Describe the issue you are experiencing

Home energy flow is showing high battery flows from battery to grid, and grid to home.

The actual flows are grid to battery and battery to home, the raw data higher up is correct, but the flows are all over the place.

Describe the behavior you expected

I would expect to see high grid to battery flows and high battery to home, we’re entirely off grid during peak times and only draw from the grid off peak, including charging battery.

Steps to reproduce the issue

There’s not steps it’s just the new energy flow on the energy tab

Can you please attach an energy CSV export, it should have all the numbers in it. Then point out which cells specifically you think are incorrect.

We can't reliably predict this with the current config data we have. We assume that the batteries are charged from solar as that is the most common scenario. Maybe we can prioritize grid return before battery charging for solar excess but this will be incorrect for people that fill their battery and then start exporting to the grid.

Hello I have same issue on my side. My battery can be charged via solar panel but also during the night from the grid with off-peak hours. During the night, we can see a negative number like injection, but this correspond well to consumption from the grid.
