Method of managing energy consumption

Abstract

A method of managing energy consumption which is applied to a wireless control system is provided, wherein the wireless control system includes a plurality of appliances and a relay device. The method includes the steps below: first, obtain an amount of energy consumption from a start time point to a predetermined time point in an energy monitoring period; next, compare the amount of energy consumption with a second threshold during the energy monitoring period, which is lower than a first threshold; finally, if the amount of energy consumption exceeds the second threshold, determine whether to start an energy conservation mode; if the energy conservation mode starts, the relay device sends an energy conservation command to at least one of the appliances to control said appliance to consume less energy. Whereby, in the energy conservation mode, the energy consumed by the appliances would be reduced without stopping the energy supply.
