Hi,

Hi,

There are a few things that might cause this, but in this case, you need to change the client address. You can add -c parameter. I don't know what value your meter is using for High authentication. You need to ask this from the meter vendor. If it's taking a long time to get a reply, you can try values 1, 2, 3, 17, 18, 19.

Thank you, it works now.

Thank you, it works now.

Also, how can I move the command line parameters in to the python script so I don't have to enter the parameters via the command line. Thanks

Hi,

Hi,

You need to modify the client example for your needs.
