Describe the problem you are trying to solve

We have multiple Chargers connected to the same powersource. (4 times, later 6 EVlink Wallbox G4 Smart 7,4/22kW-T2 RFID) Charging by all stations exceeds the maximum allowed current (32A). We are using SteVe 3.5.0

Describe the solution you'd like

SteVE schedules charging for a group of charging stations, so that the given total maximum current is not exceeded.
