I was thinking of something like this, thanks. Unfortunately brighten on my dimmer brightens not by one, but by 6%.
So, if I wanted to brighten in 1% increments I assume I will need to use a variable.
What are the advantages (if any) of defining 'Fade Up Exterior' as its own program and not just define the commands directly in the 'Almost Sunset' then block?
Also, what is the threading model of the ISY? If I'm in the middle of running Fade Up Exterior will other triggers continue to be evaluated and executed?
