1. A system for monitoring hot water supply in a load control network, comprising:
a multi-meter provided external to a water heater and having an electrical supply input and an electrical supply output to an electrical power supply circuit of said water heater, said multi-meter comprising:
a voltage monitor configured to determine a voltage of said electrical power supply circuit;
a current monitor configured to determine a current of said electrical power supply circuit; and
a metering chip configured to determine which of an upper heating element of said water heater and a lower heating element of said water heater is presently energized based on one or more of said voltage of said electrical power supply circuit, said current of said electrical power supply circuit, and a power factor of said electrical power supply circuit;
wherein said determination of which of said upper heating element and said lower heating element of said water heater is presently energized comprises determining a resistance of at least one of said upper heating element and said lower heating element based upon said one or more of said voltage of said electrical power supply circuit and said current of said electrical power supply circuit; and
wherein said metering chip is further configured to record a first measured resistance as a resistance of said lower heating element based on a first one of said lower heating element and said upper heating element to be energized by said electrical power supply circuit.
