L+G E450 Netz Burgenland unknown DLMS structure

[rooneyaut]

I've installed the latest smartmeter-datacollector v1.1.0 on my Raspberry Pi and connected an MBUS-USB-Adapter to my E450. The data from Netz Burgenland is encrypted with DLMS/COSEM regarding to their mail. These are the settings specified from Netz Burgenland:

Baud: 2400
Parity:  Even

Here is my datacollector.ini

[reader0]
type = lge450
port = /dev/serial/by-id/usb-Prolific_Technology_Inc._USB-Serial_Controller_BEA:n114J20-if00-port0
key = 6E3272357538782F443F442B472D4B64

[sink1]

[sink0]

Here is the debug output:

I hope that helps, I am trying to get the data from my E450 for several months now and then found this software and it looked really nice, but it's not working for some reason.

Hi @rooneyaut I tested your data samples both with the DLMS-Translator from Gurux (part of this software: https://www.gurux.fi/GXDLMSDirector) and with a test in our software. However I've had no success parsing the data.

DLMS Translator provides the following output:

<HDLC len="6C" >
<!-- Logical address:103, Physical address:127 -->
<TargetAddress Value="33FF" />
<SourceAddress Value="1" />

The HDLC layer seems to be valid, so it is no baudrate or serial transmission issue. But it can not decipher the data somehow. I do not why... Maybe the key is wrong. Or you could ask in the Gurux forum https://www.gurux.fi/forum providing a data sample and your key.

Have you made any progress so far? If you modified your key in the message above, it would explain a lot why I couldn't parse it.

I suspect however that your data does not contain any OBIS codes, only values and you need to setup the OBIS push setup yourself. See https://github.com/scs/smartmeter-datacollector/issues/34#issuecomment-1221298300
