I am using Sumeru verde energy meter.
I am used Gurux.DLMS.Python to read the value of energy meter.
Where I can enter high level authentication key in the code ?
Hi.
Hi.
You need to change the client address also.
client = GXDLMSClient(True, 0x30, 0x1, Authentication.HIGH, bytes("Password"), InterfaceType.HDLC)

Sir, I am not understand
Sir, I am not understand which python file change these setting.
I am run the main.py file.
Hi,
Hi,
Add parameters -a High -P "PASSWORD".
