Iskra - MT382 - Stored Data

Hi community,

We are starting with DLMS with our Iskra meter.
The connection with a MT382 works perfectly with GXDLMS Director and we can get data from the meter.

I read the doc but I can't find the answer to theses questions :

1. So far we read and get the last data available from the meter with GXDLMS Director. In the futur we would like to make a code to get more data for this register (here Active Power+ in the picture). For exemple if we Read the meter at 12.00 can we get the date from 10.00 - 10.15 - 10.30 - 11.00 - 11.15 - 11.30 - 11.45 and 12.00 ?

Or do we need the read the meter every 15 minutes ?

2. Do you have an example of Python code that can help me to creat the same request than GXDLMS Director did for me :
