Convert RGBW 1byte in to DT8 object

[khalil]

Hello Dears,
I want to create a script that convert 4x1byte objects in to 1 DT8 object.
but how to avoid multiple write to the DALI: like if the 4 RGBW objects changed this will trigger 4 DT8 Commands to the DALI Bus!

Could you share a script considering this case.
