Abstract
A portable energy monitoring point includes at least one power plug receptacle, each power plug receptacle operably coupled to a separate integral power sensor circuit. Each integral power sensor circuit is configured to determine an electrical current drawn by an electrical load connected to the corresponding at least one power plug receptacle. An integral digital communications circuit is configured to wirelessly transmit to a remote device a power consumption for each of the at least one power plug receptacles. The power consumption is derived from the electrical current drawn by the electrical load connected to the corresponding at least one power plug receptacle.
