Variable delay time, set within function
I was looking for a way to add a delay within a "While" loop in a function node,this apparently is harder than adding the classic Thread.sleep(1000) line.
So thanks to this flow, I can now start creating a function that dims up or dims down a value.
The aim is to compare the required value against a known state. Is the value is > then dim down over a number of step
if the value is < then dim up over a number of steps
