Not able to get analysis of telegram

Hi spacemanspiff2007,
I'm not able to get an analysis of telegram but don't know whats wrong.

Receive following log:
[2023-01-28 10:53:01,675] [sml ] INFO | Starting V1.2.2

[2023-01-28 10:53:01,801] [sml ] INFO | Shutting down ...

When I make a cat on /dev/ttyUSB0 I see there are telegrams comming in.

Because I have an EasyMeter energy meter, I use following config-section for port:

ports:
- url: /dev/ttyUSB0   # Device path
  timeout: 30        # Seconds after which a timeout will be detected (default=3)
  baudrate: 9600
  parity: E
  stop bits: 1
  byte size: 7

Thanks for your effort,
Hardy

No error message in stdout or stderr? Is this the complete log?
Something is really strange - I would have expected that at least an error message

[harry7922]

That's all, no error or something else.
Example of telegrams coming from enery meter - if this could help:

/ESY5Q3DA1024 V3.04
1-0:0.0.0*255(<Number_of_energy_meter>)
1-0:1.8.0*255(00012385.6846316*kWh)
1-0:2.8.0*255(00030329.7409047*kWh)
1-0:21.7.0*255(000210.04*W)
1-0:41.7.0*255(000100.15*W)
1-0:61.7.0*255(000142.61*W)
1-0:1.7.0*255(000452.80*W)
1-0:96.5.5*255(80)
0-0:96.1.255*255(1ESY<ID_of_energy_meter>)

Thanks,

Hi,
I setup IDE and debugged.
Here debugger got an exception

And this is the data will look like:

I'm sorry that my programming skills are not yet as good to understand the issue.
But maybe this will help you to know whats wrong in my case?

Thanks and regards,
Hardy

I think you are trying to read a DSMR meter, but I am not 100% sure.
This is the wrong software for you, you need a dsmr-to-mqtt bridge or use a dmsr integration for your home automation software.
This software is used to read sml based meters which is a binary protocol.

Nonetheless it shouldn't just quit without any message ...

Shame on me!
I'm sorry you were absolutely right. Seems I was confused by the different types of smart meter interfaces.

Thanks for your help.

Best,
Hardy
