A system configured to associate information with an asset or a physical space, comprising: a plurality of building control fixtures (202, 510, 610, 710, 1510) located within a structure (500, 600, 1000), each of the plurality of building control fixtures comprising: a sensor unit (230, 780) configured to generate a sense signal based on a sensed motion, wherein the sensor unit comprises: communication circuitry (250, 740) configured to maintain a link with a network; a controller configured to manage communication with the network, wherein the communication comprises communicating information of the sense signal; wherein at least one of a controller (520, 620, 720, 1575), which is external to the plurality of building control fixtures and included in the system, or at least one controller of the plurality of building control fixtures (202, 510, 610, 710) is configured to: track a location of a first mobile device (530, 630, 1530) within the structure (500, 600, 1000) based on the locations of the plurality of building control fixtures, on the received signal strength of beacons communicated between the sensor units and the first mobile device, and on the sensed motion, wherein the tracked locations include location estimates, wherein new location estimates based on the beacons that correspond with a location in which a building control fixture has not sensed motion are given a lower probability estimate compared to a location in which a building control fixture has sensed motion; identify the first mobile device being within a threshold distance of a physical place based on the tracked locations of the first mobile device and a location of the physical space; and allow the first mobile device or a user of the first mobile device to receive information associated with the physical place, or to provide information to be associated with the physical place upon identifying that the first mobile device is within the threshold distance of the physical place. a plurality of building control fixtures (202, 510, 610, 710, 1510) located within a structure (500, 600, 1000), each of the plurality of building control fixtures comprising: a sensor unit (230, 780) configured to generate a sense signal based on a sensed motion, wherein the sensor unit comprises: communication circuitry (250, 740) configured to maintain a link with a network;
