This disclosure concerns estimating the number of people within building-based device networks. Increasingly, local area network (LAN) devices are capable of sensing people (e.g. smart appliances). Features of building layout, and physical arrangement of devices provide that only a subset of sensor data patterns can be accounted for by a single user (e.g. simultaneous activation of a smart TV and a motion sensor). Over time, a central controller (e.g. LAN gateway) can gather these building-specific sensor patterns and learn single occupant characteristics for a network (e.g. features or boundaries of single occupant capability). In one embodiment, the central controller generates a single occupancy criterion (e.g. a building-specific test), comprising single occupant characteristics, operable to test a subset of sensor data for single occupancy. The central controller divides devices into a minimum number of groups, such that each group satisfies the single occupancy criterion and estimates the number of occupants accordingly. |

1. A computer implemented method comprising:
a. obtaining a set of sensor data, indicative of occupancy within at least some of a region, and comprising sensor data from each of a plurality of devices in the region, b. obtaining a single occupancy criterion, comprising a test based on a plurality of single occupant characteristics, and satisfied by a candidate subset of the set of sensor data when the candidate subset passes the test, c. processing one or more subsets of the set of sensor data according to the single occupancy criterion, to identify one or more groups of devices each indicative of a single occupant,
wherein the single occupancy criterion functions in the processing to determine whether each of the one or more subsets of the set of sensor data can be accounted for by a single occupant,wherein the processing identifies a set of groups of devices from the plurality devices such that for each of the set of groups of devices the corresponding subset of the set of sensor data satisfies the single occupancy criterion, and such that each of the plurality of devices is included in at least one group of devices in the set of groups of devices, and d. estimating the number of people in the region according to the number of groups of devices in the set of groups of devices. |
