Hi
We have two L+G E450 meter which push data in different structures. I use Gurux.DLMS.Python in my software to parse this data, however it only works with one of the two meters.
I used the translator tool of Gurux Director to parse and inspect the raw data to further analyze the problem.
First the output of the meter data my Gurux based software is able to parse:

As you can see the second example uses a "flatter" hierarchy in the structure. Do you know that behavior or the reason for this different structure? Can you give me a hint how to use the Gurux DLMS Python parser software to be able to parse also this second data structure?
See this Github issue for more context information:
https://github.com/scs/smartmeter-datacollector/issues/21
Thank you very much in advance.
Sincerly,

Hi,
Hi,
Can you add raw hex trace from the push bytes so I can verify this?
BR,
Mikko
Hi Mikko
Hi Mikko
Of course, however the data is encrypted and I cannot write the key here since it is from a meter of someone else. Therefore I'm not sure if the raw data is useful for you in any way.

Hi,
Hi,
You are right. Because data is encrypted it doesn't help me.
Can you encrypt it with GXDLMSDirector? Select DLMS translator and set correct settings for the Ciphering tab. Then select "Messages" tab and add this data and translate it. Add decrypted output here so I can verify it.
BR,
Mikko

-------------------
Please note, it is not the same sample as in the first message from me. However, the data structure is similar.
I could copy and past the three block data values into the Pdu section of the translator and get the structure like in my first request.
Thanks and best regards,

Hi Mikko
Hi Mikko
I just wanted to kindly ask whether you came to a conclusion about this different data structure I received from this smart meter. I sent you the keys by E-Mail. Is there a way I could use the Gurux.DLMS.Python software to parse also this structure?
Best regards,
raymar
Hi,
Hi,
Can you also send the client and server system title to me by email?
I can't decrypt the data without that information.
BR,
Mikko
