If charging speed changes during charging, a wrong value is shown in your app.
I have a relay, that cuts 2 phases, if a consumer in my house needs high consumption.
Your app shows a speed of 11.14kW, the Tesla app correctly shows 3kW (what should be 3.7kW).
Both, your app and the Tesla app, show 3 phases, what is wrong.
But I think that could only be corrected, if you compare the speed with the voltage and amps.
1x16x232 = 3,7kW and 3x16x232=11,14kW
I don't know if you get both values from the car.
