Patent ID: 8433530

Claim:
A system for collecting waveform data for determining at least one energy consumption profile, the system comprising: (I) a system controller; (II) a plurality of co-located multi-port monitoring devices, wherein each of said multi-port monitoring devices comprises: a) communication coupling means for communicating with the system controller; b) at least one plug that is configured to electrically couple to at least a dual-port electrical outlet upon being inserted into a socket of said at least dual port electrical outlet, wherein each of said multi-port monitoring devices comprises at least one relay to connect and disconnect to a power load and each of said multi-port monitoring devices is configured to: a) independently meter waveform data from a single port of said at least dual port electrical outlet in the case where a single electrical appliance is coupled to said single port of said multi-port monitoring device; b) independently meter waveform data from multiple ports of said at least dual port electrical outlet in the case where at least two electrical appliances are simultaneously coupled to at least two ports of said multi-port monitoring device; and c) wirelessly transmit the metered waveform data to the system controller.
