This script works great for me. Is there a way of doing more of a flicker as well, where you can actually see the colours (like red, blue, green etc as some of my lights do on startup)
I did have to remove the top part and fill in the entity hardcoded, i guess i’m missing some critical yaml or indentation.
rainbow_light: # had to remove this (it's not indented now but it was before)
alias: rainbow light

entity:
description: The entity that will be rainbowed
example: light.study_room_light_1
