1. A method for automation control for water leaks, the method comprising:

  • receiving, by a control device, a first set of one or more sensor readings from a first set of one or more sensors disposed about one or more water supply lines at a home, the first set of one or more sensors to detect a type of one or more metrics indicative of water flow;

    recording, by the control device, the first set of one or more sensor readings over a time period;

    receiving, by the control device, a second set of one or more sensor readings from a second set of one or more sensors disposed at the home, the second set of one or more sensors to detect presence and/or locations of one or more occupants at the home;

    identifying, by the control device, a correlation between the first set of one or more sensor readings indicative of the water flow over the time period and the second set of one or more sensor readings indicative of the presence and/or the locations of the one or more occupants at the home;

    generating, by the control device, an activity profile based at least in part on the correlation;

    generating, by the control device, a water use profile based at least in part on the activity profile, wherein the water use profile indicates water flow trends corresponding to circumstances identified with the activity profile;

    identifying, by the control device, a set of one or more thresholds based at least in part on the water use profile;

    retaining, by the control device, the set of one or more thresholds in association with the activity profile;

    monitoring, by the control device, water use at the home at least in part with the first set of one or more sensors and activity at the home at least in part with the second set of one or more sensors;

    determining, by the control device, a water leak condition based at least in part on the monitoring, wherein the determining the water leak condition comprises;

    matching monitored activity to the activity profile;

    comparing a third set of one or more sensor readings indicative of monitored water use to at least one threshold of the set of one or more thresholds; and

    determining that the at least one threshold is satisfied;

    determining, by the control device, an adjustment to address the water leak condition; and

    causing, by the control device, a water supply controller to make the adjustment, wherein the adjustment comprises shutting off a water supply.
