PaperUI: Switching Hue Bulb with Homematic Switch

I am trying to link a Homematic Switch (State Channel) to a Hue dimmable bulb (Brightness Channel) just using Paper Ul to switch the hue bulb to its last brightness when the state of the homematic switch changes its state to ON. I’m no sure if this is even possible by just linking the channels, or do I need a rule to accomplish that?
Any help to clarify this is appreciated.
Take care
Ingo
