All energy battery out counted as self consumption. #129

I have no solar yet, and all energy leaving the battery is accounted for as self-consumption, instead off showing simulated export to the grid.

Is this because the calculation for this needs solar generation present, any way I can work around this?

Do you mean in the energy dashboard?

Yes.

I think I have circumvented it now by creating 2 template sensors:

fake solar power production: 1W (updating each minite)

fake grid export power: 1W (updating each minute)

Then 2 integral helpers on that to get energy in kWh

Added the fake grid export energy as export sensor on the battery_sim

Added the fake solar energy as solar in energy dashboard, and now it seems better:

Hope today to have a full charge/discharge cycle to see if the numbers add up.

Ah I see. Interesting problem. I'm not sure if that is something I can fix within the battery sim itself. Glad you found a work around.

Actually, I think that is a bug in the energy flow card plus, not a problem in the battery simulation. I'm a back-end developer and I can read many sorts of programming languages, but I have no experience at all in building this type of targets and lack a development environment for it, so I can't build and test the change myself. However if I am not mistaking EiNSTeiN already has a fix for this.

Screenshot was of native energy dashboard.

In the meantime my real battery arrived. (still waiting on grid connection to get upgraded to 3 phase before connecting it)

This component was really helpful in getting a feel for sizing and cost analysis. Thanks again
