I'm curious what type of Statistics monitoring system you aiming for @poVoq. I have ordered a 3.7kw panels + special type inverter for direct heating of a boiler and a secondary boiler/other item. And i am intrigued what the monthly differences are in kWh generation and would like to track those. Only I have no idea what I can hook up between the panels and inverter to log.

The hybrid inverter I got has a ethernet connection that can be connected to Home Assistant: https://github.com/nathanmarlor/foxess_modbus

Not sure yet how I will analyse that exactly, but it might be nice to automatically publish some stuff to a website via it.

I'm exporting from Home Assistant to Prometheus and visualize that using Grafana.
