Hello,
since some weeks i am using a dynamic energy tariff (tibber) and charge my home battery (huawei luna) from grid if prices are cheap.
The sensor is provided by the tibber ha integration and shows my consumption directly extracted from my smart meter.
Last night i charged my battery starting at 3am with ~ 4kWh.
The sensor shows this (Increase from 7993 kWh to 7997 kWh)

In the energy dashboard you can see that the battery was also charged ~3.6kWh, but consumption from grid is only shown with ~0,56kWh.
Also the sources overview on the energy overview is correct, but in the energy consumpion overview most of the consumption is missing...

Any ideas where to start investigating?

I think from several bug reports I recall reading that energy calculations are not really written correctly if you charge battery from grid

#

it kind of assumes that you charge it from solar

@azure sedge From my perspective the visualization is correct so maybe you can elaborate, why you think it is shown incorrectly?

It's not the most intuitive to have "Total grid import" be the distance between the top of the positive "consumption" and the bottom of the negative "battery charged"
It would make more sense to treat grid -> battery as consumption and have it show as a positive

What would be the result, when you charge the battery from grid and use up the charge in the same hour?
For example: charging 1 kWh and using the 1 kWh charge between 3:00 and 4:00 o'clock would in the graph show a positive consumption value of 2 kWh, but you only imported 1 kWh from the grid.

Show it as 1kWh consumed - same as would happen currently

#

If that happened currently it would display 0 going into the battery anyway

i think i understand what you are refering to. The graph shows the energy usage, not the energy flow as i expect.
So if i charge my homebattery from the grid it is not used "from the grid" but it is stored (negative usage) in my battery.
Makes kind of sence, but you not what i expected from the chart on the first place...

Yeah, same here! This isn’t what I’d expect from the chart either. It’s pretty weird that charging the battery from the grid doesn’t just show up as grid consumption but instead gets logged as “negative usage” in the battery. I get that it’s meant to show energy flow, but it’s definitely not how I’d interpret “energy consumption” at first glance.

Does anyone know if this has already been reported on GitHub? (I’m not totally sure if that’s the right route to take since I’m not super familiar with how these things are handled.) Still, it might be worth checking or opening an issue—it feels like something that could confuse a lot of people.

When you can describe or create a mockup how it could be displayed better than I think it is fine to open a discussion at https://github.com/home-assistant/frontend/discussions.

With this current way of handling battery charge, don't we also skew the cost data? Since there is zero cost associated with energy utilized from battery?
