Abstract
In exemplary embodiments, methods and systems are disclosed for automating control of energy consuming devices. In an exemplary embodiment, a method generally includes analyzing wireless signal patterns inside a structure to detect motion, determining occupancy of the structure and occupant activity level based on the detected motion, and controlling operation of an energy consuming device based on the determined occupancy and occupant activity level.
Claims30
A system-performed method of providing climate control in a structure having a thermostat connected with a network, the method comprising:
- using the network, analyzing wireless signal patterns inside the structure to detect motion;
- using the network, determining occupancy of the structure and occupant activity level based on the detected motion;
- and
- using the network, controlling a set point of the thermostat based on the determined occupancy and occupant activity level.
A system for providing climate control in a structure having a thermostat connected with a network, the system comprising one or more processors connected with the thermostat through the network and configured to:
- analyze wireless signal patterns inside the structure to detect motion, the analyzing performed to determine occupancy of the structure and occupant activity level based on the detected motion;
- and
- control a set point of the thermostat based on the determined occupancy and occupant activity level.
A method for automating control of an energy consuming device, the method comprising:
- analyzing wireless signal patterns inside a structure to detect motion by using Doppler shift of Wi-Fi frequencies;
- determining occupancy of the structure and occupant activity level based on the detected motion;
- and
- automatically controlling operation of the energy consuming device based on the determined occupancy and occupant activity level without direct user engagement.
