After I updated 56.8, I observed that the PV optimized charging not longer worked properly.
In my setup (huawei PV, homeassistant with API2, go-e), the charger caps the current on each phase to max 5A. When there is enough power from PV (4.2kW), the phase switch to 3 phases works, but still only 5A on each phase. Downgrade to 56.1 did make it work again, but unfortunately the sun was then soon gone to do further tests.
Here some more details to illustrate the issue:
You can nicely see how PV did not go into car:
Go-e did see the surplus (so API transmits correct values), but charger did nothing:
L1 was limited to 5A (I did downgrade of the FW around 14:30 )
Settings were correct:
There have been no reported errors.
It does not seem to be linked to the API2 integration in HA (this is a copy of what I originally posted there marq24/ha-goecharger-api2#11 (comment)) but more likely to some firmware changes that mess with the PV surplus charging algorithm.
Would be great to have access to the FW changelog. The app does not show a changelog for 56.2 and 56.8.
The weirdest thing is that the API can only limit current to minimum of 6A number.goe_259493_ama (and mine was set to 16A), so not sure how a cap of 5A is even possible.
