1. A computerized system comprising:

  • at least one intermediate node;

    wherein said at least one intermediate node is connected to a plurality of sensors operable to monitor usage of a resource;

    wherein said at least one intermediate node is connected to an operator node;

    wherein said at least one intermediate node comprises;

    a receiver configured to receive data from the plurality of sensors,wherein the data is indicative of usage of the resource during a timeframe,wherein the data received from the plurality of sensors comprises a list of a predetermined number of values of monitored resource consumption values,wherein the list corresponds to a point in a space having n-dimensions;

    wherein n is the predetermined number of values;

    wherein the clustering module is configured to determine a cluster of the set of clusters based on distances between points in a space, andwherein the points correspond to the data;

    a clustering module configured to determine a set of clusters based upon the data;

    wherein each cluster of the set of clusters groups one or more sensors of the plurality of sensors;

    a data reduction module configured to determine a reduced data associated with a cluster of the set of clusters;

    the reduced data comprises;

    a consumption profile indicative of usage of the resource during the timeframe; and

    identifications of sensors grouped by the cluster; and

    a transmitter configured to send the reduced data.
