Hello all, my problem is quite specific but I’ll give it a try anyways.
My situation:
I have 2 EVs that I charge from my PV. When the sun is gone i would like to keep charging the EVs from my homebatterie until I reach a SOC of 30% (enougth to get me through the night)
My hardware:
I use a Victron multiplus 5000 and a go-e wallbox
My situation:
everything works great as long as i have sun. Once the sun is gone, my charging is disabled because there is not enougth excees power.
Inside the go-e app I have a parameter that defines how much excess power the PV needs to bring, to start the charge.
I can set this value to a negative number and the charging starts (unless I start too many other consumer in the house). This is exaclty what i want!! And it works exactly like I want it to work.
So the solution seemed simple: When the battery is full, set this value to -2000W and once the batterie is at 30% change the value to +1000W. This way the charging would stop and only start again when the sun is up agian.
I tested the behaviour with these values and it works great.
The problem is, that the go-e apiv2 connect doesnt allow me negative values for this parameter (even though the app does support a negative value).
I tryed to manually overwrite this limitation and found the value in the const.py file of the integration. I changed the low limit to -2000 and it also displayed me this in the attributes then. But when writing this value, it still didn’t work.
When I check the log for the entiry it seems like something went completly wrong
“go-e wallbox start leistung wurde nicht verfügbar” → translates to start leistung not available
I mean… in the end I kinda edited something I was not really supposed to edit. Does anyone have a clue what I could do to enter a negative value inside this parameter without completly changing my actual setup (everything else is working like a charm so I wanne keep it that way 
)
