lambda: return id(Measured_Current_1).state * 220;      this is only for CT1, if you want feedback 16CH CT's total power, need sum of all CT's power.

i'm still confused. i understand lambda: return id(Measured_Current_1).state * 220;  is only for CT1. what can i type to get total power of all 16 CT's?
