The Solarmeter daemon is built upon the libabbaurora library to communicate with the ABB Aurora inverter. The daemon reads the energy production from the inverter, outputs a JSON formatted string and sends it to a MQTT broker on the network. From there, the data is forwarded into a time series database for permanent data storage and for visualization. The complete software stack consists of the following components, which need to be installed and configured separately:

• Solarmeter daemon with RS485 dongle for data readout
• Mosquitto MQTT broker
• Node-RED (MQTT client, PostgreSQL and optional email alerts)
• PostgreSQL with TimescaleDB and pg_cron extensions
• Grafana for visualization

The software stack is light weight in terms of necessary resources and runs on any SBC such as an Odroid C2/C4 or Raspberry Pi 3/4. Step-by-step instructions can be found at the Smartmeter sister project wiki pages. The Aurora converter needs to be connected to the host USB with a RS485-to-USB adapter like the one from Waveshare.

You can build and run the binary from docker. This is an easy solution if you want to run on a less setup (like synology)

docker -v $(pwd)/config.conf:/app/config.conf --device /dev/ttyUSB0 run jekkos/solarmeter:latest -c /app/config.conf
