How many actions can the 3EM handle?

Hi! Could you please let me know how many measured power level thresholds can I set in 3EM? I'd like to follow a solar PV system's production with an HTTP controllable EV charger's amperage as close as possible. The charger can be set from 6A to 16A in 1 amp increments, so I'd need 11 different power level thresholds in 3EM, each with its unique HTTP address to call.

So I can only set a single condition (wattage number) under the "SUM OF ALL CHANNELS OVER POWER" part?
