I think we lost something in communication. This looks like it is all
done in software.

On these laptops, TUF and ROG, the LED effects are all done by the
keyboard EC. For the TUF series you can reference this
https://gitlab.com/asus-linux/reverse-engineering/-/blob/master/TUF-i2c_laptops/led-rgb

It's for this reason I first went with a single node using "n n n n n
n" input.
