I placed a current sensor on the main power line going into my household and I m trying to use that data to determine if an appliance is pluged in such as a fridge or heater. It should be easy since a resistor would draw current diffrently then a electric motor. however the fact that all the currents are added up I cannot do it. The only thing I can detect is if a fridge or a heater is on from the huge inrush current they draw at startup. And unfortunatly they are all at the same frequencies.
Any idea on how this could work would be helpful
