RGB 3 x 1 byte absolute % dimming from KNX

[alexll]

Attach an event script to a 251.600 6 byte DALI RGBW object. The RGB part will control the color, W part will be the output brightness. Change R/G/B output addresses as needed.

Code:

value = event.getvalue() max = math.max(1, value.red, value.green, value.blue) mult = value.white / max red = math.round(value.red * mult) green = math.round(value.green * mult) blue = math.round(value.blue * mult) grp.write('1/1/3', red, dt.uint8) grp.write('1/1/4', green, dt.uint8) grp.write('1/1/5', blue, dt.uint8)

So I understand that, first, I have to convert/combine my 3 x 1 byte RGB objects + 1 byte dimming value into a 6 bytes object just to run this script, isn't it? Can you help me to do it? Thank you!
