smartmeter-austria-energy 1.4.6

Connect locally to a Kaifa smartmeter of an Austrian energy provicer

Smartmeter Energy Austria

Library for connecting to Austrian Smart Meters of Salzburg Netz, TINETZ and EVN Retrieves the data from the M-BUS connector using a serial to USB converter.

Only tested on a Kaifa MA309 and Salzburg Netz (Salzburg AG). Some technical informations: The device uses Wired M-Bus (RJ 12) at 2400 baud. (1 start bit, 8 data bits, 1 parity bit, even, 1 stop bit. Communication is push only, every 5 seconds.

Usage

1. Install this package pip install smartmeter_austria_energy
2. Connect to your inverter using the correct COM port and fetch the data. Possible COM port settings: /dev/ttyUSB0, eg. using Linux COM5, eg using Windows

from smartmeter_austria_energy.supplier import (SUPPLIER_SALZBURGNETZ_NAME)
from smartmeter_austria_energy.smartmeter import(Smartmeter)

def main():
    supplier_name = SUPPLIER_SALZBURGNETZ_NAME
    key_hex_string = "-- this is your key --"
    port = "COM5"

    smartmeter = Smartmeter(supplier_name, port, key_hex_string)
    my_obisdata = smartmeter.read()

    print(f"RealEnergyIn: {my_obisdata.RealEnergyIn.ValueString}")
    print(f"RealEnergyOut: {my_obisdata.RealEnergyOut.ValueString}")
 
if __name__ == '__main__':
    main()

Script was tested on Linux (Ubuntu, Debian, Raspberry OS) and Windows (Windows 10, Windows 11).
