Integrating Total House Load into Energy Dashboard

Hi all, I’m an absolute beginner to Home Assistant and would like to get the amount of money saved due to the solar energy I produced. I wasn’t able to find what I was looking for, but maybe I’m just too inexperienced to look at the right places… To integrate my inverter and battery I’m using the Modbus configuration from here: GitHub This repository provides some .yaml files for home assistant. - GitHub - snitzelweck92/homeassistant_alphaess_modbus_tcp: This repository provides some .yaml files for home assistant. This creates the entities to fill the energy dashboard. The sources look like this: image What I’m missing is something like ‘total house load’ in the overview, which also calculates the notional total costs/income for the day (so far). If adding that to the sources is somehow restricted or difficult to do as a first thing, adding a card showing that would be sufficient as well. Can anyone give me a hint on how to get started to integrate that thing?
