Abstract: A semi-autonomous or autonomous system providing a means of controlling lighting, fans, and other electric loads. The system may include a user interface that presents similarly to a traditional rocker or other form of light switch. The system may sense one or more conditions using one r more types of sensors and react based on the sensed conditions. Examples of reactions may include dynamically compensating for changes in ambient temperature or light level, dimming before bedtime or brightening before waking to influence circadian rhythms, and turning on and off based on presence or absence in an environment.
