Abstract: Various arrangements for monitoring and controlling operation of a HVAC system are provided. Battery-operated temperature monitoring devices may be situated within the structure and connected with a network. A user command may be received that includes a selection of at least one of the battery-operated temperature monitoring devices. An offset may be calculated based on an evaluation of a first temperature reading of the selected battery-operated temperature monitoring device relative to a second temperature reading of the thermostat. The offset may be overridden when an override condition is present.

Abstract: A method for monitoring and controlling operation of a HVAC system within a structure comprises providing a thermostat configured to regulate the HVAC system. The method includes situating a plurality of battery-operated temperature monitoring devices within the structure and coupling the thermostat and each of the plurality of battery-operated temperature monitoring devices to a network. The method comprises receiving over the network a user command that includes a selection of at least one of the battery-operated temperature monitoring devices. The method includes computing at the thermostat an offset based on an evaluation of a first temperature reading of the at least one selected battery-operated temperature monitoring device relative to a second temperature reading of the thermostat. The method comprises applying the offset to the thermostat to cause the thermostat to regulate the HVAC system in view of the first temperature reading, and overriding the offset when an override condition is met.

Abstract: Techniques for determining and using a thermodynamic model that characterizes a thermodynamic response of an enclosure conditioned by an HVAC system are disclosed. To determine a thermodynamic model, temperature information when the HVAC system operates in a first state may first be received. A response interval may then be determined where the response interval indicates an estimated time between when the HVAC system begins operating in the first state and when the temperature within the enclosure begins to change in a direction associated with the first state. Weighting factors corresponding to basis functions may then be determined, where the weighted basis functions characterize the temperature trajectory of the enclosure in response to the HVAC system operating in the first state.
