Hi together,
I installed the smartmeter binding today and connected my pi via an USB-IR-Reader to my DTZ541. According to the holley website, the DTZ sends in SML 1.04 (mode push) at 9600 baud.
Unfortunately I do not get the binding working.
When I set the Mode to D, baud to 9600 I’ll get the following errors:
2020-03-19 22:45:50.872 [WARN ] [.iec62056.Iec62056_21SerialConnector] - Exception while listening for mode D data message

If I do set the mode to SML, I’ll get an exception:

So I do not really know how to solve it or handle this issue.
I’ve tried to get the serial output to have a look at the raw data with
cat /dev/ttyUSB0 2>/dev/null | xxd -p -u -l 1420 -c 1420
The dump is like:

I would really appreciate any help 
Thanks in advance
