Two problems

[freto036]

Hey everyone,
about three weeks ago our solar system went operational and after initially not being smart enough to figure out the go-e integration, I was eventually able to set everything up that way, that only PV surplus would be used to charge the car. That worked pretty well. For the last week or so, I have run into some issues though and would absolutely love if somebody could point me in the correct direction.
As far as I am aware no settings were changed to cause this change in behavior.

1. The charger will stop charging every so often and not restart despite plenty of surplus being available. With plenty I mean upwards of 8kW. When trying to check the API values it receives from HA I get an error message in the browser saying the connection was reset.
2. I have noticed, that once the charging starts, there no longer seems to be adjustments depending on how much surplus is available, draining the battery and after that starting to draw electricity from the grid, to keep charging at the initial rate.

I think that those two problems might be connected, but I don't have enough of a clue to KNOW whether they are.

I am running the following versions:
HA integration 2025.7.0
go-e firmware 59.4

The PV surplus section of the charger is setup as follows:
starting power level 2.00kW
power preference: power to grid
grid target -200W
phase switching automatic
3-phase power level 4.20kW

I would very much appreciate some pointers.

The only thing you might like to check is the WLAN signal quality? When you have issues reaching the Wallbox API via your Browser... then the HA integration/automation might have the same problem?

I have no idea where those values are supposed to be, but signal strength according to the wallbox is between -74dB and -54dB, averaging around -60dB for the vast majority of the time. But yes, I would assume that HA won't be able to read anything if I can't reach it either.
