Home automation system device power optimization

A method for providing power optimization in a home automation system, comprising:

• monitoring user activity related to a room of a structure managed by the home automation system;
• maintaining a device of the home automation system that is associated with the room in a low-power state while there is no user activity related to the room, the device being an audio/video (A/V) device, a lighting device, a heating ventilation and cooling (HVAC) device, a security device or an interconnection device, the low-power state causing the device to duty cycle one or more hardware components of the device according to a first sleep interval;
• in response to detecting user activity related to the room, transitioning the device preemptively from the low-power state to a full-power state, the user activity being a user navigating to a screen for controlling the room in a control user interface (UI) displayed on a mobile device or remote control wherein the navigation to the screen occurs before use of the device, the full-power state causing the device to duty cycle the one or more hardware components of the device according to a second sleep interval, the second sleep interval having a length that is shorter than the first sleep interval;
• and
• in response to expiration of a timer since a) a last use of the device was made while the device was in the full-power state or b) the transition of the device to the full-power state was made and no actual use of the device occurred, and the user navigating away from the screen for controlling the room in the control UI to a different screen for controlling another room in the control UI, exiting the full-power state.

A home automation system that provides power optimization, comprising:

• a battery-powered device of the home automation system having one or more hardware components and being associated with a room of a structure;
• a remote control or mobile device configured to display a control user interface (UI) of the home automation system;
• and
• a host controller of the home automation system that is coupled to and configured to control the battery-powered device and a plurality of other devices of the home automation system that are associated with the room, the plurality of other devices including one or more other audio/video (A/V) devices, lighting devices, heating ventilation and cooling (HVAC) devices, security devices or interconnection devices, the host controller including host software that when executed is operable to:
• determine a user has navigated to a screen for controlling the room in the control UI,
• in response to at least the user navigating to the screen for controlling the room in the control UI, and before an attempt to use the battery-powered device by the user or another device of the home automation system in providing a second service in the room, signal the battery-powered device to transition preemptively from a low-power state in which the battery-powered device duty cycles the one or more hardware components according to a first sleep interval to a full-power state in which the battery-powered device duty cycles the one or more hardware components according to a second sleep interval, and
• in response to expiration of a timer since a) a last use of the battery-powered device was made while the device was in the full-power state or b) the transition of the device to the full-power state was made and no actual use of the device occurred, and user navigation away from the screen for controlling the room in the control UI to a different screen for controlling another room in the control UI, exit the full-power state.
