Problem: Homematic Virtual Key

Hello,

I have created two simple programs in the CCU, which are to be executed with a virtual button. Both programs work via the CCU and the weekly profile of the thermostats is switched over. But there is no reaction via openHAB.

Number Heizung ""
Switch Heizung_Arbeit			"Arbeiten"				{channel="homematic:HM-RCV-50:f52ed63e:BidCoS-RF:09#PRESS_SHORT"}
Switch Heizung_Frei				"Freier Tag"			{channel="homematic:HM-RCV-50:f52ed63e:BidCoS-RF:10#PRESS_SHORT"}
rule "Heizung"
when
    Item Heizung received command
then
	 if (receivedCommand==1) {
        Heizung_Arbeit.sendCommand(ON)
         
    }
    
    if (receivedCommand==2) {
        Heizung_Frei.sendCommand(ON)
    }
    if (receivedCommand==3) {
        Heizung_Urlaub.sendCommand(ON)
    }
end
Switch item=Heizung icon="" mappings=[1="Arbeiten", 2="Frei",3="Urlaub"]

Any ideas?

Greetings
Thomas
