Abstract: Systems and techniques are described for monitoring screen activity of a computing device and performing designated system actions based on the monitored activity. In some implementations, activity data indicating usage of a computing device by a user within a property over a particular time period is obtained. Sensor data collected by a monitoring system that monitors the property over the particular time period is then obtained. An activity monitoring rule that specifies (i) one or more conditions associated with usage of the computing device by the user, and (ii) an action to perform in response to satisfaction of the one or more conditions is identified. A determination that the activity data and the sensor data satisfy the one or more conditions specified by the activity monitoring rule is made. The action specified by the activity monitoring rule is then performed in response to the determination.
