Ebusd with Esera ECO305

[e1l52]

I am trying to get ebusd to work with an Esera ECO305 adapter and my Vaillant heating system (5 ebus nodes : aroTherm Plus heat pump, VRC720, VR921, VR71, aguaFlow). But I have failed so far. It looks like the automatic configuration is not working. The scan takes an extremely long time. And in the end it doesn't recognise any device.

I'm really lost. Does anyone have an idea?

Solved with the help of Esera's excellent support.
If someone gets the same problem: it is important to call the address with the prefix enh :

ebusd -d enh::
