1. A method for monitoring a home for a leak within a home network that includes a water meter for measuring water consumption within the home network and a central controller communicatively linked to the water meter, the central controller including at least one memory for storing executable instructions, the method comprising:

  • tracking a total water flow to a water consuming device for a period of time;

    identifying a maximum amount of the total water flow to the water consuming device that occurs during a subinterval length of time in the period of time;

    assigning the maximum amount to a threshold value;

    receiving communication data at the central controller, the communication data reflecting a total water flow amount from a water pipeline that is operatively coupled to the water meter;

    tracking the total water flow amount of the water pipeline over the subinterval length of time from the water meter;

    analyzing the total water flow amount by comparing the total water flow amount to the threshold value; and

    generating an output to an end user that alerts the end user of a leak when the total water flow amount exceeds the threshold value for the subinterval length of time.
