Any body knows how is the real process of measurement and how accurate could be? Let say, you have a dimerizable Lamp attached to this TP-Link Smart Plug, as soon as you change the level of the light the value of consumption doesn´t change in real-time, it sounds the algorithm takes the consumption value from the circuit that "measures" the consumption, but in discrete way with some time interval (1 min, 5 min?), the algorithm could make an average of the samples to calculate the consumption and the app pull that information, it could mean an error variance % of the real consumption of the appliance. Can some TP-Link representative answer to the real process of measurement and accuracy?
