Eltako "Baureihe 14 – RS485" (Enocean) Debugging

Hi,
I am a beginner in Home Assistant. I would like to try to migrate from another home automation system to Home Assistant.
Since my Eltako system is connected via a FGW14-USB via client socket (ser2net) and I cannot disconnect the FGW14-USB for testing purposes, I have a question for the experts among you: Is there any way to connect the Eltako Bus Integration via a client socket instead of USB?
