I finally used [iemguts/receivecanvas] because it turned out to be 100% reliable - no matter how many devices I have connected.
The lastest cyclone update still didn't work for me.
I must have used an older version [MouseState] - the newer one is in small letters [mousestate].
That doesn't make it work any better in my case with the kiosk plugin.
Alexandres [else/button] works also well but had the problem that I couldn't find out how to lable it.
As soon as I put it behind another canvas for labeling it didn't work anymore - switching on is fine but it didn't switch off anymore unless it's on top.
