Hi

I tried by putting minutes and seconds = 0

obis = '1.0.94.91.0.255'
obj = GXDLMSProfileGeneric(obis)
start = datetime(2025,2,13,16,0,0,0)
end = datetime(2025,2,13,16,0,0,0)

resultV = reader.readRowsByRange(obj, start, end)
reader.showValue(3, resultV)

Getting same exception
Device reports. read-Write denied

How to read IP using client example? Please help

Hi Amlan,

You can't use the same start and end time. There is no data. Read your meter with GXDLMSDirector. Then select your meter and you can see the command line parameters so you can read your meter with the client example.
