Feel free to use some of my code for more effects:https://github.com/GlennGoddard/Lights https://www.youtube.com/watch?v=RyhVeMgjnR4
It would be awesome if you could submit these effects as a PR to the ESPhome GitHub repo. The existing effects are pretty limited which is why I stopped using it for LED strips, switched to WLED. ESPhome has it’s benefit in that you can do more with a node than just the lights whereas WLED is purely for the LED strip so having extra effects would sway the decision a little more towards ESPhome.

Hello! I recently added my 1st WLED set up and like it!
That is yaml for ESPhome, nothing to do with WLED. The effects in WLED are better than what you will find available for ESPhome.
