To be honest, I have no idea how/why I got SceneControllers for some (not all) my Fibaro modules. MCV has also not been able to figure it out. I’m not actually using them and have hidden them.
I trigger scenes by just using the status of the S2 switch as with any other switch.
It is parameter 41 for setting the scene functionality on an FGD211. Parameter 14 sets the type of switch being used.
