Use with an M-Bus dongle such as this one.

A class for decoding HDLC and extracting OBIS fields. Requires python module crcmod (sudo pip install crcmod). NB: This is not a full COSEM parser, as the number of OBIS fields and their sequence is assumed to be as on a Hafslund meter.

Test output.

./aidon_test.py <port>
./aidon_test.py /dev/ttyUSB0

Forward to influxdb and Home Assistant. Forwarding to only one of them is possible. Just omit the influx* or hass* arguments.
Will generate sensors in Home assistant named sensor.aidon_*. Not done with a component, so these sensors will disappear on Home Assistant restart, and can't be renamed.
For InfluxDB, readings are placed in the provided database under voltage, current, power and energy, and key dev holds device name (which begins with aidon).

Parses preliminary/old protocol used by Hafslund.
