RFX-sensor configuration in NodeRed

Hi,
I try to convert my RFXcom antenna message to MQTT.
First step is to setup the rfx-sensor node that reads the messages.
But I can’t get the rfx-sensor node to connect

Is it possible to both have RFXcom setup in the configuration.yaml file + the sensor setup in NodeRed ?

Anybode that can help me?
