Sun Grow AC22E-01 TCP IP Communication Problems

[davidbuecheler]

Hi
I use evcc inside home assistant. Wallbox has the firmware LE-01.1e1.001.901.17
config see below. I get a connection, the car is found correctly as well as the loading state of the car. Also the total energy is delivered from the wallbox to evcc.

But like one second after start of charging, I get the follwoing error "[lp-1 ] ERROR switch phases: modbus: response value '35917' does not match request '1'" Then the charging stops.

I do not understand why it even tries to change phases. In EVCC 3 phases are set. In the car settings also.

This is my first post, so pleas be gentile...
