Hello,
I would like to create a DLMS client with gurux_dlms python library.I have already downloaded the source code on Github but i don't know how to use it.
Could I have some help please.
P.S I tried to follow the
P.S: I tried to follow the steps in topic "How to make DLMS client for smart meter." but i got several at the end.
Hi,
Hi,
Try to use the client example to read your meter. It will read all the data from the meter.
https://github.com/Gurux/Gurux.DLMS.Python/tree/master/Gurux.DLMS.Clien…
You need to give TCP/IP address and port number as a parameter like this:
python main.py -h HOST_NAME -p PORT_NUMBER

Hi thanks for your reply,
Hi thanks for your reply,
But my problem is how can I use the client example , I only found modules in this folder. I don't quite understand how it works and how can use it to read data from my meter.
Hi,
Hi,
The example client app reads all data from your meter. You can modify if for your needs.
Finst you need to install requirements like this:
pip install -r requirements.txt --upgrade
Then you can run the app as I described above.

Hello thanks for your reply,
Hello thanks for your reply,
I managed to install the requirements as you said but I still don't understand the app you are talking about.
This is what I have, below in the image after downloading the file from GitHub. Which file should I open to be able to communicate with my meter?
Hi,
Hi,
You can start the communication using command line parameters. They are something like this:
python main.py -h HOST_NAME -p PORT_NUMBER
If you download the GXDLMSDirector and play with that, you get a better understanding of the DLMS meters. They can be pretty complicated.

Hi thanks for your reply,
I understood what you have said , now I can start a communication using command line parameters. But I get some errors when I try to establish un public client, like this :

I use a "Kaifa AMD206D" meter.
Hi,
Hi,
At first, everything looks good, but the content of the second message that the meter returns is invalid and there is no reason for that.
Is this happening every time? Can you try to reboot the meter and connect after that?

Hi,
Hi,
Thanks you so much it's work.
Hi,
Hi,
Using command line parameters is really cumbersome. Is there another way to use the gurux_DLMS_client_example without going through the cmd.
Hi,
Hi,
You can use GXDLMSDirector to read your meter.
If you want to use Python, there are no other examples available at the moment.

Hi,
Hi,
You are using the ciphered connection. I belive that your block cipher or authentication key is invalid. You need to check what keys to use from the meter documentation or the vendor.
