ESPHome RGB-LED Rainbow effect

When you say "Import this effect in your light module" do I copy and pate the code into an addressable_lambda section, or can I take your file and put it in a folder and then reference it by name? I have two strips I would like to use with this rainbow.

@Phando There are multiple ways:

• Using a header file would work.
• If it's just two lights, you could directly include it in their definitions I guess.
• I have multiple files with this content like the one above (but other effects of course) in a directory (led/effects) in esphome. On my light definition I do

light:
  - platform: rgb
    # other naming and stuff
    effects: !include_dir_merge_list led/effects/

That way all my effects are available on all my RGB light strips.

Thanks for the info! I am new to esphome. I have one light that is two light sections. 36 leds in total. Your other rainbow code is beautiful (on device). I can’t wait to see this one.
