So is 1 the LEDwiz divice number and 3 the LED number and 48 the intensity?
Yes
If you have RGB LEDS it will look a little different like this :
P1_BUTTON1,1,RGB,30,31,32,48,30,31,0,0,0,0
P1_BUTTON2,1,RGB,24,25,26,36,41,21,0,0,0,0
So add more lines like this :
P1_BUTTON1,1,RGB,30,31,32,48,30,31,0,0,0,0
P1_BUTTON1,2,RGB,17,18,19,48,30,31,0,0,0,0P1_BUTTON2,1,RGB,24,25,26,36,41,21,0,0,0,0
P1_BUTTON2,2,RGB,12,13,14,36,41,21,0,0,0,0
The Difference is you have three LEDS Numbers and three intensities per RGB Button
