Energy Meter for House consumed energy

[doncuco]

Hello,

i have a routine, that loads my battery based on tibber prices and the loss of the battery.
It calculates the price and blocks the Battery from discharging when tibber is cheaper. This is in node red.

then I have created a calculation routine for HASS to calculate the real Battery discharge price based on charging costs from grid incl. battery loss and the solar input.

At the winter time this has no issues, but right now when the weather gets better the problem is, that this does not take care of the solar forecast.
It simply tries to fully load the battery.
My idea is to calculate a target SOC based on the expected solar forecast, the expected house consumption based on the last days.
But my problem is that the sonnenbattery does not give us an energy meter output of any powermeter, especially of the house consumption that I need.
The energy dashboard is calculating this and this might also be an option. But I only have power values for the battery.
For solar and grid I have energy meter values.
Has anyone of you solved that?
What is the best way? using an integral?

Thanks for your help.

You need to use the Riemann sum to calculate the energy integral see here
Also look into EMHASS. It is complex but very good at energy management.
