As far, a I know, I will carefully state, that something is wrong. The info I can remember from the time, I did my config, stated, that you can’t have 5 groups of rgbww lights on one controller. Max is 4. Same, like the phone app.
If that really is a problem, then your config will not work because of this.
I’m using scenes to change colors on my lights. And also this: GitHub - bokub/rgb-light-card: 💡 A Lovelace custom card for RGB lights
Works fine.
There is a thread about the configs here: Limitlessled - #25 by retrup
