9. The device of claim 8 wherein the plug insertion switch and dial selector switch are coupled to a housing enclosing the electrical outlet and the electrical outlet is operative to supply the electrical load with electric power.
10. The device of claim 1 wherein the indicia are derived from frequency of use of the electrical load and time duration of uses of the electrical load.
11. The device of claim 1 further including:
an electrical outlet having a single circuit for receiving electric power;
the electrical outlet operative to supply the electrical load with electric power;
an automated switch operative to interrupt power supplied to the electrical outlet;

the voltage transducer interposed between the switch and the electrical outlet.
12. The device of claim 1 wherein the indicia include at least one indicium derived from one of a group consisting of load current versus time data collected as operating current initially flows to the electrical load and load voltage versus time data collected as the operating current initially ceases to flow to the electrical load.
13. The device of claim 12 wherein the collected load current versus time data represents a current-time waveform and the collected load voltage versus time data represents a voltage-time waveform.
14. The device of claim 1 wherein the indicia include at least one indicium derived from one of a group consisting of a Fourier transform of load current versus time data collected as operating current initially flows to the electrical load and a Fourier transform of load voltage versus time data collected as the operating current initially ceases to flow to the electrical load.
15. A method for assessing a nature of an electrical load comprising the steps of;
providing a transducer block interposed between a power supply and an electrical load;
providing a signal electronics section operative to receive data from the transducer block;
providing a dial selector switch for selecting among three or more environmental variables;
in one or more processors, determining indicia based on the data received from the signal electronics section and a state of the dial selector switch;
in a processor of the one or more processors, comparing the indicia with stored indicia; and,
in a processor of the one or more processors, assessing the nature of the electrical load based on the compared indicia.
16. The method of claim 15 wherein the nature of the electrical load includes a model number of electrical load.
17. The method of claim 15 wherein a first processor that is adjacent to the electrical load in a residence analyzes the received data and a second processor that is located in a datacenter identifies a nature of the electrical load.
18. The method of claim 15 wherein the indicia include indicia that are derived from state changes of a plug insertion switch associated with an electric outlet adjacent to the electrical load.
19. The method of claim 15 wherein the indicia include at least one indicium derived from one of a group consisting of load current versus time data collected as operating current initially flows to the electrical load and load voltage versus time data collected as the operating current initially ceases to flow to the electrical load.
