Load balancing current to EV-charger

Configuration
20

I have changed script after those old ones.

I have now P1 (HAN) port in electricity meter, and it outputs current readings in 10 second intervalls. That old one rises/lowers current 1A/every measurement, so it Takes 100 secondsfrom 16A to 6A.
Now i have modified it so, that it sets current in one step.

This is to be modified for each own needs

sensor.p1_meter_current_phase_1 = L1 Current in amps (A)
sensor.p1_meter_current_phase_1 = L2 Current in amps (A)
sensor.p1_meter_current_phase_1 = L3 Current in amps (A)
min_charge_current = minimum current charger allows (A)
max_charge_current = maximum current charger allows (A)
max_total_current = breaker size. This is max target total current for L1-L3 (A)
number.go_echarger_xxxxxx_amp = charger current setting entity (A)
