A computer implemented method, comprising: executing, by at least one processor, a collection routine at regular intervals to gather raw data from a plurality of sensors, wherein executing the collection routine comprises varying a respective signal strength and a respective time period of two or more of a plurality of transmitters, wherein the plurality of sensors and the plurality of transmitters are included in a plurality of devices; receiving, by the at least one processor, results of the collection routine in a form of the raw data from the sensors; storing, by the at least one processor, the received results in a central data repository; setting, by the at least one processor, a device remote in a low-power mode, wherein the device remote is configured to control a television; analyzing, by the at least one processor, the stored sensor data to determine when the television is turned on or off, and when the television is determined to be turned on, using, by the at least one processor, a WiFi radio of the television to initially scan for a potential presence of one or more humans within a predetermined geographical range based on a detection of receiving multiple signals from a first transmitter of the plurality of transmitters substantially simultaneously through a second transmitter and a third transmitter, wherein the first transmitter is located in a first device, the second transmitter is located in a second device, the third transmitter is located in a third device, the first device, the second device, and the third device are placed at different three-dimensional locations around the television and in a plane at a same height, wherein the first device includes a speaker connected to the television and located at a front of a viewing space of the television; and when the one or more humans are determined by the at least one processor to be potentially present, executing, by the at least one processor, a first action; and when the television is determined to be turned off, executing, by the at least one processor, a second action. executing, by at least one processor, a collection routine at regular intervals to gather raw data from a plurality of sensors, wherein executing the collection routine comprises varying a respective signal strength and a respective time period of two or more of a plurality of transmitters, wherein the plurality of sensors and the plurality of transmitters are included in a plurality of devices;
