Help needed to read vr_71 SensorData1 (and similar)

I already tried the generated file VR_71.26.vr_71_configuration.json from ebus-ebusd-configuration project - but I didn't get it to run.
Thing is here, I can link the channel, polling request is sent but the OH item doesn't get a value.
The underlying ebusd shows a correct value.

What's missing?

@csowada Could you point me into the right direction?
As I said, polling requests are generated but no values in openhab are arriving...

It seems that the folling error message is related to the problem:
[.csdev.ebus.core.EBusEbusdController] - Error while parsing ebusd response: :ERR: invalid numeric argument

What could I do to get futher?
I'm using the most current version of ebusd, ebus-binding and openhab...
