Bonus hint on your config: You should rather go with a 20s timeout for the Easee. The entire client <-> cloud API <-> charger roundtrip regularly takes more than 10s.
I checked the provided log, evcc is sending the commands as expected, so nothing in the logic wrong. However, looking at the explicit values, I am wondering if your system has been properly setup by your electrician. Your circuit settings indicate 1000A per phase as maximum current. Please correct me, but to me that looks like an utterly unrealistic value.
My working theory is, that as we use the max Current to switch phases, but the value is unrealistic, the command gets ignored by the charger.
Can you please double check what the max amps show for the circuit (either on the easee web portal or via the app)?

@premultiply just quick sanity check - are there installations that big (i.e. 1000A) or can we already consider this a misconfiguration on site/circuit level?
As far as I know germany the limit for grid connections to the lowest grid layer ("Niederspannungsnetz") is ~250 kVA using 3 ~400A fuses at the transformer.
@GrimmiMeloni Can you please double check what the max amps show for the circuit (either on the easee web portal or via the app)?:
Yes, it really shows 1000A:
What would be the proper setting value?
By the way, switching from 1p->3p works, if I switch EVCC mode to OFF and back to PV. I have attached this log as well. But I see a log entry for mqtt syntax error: [mqtt ] ERROR 2024/07/26 13:22:18 set evcc/loadpoints/1/phases/set: strconv.Atoi: parsing "NaN": invalid syntax evcc-20240726-132559-trace.log
What would be the proper setting value?
I am no electrician, so I don‘t know for sure. I think this depends on the fuses on the circuit your wallbox is attached to. Whoever installed the charger for you should know.
Describe the bug
I have just a single easee home wallbox. Whenever loadpoint lp-1 exeeds 3p threshold, it starts scale3p switch, but easee does not physically switch from 1p->3p. It remains 1p. Later a "charger logic error: phases mismatch (got 1, expected 3)" is logged.
