Abstract: Methods and devices for controlling a heating, ventilation, and air conditioning (HVAC) system by a thermostat are provided. Input can be received from a user via a thermostat, the input being indicative of an adjustment of an HVAC-related setting. On a real-time basis, the HVAC-related setting that is being adjusted can be compared against a feedback criterion designed to indicate a circumstance under which feedback is to be presented to the user. The circumstance can be indicative of an achievement of a HVAC-related setting of a predetermined responsibility level with respect to an energy usage of the HVAC system. Upon a real-time determination that the feedback criterion is satisfied, visual feedback can be caused to be presented to the user in real-time. The real-time feedback can include a visual icon having a visual appeal corresponding to a desirability of the satisfaction of the feedback criterion.

Abstract: Hazard detector for providing a pre-alarm of a developing hazardous condition includes a detection module that detects a hazard level of smoke or carbon monoxide, a storage module that stores a pre-alarm threshold and an emergency threshold, a light source that generates light in a first color, a second color, and a third color, a speaker that generates an audible sound, a horn that generates an audible alarm that a higher volume than the speaker, and a processing module. The processing module receives the detected hazard level and compares it with the pre-alarm threshold and the emergency threshold.

Upon learning the offset value, the path light may subtract the offset value from a detected amount of light to determine whether the lighting conditions of its surroundings still meet a threshold level of darkness for the path light to illuminate.
