Does this give the following parameters?

today_generation today_exported today_purchase today_consumption

mgrom commented 2 years ago

From what I've seen there is: today_generation

Three others are not implemented

SofarSolar inverter doesn't have information about energy consumption, you need additional hardware next to your energy meter to measure energy consumption and return from/to grid and having those information and energy generated by inverter you can calculate all above in HomeAssistant or other home automation software.

There is no way to add all those parameters, because there are missing data (hardware limitation and different purpose).

The system already measures current and voltage from which we should be able to calculate power, apparent power , real power and powerfactor. I have seen this library which has implemented such a system with esp32.

EmonLib.cpp file explains the process of calculation and also I found a video in youtube with may also be related.

I hope this could be useful.
