1. A method for security and/or automation systems, comprising: receiving social media data via a signal; analyzing the social media data based at least in part on a first parameter to determine first occupancy information at a structure; identifying a first probability associated with the first occupancy information based at least in part on analyzing the social media; modifying the first probability based at least in part on analysis of the first occupancy information determined from the social media in relation to analysis of second occupancy information determined from sensor data received from a sensor located at the structure, the sensor including at least one of a motion sensor, camera sensor, thermostat sensor, proximity sensor, or audio sensor, or any combination thereof; and assessing a structure occupancy based at least in part on the modified probability.
