Energy flow displayed incorrectly with house battery

[jeriox]

Describe the bug

We recently installed a hybrid inverter and a house battery. I included it into evcc and everything works fine. However, there is a quirk for our setup: we also have an old PV/inverter that does not support any reasonable method of communication, so it is not included in evcc. This leads to the following situation, where energy seems to appear out of nowhere (the old PV).

I was pleased to see that evcc renders the "?" to account for that mysterious energy. However, the proportions are off. evcc knows that 1.3kW are consumed, so I would expect the bar to account for that value, with around half of it (513W) marked in green as evcc knows the source of the energy. The other part labeled with the question mark should then be gray or a similar color. Also note how the small part of grid usage is displayed with a black color to the far right, but the icon (for whatever reason shrunk to a dot) is displayed between the sun and the question mark. I would also expect this to be aligned.

Steps to reproduce

1. Set up a hybrid inverter with PV and battery within evcc
2. Set up a grid meter within evcc
3. Connect another energy generator that is not included within evcc
4. Have the generator that is not included in evcc feed energy into the battery

What type of operating system are you running?

Linux

Nightly build

• [X] I have verified that the issue is reproducible with the latest nightly build

Version

evcc version 0.131.7

Just add an additional meter on your second inverter to sample its production correctly.

yeah thats what I'm planning to do long term, would still be happy to have it displayed correctly until then :)

@jeriox can you please post the state json when this situation happens:

http://evcc.local:7070/api/state

I'm unsure why this mismatch happens.

[andig]

@naltatis why is this labeled as enhancement? Afaikt we're still trying to find an actual issue here?

[naltatis]

Gute Frage. Möglicherweise das falsche issue erwischt.
