Hey everyone, so i made a little progress.
The Entryway 8BKP is what is the load device for the "Front Porch Can Lights" and is a Insteon 8 Button Dimmer.
Basically what I have learned is that once a Scene is "On" ISY cant tell the Scene to DIM, unless I first turn the Scene OFF then, back ON.
What I attempted to do last night was to turn the Keypad Load Scene down, to dim the lights and that did work - i didnt have to first turn the lights off.
However, when the program ended, the lights went off, they didnt return back to 100%
I guess what I will do is setup a program that turns off the lights, adjusts the scenes then turns them back on. That will require the lights to shut off for 5-10 seconds each time.
I cant figure out how to get it to "gracefully" dim up/down w/o turning the lights off, which would be much more slick that the "on/off" method.
