Hi
Do you work with the above meter?
I am trying to code using python to read via TCP.
Thanks

Hi,

Do you have more information from this meter? Is there a DLMS label on the cover of the meter?
If there is you can read the meter. Just set the correct IP address and TCP/IP port. You should be able to get this information from the meter documentation.

Mikko

Hi,

I don't know if your meter is supporting DLMS. Is there a DLMS label on the cover of the meter?

You can try to connect using WRAPPER. Try with this:

python main.py -h 183.171.144.38 -p 5001 -a Low -P 33333333 -t Verbose -i -c 1 -s 1

BR,

Hi,

Thank you for your response. I have attached the meter picture that it supports DLMS.

I have also run the command as per advised but similar issue comes out, i.e. timeout.

Anything else that I need to look at?

Hi,

Can you get the trace from the send and received bytes in another application? If you can, I can check the correct settings for you.

My SRNM frame is this, 7E A0 08 02 FF 29 93 D1 80 7E. Can you confirm that below is correct?

C:\Gurux.DLMS.Python\Gurux.DLMS.Client.Example.python>python main.py -h 183.171.144.38 -p 5001 -a Low -P 33333333 -t Verbose -i -c 1 -s 1

And the reply would be below,
7E A0 21 29 02 FF 73 CC 61 81 80 14 05 02 01 20 06 02 01 20 07 04 00 00 00 01 08 04 00 00 00
01 0B C9 7E

Thank you in advance.
