Abstract: Systems and methods for detecting an occupancy of a room. The method comprises receiving, from a first door sensor associated with a door of the room, sensor readings indicative of an opening operation of the door. The method comprises determining, based on the sensor readings of the first door sensor, the occupancy status of the room to be a positive status. The method comprises receiving, from a second door sensor, sensor readings indicative of a closing and/or locking operation of the door. The method comprises determining whether the closing and/or locking operation has been performed. The method comprises upon determining that the closing and/or locking operation has been performed, validating the occupancy status of the room to be the positive status; and upon determining that the closing and/or locking operation has not been performed, triggering a supplemental detection process to detect the occupancy of the room.

Abstract: A system to detect movement of doors associated with an area of interest (AOI) is disclosed. The system comprises a pressure sensor positioned at a predefined position within the AOI, wherein the pressure sensor is operable to monitor air pressure within the AOI, and a processing device in communication with the pressure sensor. The processing device comprises one or more processors coupled to a memory storing instructions executable by the processors, and configured to monitor, using the pressure sensor, the air pressure within the AOI in real-time, detect and measure a change in the air pressure within the AOI based on the monitored air pressure, and detect opening or closing of one or more doors associated with the AOI based on the measured change in the air pressure within the AOI.

Abstract: A thermostat including a switching device, a first connector operably coupled to the switching device, a computing device in electrical communication with the switching device, and a second connector operably coupled to the computing device, wherein the computing device is configured to transmit and receive signals to the second connector over a system bus.

Abstract: A system and method to manage energy consumption in an HVAC system including a main system controller, including a near field communication interface, and at least one HVAC component in operable communication with the main system controller; wherein the main system controller is configured to compile energy consumption data from the at least one HVAC component, and transfer said energy consumption data to an auxiliary device via the near field communication interface.
