Management apparatus and management method for electrical appliances

This invention describes a system that automatically figures out which electrical appliance is plugged into which wall outlet. It works by measuring the power drawn from an outlet and the power consumed by an appliance over the same time period. If the power patterns match closely enough, the system wirelessly associates that specific appliance with that specific outlet. The claims narrow this to a system with a wireless module, a processor, and software to perform the comparison.

Why it matters: Filed before widespread, low-cost smart home hardware and robust wireless IoT protocols were common. The necessary power measurement and communication components are now commodity items, making implementation significantly more feasible and affordable.
