sma2mqtt

Command line tool that listens to the multicast Speedwire of a SMA Energy Meter/Home Manger 2.0 and writes the values to a MQTT server.

I'm using this in my home to read the power consumption/generation from a SMA Home Manager 2.0.

Use at your own risk.

Install:

pip install sma2mqtt

sma2mqtt --help

usage: sma2mqtt [-h] [--topic TOPIC] [--mqtt_client_id MQTT_CLIENT_ID]
                     [--mqtt_address MQTT_ADDRESS]
                     [--mqtt_port MQTT_PORT] [--mqtt_username MQTT_USERNAME]
                     [--mqtt_password MQTT_PASSWORD] [--no_mqtt] [--dump_data]
                     [--serial_nr] [--force_print_serial] [--print_offsets]
