Method and System for Supervising Electrical Consumption

A method for supervising the electrical consumption of a battery-powered smart meter, comprising a measurement relating to the electrical current consumed by said meter,

• characterized in that it comprises:
• an identification of at least one functionality implemented by the meter by comparison of data relating to this measurement that are measured with signatures stored in a signature database, each signature of said database being representative of the consumption of the meter during the implementation of a functionality by said meter in a nominal operating mode of the meter;
• a monitoring over time of the sequence of functionalities thus identified and the detection of a possible drift relative to a nominal operation,
• an identification of at least one functionality implemented by the meter responsible for the drift.
