go-e Charger -> no PV share calculated

[rosch99]

Describe the bug
PV-Share is not calculated when using go-e charger wallbox.

Expected behavior
newer firmware versions support the following additional API keys so it should be possible to calculate PV share while charging.
pgrid --> PowerGrid (in Watt)
ppv --> PowerPV (in Watt)
pakku --> PowerAkku (in Watt)

Screenshots
If applicable, add screenshots to help explain your problem.

** Teslalogger Type **
Docker on a Raspberry Pi4
Did you update the Image with apt-get update & upgrade?

** Do you use Tasker or iBeacon **
no

Hey, grid power (kW) doesn't help. We need energy (kWh).

[rosch99]

Does that mean the wallbox needs to calculate the PV share?
I dont think go-e charger can do that, imho "pgrid", "ppv" and "pakku" are (only) used to calculate power for surplus charging.

calculate power for surplus charging

That's the problem: power, we need energy ;)
If a wallbox has energy values for the grid (like cFos, openWB...), we can use it. Power only doen't help at all in our case.

Ok, i got it.
What i dont get is, since energy is power for a given time (kWh) which timeframe should be used to calc the PV share?
Is it energy_Grid and energy_PV for THIS charging session, could be complicated to get?
How is this calculated (and reported) by cFos, openWB?

[Adminius]

cFos (and openWB) has direct connection to the Meter and get precalculated kWh

You can't take power x time, because time should be each second, because you charging with PV and power differs every second...
