Rgb turn colors with script.

[Tokatubs]

I am controlling an dmx controller from Elka via knx. 

Added to Mosaic for turning colors. Working like a charm. 
Now i want to create something that turns the colors during the day. 
Scheduler would work, but i guess thats a little bit 1980. 
Anyone have a good way to change the colors randomly..

something like this would do

Code:

math.randomseed(os.time())
value = math.random(0,16777215)
grp.update('RGB', value)

Of course i did not get this going on my first try.
Added to a script, but nothing happened to the GA.
Where do i put in the transsision time between the random value calculates.

This script just generate a random RBB value each time it runs, nothing more. It use the 3byte RGB object.
