Iskra MT174 historical data

Open romjer17 opened this issue 4 months ago • 1 comments

I would like to read historical data from the Iskra MT174 smart meter via Moxa RS485 to TCP converter. I have the following code.

from iec62056_21.client import Iec6205621Client

client = Iec6205621Client.with_tcp_transport(address=('192.168.225.11', 4001), device_address='62810711', password='00000000')
client.connect()

for data_set in client.standard_readout().data:
    print(data_set)

client.disconnect()

The code can connect to the meters and read some data.

As far as I understand, the address 1-0:1.8.0* contains the data I need, but I don't understand what date time this data refers to. The second problem is that I can't find how to read data for a specific date time.

Can someone explain it to me ?

Well... It depends 😄

So in your standard readout you get historical values from the last 15 months.

the last number in the obis us usually "not-used" (255). But if it is used it usually represent historical data.

So you have a bunch of datedata like DataSet(address='1-0:0.1.2*04', value='2506010000', unit=None) shows that the last obis code part = 04 is the monthly value at 2025-06-01T00:00

So the value: DataSet(address='1-0:1.8.0*04', value='0078600.749', unit='kWh') is the meter value for this timestamp.

This is not a full DLMS implementation so many things are left to the manufacturer to define.

If you want higher resolution than monthly you have to read the manual to see how to read it from a load profile.

You want to access the programming mode and then find out the commands to read the data.

For example in an EMH meter you need to read it like: R5: P.01(00401021200;10405191000).

It is probably P.01 you want to read. And you have to see what read command you need to use.
