Yeah.. it was stock driver. I must have fat-fingered an entry at some point. I generally don't mess with the defaults... I normally explicitly set values, but because Simple Lighting doesn't ask, I guess it's grabbing the default.
And I just re-tried with Simple Lighting and the fixed default, and it works correctly now.
Yes, it does...but not when saved as a preference since the preference is looking for an integer. When you enter a decimal it is reverting to defining the preference as a string instead.
@mike.maxwell, it looks like there might be an issue with the transition time preference for Lutron dimmers. It is saving properly formatted decimals (0.1) as a string and then won't allow a setLevel command without a defined transition time. setLevel will accept 0.1 as the transition time but since 0.1 in the preference is reverting to a string, setLevel won't accept that.
