Dynamic water leak detection

A system comprising:

• one or more processors;
• and
• one or more storage devices, the one or more storage devices storing instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
• receiving, from one or more sensors that are located throughout a property that is monitored by a monitoring system, sensor data;
• determining that the sensor data is not available or is inconclusive;
• in response to determining that the sensor data is not available or is inconclusive, selecting, from a plurality of different water usage modes each of which have corresponding different one or more water usage criteria, a base water usage mode of the property;
• determining, using the base water usage mode, the one or more water usage criteria for the base water usage mode;
• receiving current water usage data representing water usage at the property;
• determining, based on the current water usage data, that water usage at the property satisfies the one or more water usage criteria;
• and
• in response to determining that the water usage at the property satisfies the one or more water usage criteria, determining that a water leak exists at the property.

A non-transitory computer readable storage medium storing instructions executable by a data processing apparatus and upon such execution cause the data processing apparatus to perform operations comprising:

• receiving, from one or more sensors that are located throughout a property that is monitored by a monitoring system, sensor data;
• determining that the sensor data is not available or is inconclusive;
• in response to determining that the sensor data is not available or is inconclusive, selecting, from a plurality of different water usage modes each of which have corresponding different one or more water usage criteria, a base water usage mode of the property;
• determining, using the base water usage mode, the one or more water usage criteria for the base water usage mode;
• receiving current water usage data representing water usage at the property;
• determining, based on the current water usage data, that water usage at the property satisfies the one or more water usage criteria;
• and
• in response to determining that the water usage at the property satisfies the one or more water usage criteria, determining that a water leak exists at the property.
