Water leak detection

Abstract

Systems and methods for detecting water leaks using a security and/or automation system includes receiving total water usage data for a home, receiving water usage data for known sources in the home, receiving occupancy data for at least one occupant in the home, and determining a water leak based at least in part on the total water usage data, water usage data for known sources, and occupancy data.

What is claimed is: 
     
         1 . A method for detecting water leaks using a security and/or automation system, comprising:
 receiving total water usage data for a home;   receiving water usage data for known sources in the home;   receiving occupancy data for at least one occupant in the home; and   determining a water leak based at least in part on the total water usage data, water usage data for known sources, and occupancy data.   
     
     
         2 . The method of  claim 1 , wherein receiving total water usage data includes at least one of:
 receiving water usage data from a water utility company;   receiving water usage data from a flow meter located in a water main for the home; and   receiving water pressure data from a pressure sampling device placed in a free spigot or water outlet of the home.   
     
     
         3 . The method of  claim 1 , wherein receiving water usage data for known sources includes receiving sensor data associated with use of at least one of a dishwasher, a clothes washing machine, a humidifier, an ice machine, and a sprinkler system. 
     
     
         4 . The method of  claim 1 , wherein receiving water usage data for known sources includes determining an amount of water used by at least one of a dishwasher, a clothes washing machine, a humidifier, an ice machine, and a sprinkler system. 
     
     
         5 . The method of  claim 1 , wherein receiving occupancy data includes receiving at least one of detected operation of a setting of the security and/or automation system, detected operation of a door of the home, detected operation of an appliance in the home, detected operation of a lock of the home, detected use of a furniture item of the home, or detected motion in the home. 
     
     
         6 . The method of  claim 1 , wherein determining the water leak include disaggregating water usage based at least in part on the known sources of water usage and occupancy. 
     
     
         7 . The method of  claim 6 , wherein disaggregating includes determining usage of water sources that should not occur when no occupants are present in the home. 
     
     
         8 . The method of  claim 1 , wherein receiving occupancy data includes receiving occupancy data when the at least one occupant is in bed. 
     
     
         9 . An apparatus for security and/or automation systems, comprising:
 a processor;   memory in electronic communication with the processor; and   instructions stored in the memory, the instructions being executable by the processor to:   determine total water usage for a home from a first water usage input;   determine water usage for known sources in the home from at least one second water usage input;   determine occupancy of at least one occupant in the home using occupancy data; and   determine a water leak based at least in part on the total water usage, water usage data for known sources, and occupancy.   
     
     
         10 . The apparatus of  claim 9 , wherein determining total water usage data includes at least one of:
 receiving water usage data from a water utility company;   receiving water usage data from a flow meter located in a water main for the home; and   receiving water pressure data from a pressure sampling device placed in a free spigot or water outlet of the home.   
     
     
         11 . The apparatus of  claim 9 , wherein determining water usage data for known sources includes receiving sensor data associated with use of at least one of a dishwasher, a clothes washing machine, a humidifier, an ice machine, and a sprinkler system. 
     
     
         12 . The apparatus of  claim 9 , wherein determining water usage data for known sources includes determining an amount of water used by at least one of a dishwasher, a clothes washing machine, a humidifier, an ice machine, and a sprinkler system. 
     
     
         13 . The apparatus of  claim 9 , wherein determining occupancy includes receiving at least one of detected operation of a setting of the security and/or automation system, detected operation of a door of the home, detected operation of an appliance in the home, detected operation of a lock of the home, detected use of a furniture item of the home, and detected motion in the home. 
     
     
         14 . The apparatus of  claim 9 , wherein determining a water leak include disaggregating water usage based at least in part on the known sources of water usage and occupancy. 
     
     
         15 . The apparatus of  claim 14 , wherein disaggregating includes determining usage of water sources that should not occur when no occupants are present in the home. 
     
     
         16 . The apparatus of  claim 9 , wherein receiving occupancy data includes receiving occupancy data when the at least one occupant is in bed. 
     
     
         17 . A non-transitory computer-readable medium storing computer-executable code for security and/or automation systems, the code executable by a processor to:
 determine total water usage for a home;   determine occupancy for the home; and   determine a water leak based at least in part on the total water usage and occupancy.   
     
     
         18 . The non-transitory computer-readable medium according to  claim 17 , the code executable by the processor to:
 determine water usage data for known water usage sources in the home;   wherein determining the water leak is based at least in part on the determined water usage data for known water usage sources.   
     
     
         19 . The non-transitory computer-readable medium according to  claim 18 , wherein determining water usage data for known sources in the home includes at least one of:
 receiving sensor data associated with use of at least one known water usage source in the home; and   determining an amount of water used by the at least one known water usage source in the home.   
     
     
         20 . The non-transitory computer-readable medium according to  claim 17 , wherein determining total water usage includes at least one of:
 receiving water usage data from a water utility company;   receiving water usage data from a flow meter located in a water main for the home; and   receiving water pressure data from a pressure sampling device placed in a free spigot or water outlet of the home.
