Claim 0:
1. A computer-implemented method for saving energies at homes and offices with an Internet of Things (IoT) system, comprising:
receiving, by a computing device from each of a plurality of power receptacles, power usage information of an electrical device attached to the power receptacle;
generating, by the computing device for each of the plurality of power receptacles, a plurality of power usage metrics of the power receptacle based on the power usage information, wherein the plurality of power usage metrics comprise a power-switch frequency of the electrical device attached to the power receptacle and power consumption of the electrical device;
feeding, by the computing device, the plurality of power usage metrics into a machine learning model to obtain a priority of the electrical device attached to the power receptacle, wherein the priority is one of a plurality of pre-configured priorities;
obtaining, by the computing device, a power management signal; and
generating and transmitting, by the computing device, a plurality of control signals to the plurality of power receptacles based on the power management signal and respective priorities of the plurality of electrical devices attached to the plurality of power receptacles, wherein the generating and transmitting comprises:
if the power management signal being entering a power-saving mode and the priority of the electrical device is high, sending a query signal to the power receptacle corresponding to the electrical device to query if the electrical device is safe to shut down; and
if the power management signal being entering a power-saving mode and the priority of the electrical device is low, sending a shutdown signal to the power receptacle corresponding to the electrical device to shut down the electrical device.
