Device based on activity within property

A system comprising one or more computers and one or more storage devices on which are stored instructions that are operable, when executed by the one or more computers, to cause the one or more computers to perform operations comprising:

• maintaining, in memory and for a property, a historical activity model that indicates historical patterns of use or movement at the property and was generated using first sensor data from one or more sensors at the property;
• and
• while maintaining the activity model:
• receiving, from a sensor at the property, second sensor data that has a different type than the first sensor data;
• determining, using the second sensor data and the historical activity model for the property, whether a criterion for a device is true;
• and
• controlling, using a result of the determination, a setting that affects a functioning of the device at the property.

One or more non-transitory computer storage media encoded with instructions that, when executed by one or more computers, cause the one or more computers to perform operations comprising:

• maintaining, in memory and for a property, an activity model that indicates patterns of use or movement at the property and was generated using first sensor data from one or more sensors at the property;
• and
• while maintaining the activity model:
• receiving, from a sensor at the property, second sensor data separate from the first sensor data used to generate the activity model;
• determining, using the second sensor data and the activity model, whether a criterion for a device is true;
• and
• controlling, using a result of the determination, a setting that affects a functioning of the device at the property.
