1. An energy meter for managing the distribution of electrical energy, said meter comprising:

  • at least one sensor coupled with an electric circuit and operative to sense at least one electrical parameter in said electric circuit and generate at least one analog signal indicative thereof;

    a meter housing;

    at least one analog to digital converter located in said meter housing and coupled with said at least one sensor and operative to receive said at least one analog signal and convert said at least one analog signal to at least one first digital signal;

    a communications port located in said meter housing and operative to facilitate communications of at least one second digital signal between said energy meter and a slave device located outside of said meter housing and coupled with said energy meter using a first protocol;

    a processor located in said meter housing and coupled with said at least one analog to digital converter and further coupled with said communications port, said processor operative to perform a power management function on said at least one second digital signal and generate an output result; and

    a server module located in said meter housing and coupled with said processor and operative to facilitate communication of said output result to a client application over a digital network located outside of said meter housing using a second protocol to manage the distribution of electrical energy.
