Ok… is not simple to explain what I wanna do…
so, I have take some photo
I have a RGBWW controller that work with tasmota firmware (10 € on aliexpress :D)
I have connect 2 led strip, one RGB and una Cold White (about 6400k)
I have configured the controller as Generic because MagicHome settings was wrong with this device
and here you can see what I wanna do, normally for rgbw controller you have rgb pallette and a separate white control
I don’t want the white bar because I want that the center of pallette send to controller the command: color 000000ff instead to ffffff00
all the pallette must be converted because that I want is that the brightness of light must be managed by white strip
for example, I don’t want 55FF5500 for a light green, I want 00FF0055, the result is very most beautiful
directly on tasmota console you can turn on all 4 channel as you can see in photo
this is my actual configuration of HA
