Yes, I do mean the Action in the Then part, and my KPLs are properly recognized as 2486D units, but they don't have the 1-99% in the dropdown, just the 100% and 0%. My other dimmers do, however, have 0, 1, 2, ... 100% dropdowns.
In a Scene I am allowed to set the KPLs on level, but not in the Action after Then.
If it matters I am on a Mac.
