Interpreting presence signals using historical data

A monitoring system that is configured to monitor a property, the monitoring system comprising:

• one or more sensors that are located at the property;
• and a monitoring server configured to perform operations comprising:
• collecting data sensed by the monitoring system that monitors a property of a user;
• aggregating, over a period of time, the collected data sensed by the monitoring system that monitors the property of the user;
• detecting, within the aggregated data sensed over the period of time by the monitoring system that monitors the property of the user, patterns of recurring events at the property;
• receiving at least one presence signal related to presence of the user at the property monitored by the monitoring system;
• interpreting the at least one presence signal in accordance with the detected patterns of recurring events at the property;
• and
• taking action related to the monitoring system based on the interpretation of the at least one presence signal in accordance with the detected patterns of recurring events at the property;
• wherein detecting, within the aggregated data sensed over the period of time by the monitoring system that monitors the property of the user, patterns of recurring events at the property comprises assigning a confidence score for a pattern of recurring events that reflects a level of confidence that the detected pattern is actually a pattern of recurring events that will be observed in the future, the assigned confidence score being based on a percentage of time the pattern has occurred previously, an amount of data used in detecting the pattern, and a statistical technique that assesses whether the pattern is a statistically significant pattern of recurring events;
• wherein receiving at least one presence signal related to presence of the user at the property monitored by the monitoring system comprises receiving at least one sensor signal from a door sensor, a motion detection sensor, or a window sensor.
