Unable to read attribute =3 (1.0.94.91.0.255) IC=7 for Indian Metering, while I'm able to read attribute 3 for other Profile generic class

I'm using python lib.

Code:
inst_obj = GXDLMSProfileGeneric("1.0.94.91.0.255")
read_inst_profile = b''.join(secure_client.read(inst_obj, 3))
print("\n→ Read inst buffer:", read_inst_profile.hex())
ser.write(read_inst_profile)

DLMSDirector

Hi

I want to Know while reading data from meter do we need to apply the scalers to the meter data separately or else gurux will automatically apply scalers to the meter data.

Incorrect current values ​​for Landis Gyr E570 meter

Incorrect current values ​​for Landis Gyr E570 meter

Hi,
I wrote a function that should return current values, but instead of correct values ​​I get incorrect values, e.g. 0 values, or negative values.

What am I doing wrong?

Here is the function:

@app.route('/read/<int:meter_id>/<string:obis>', methods=["GET"])
def read_value(meter_id, obis):
print(f"DEBUG: Proba odczytu OBIS {obis} dla licznika {meter_id}")

reader = None
connection_key = None
