Node-RED, RFXtrx node not connecting

I try to control my 433MHz wall plugs from Node-RED with a RFXcom.
Have added node-red-contrib-rfxcom and have set up the out-node.


From the HA hardware it looks like this:

But the rfx-light node will not get connected
Have removed the RFXcom from the HA Integration. To avoid having two units connected to one USB-unit.
What can be wrong?
