Read DLMS.python From meter

Hello Mikko
I'm interested in experimenting with DLMS/COSEM protocol I'm using Gurux.DLMS.Python example for readout data from meter

~/Downloads/Gurux.DLMS.Python-master/Gurux.DLMS.Client.Example.python (master ✘)✭ ᐅ python main.py
GuruxDlmsSample reads data from the DLMS/COSEM device.
GuruxDlmsSample -h [Meter IP Address] -p [Meter Port No] -c 16 -s 1 -r SN
-h host name or IP address.
-p port number or name (Example: 1000).
-S serial port.
-i IEC is a start protocol.
-a Authentication (None, Low, High).
-P Password for authentication.
-c Client address. (Default: 16)
-s Server address. (Default: 1)
-n Server address as serial number.

-g "0.0.1.0.0.255:1; 0.0.1.0.0.255:2" Get selected object(s) with given attribute index.
