  icon: mdi:silverware-fork
  entities:
    light.livingroom_window_led:
      state: on
      brightness: 255
      **effect: ThanksGiving Scan**

It’s explained in the second sentence of the linked blog you posted.

This week, I started installing WS2813 individually addressable LEDs around the house. I made a few simple patterns containing colors relevant to Thanksgiving and Christmas.

It’s the name of a custom effect created by the blog’s author for “WS2813 individually addressable LEDs”.

Where are those configured? Where can I find syntax and examples?

All I want to do is slowly transition between three colors. Red, green, blue

Start

Red on for 5 seconds
Transition
Green on for 5 seconds
Transition
Blue on for 5 seconds

Goto Start

The blog’s author didn’t explain so you should ask him/her.

Use a scene’s transition option.
