Parameter 14 is the level when the switch is “On”. As @zavex said, if the switch is “Off”, the level is controlled by Parameter 15 (and SetLevel does not work with that as yet). I was attempting to do level/color for a black series dimmer and it did not work when the switch was off (color would work, level would not). There is some hope though (per the response below):
Keeping that this will happen
