According to one embodiment, a multi-sensing hazard detector for detecting potential dangers may include a back plate and a front casing that is coupled with the back plate to define a housing. A circuit board and a plurality of components may be positioned within the housing. The circuit board may be communicatively coupled with the components. The components may include, among other components, an alarm device, an occupancy sensor, and a smoke chamber. The alarm device may be activatable upon the detection of a potential hazard to warn an occupant of a potential danger, the occupancy sensor may be configured to detect the presence and/or movement of objects external to the hazard detector, and the smoke chamber may be configured to detect the presence of smoke to cause a triggering of the alarm device. The housing may comprise a volume of less than 1024 cubic centimeters.

A user-friendly programmable thermostat is described that includes a circular body having a large central display surrounded by a ring that can be rotated an pressed inward by a user so as to receive user input in a simple elegant fashion. Different colors can be displayed to the user to indicate currently active HVAC functions, and different shades of colors can be displayed to a user to indicate an estimated amount of time and/or energy for reaching a target temperature. The thermostat is wall mountable and is made up of a head unit removeably mounted to a backplate. A locking mechanism can be provided so as to increase security against unauthorized removal of the head unit. The backplate can be adapted to be mounted on a wall so as to be level, for example by including a bubble level on the backplate. One or more vents are preferably located on the sides of the body, such as in a gap beneath the translatably mounted ring, and/or in a gap between the head unit and the backplate. The target temperature for the device can be altered in response to sensing rotation of the rotating ring, and the programmed schedule can be displayed to and altered by the user in response to sensing rotation of the ring and the translational movement of the ring. Historical information such as temperature and cost information can be displayed to a user in response to sensing rotating of the rotating ring. One or more device settings can be displayed to and edited by a user in response to sensing rotating of the rotating member and the translational movement. According to some embodiments, text characters can be entered by the user.

An occupancy sensing electronic thermostat is described that includes a thermostat body, an electronic display that is viewable by a user in front of the thermostat, a passive infrared sensor for measuring infrared energy and an infrared energy directing element formed integrally with a front surface of the thermostat body. The passive infrared sensor may be positioned behind the infrared energy directing element such that infrared energy is directed thereonto by the infrared energy directing element. The thermostat may also include a temperature sensor and a microprocessor programmed to detect occupancy based on measurements from the passive infrared sensor.

According to one embodiment, a smart home device includes a front casing that is coupleable with a back plate to define a housing having an interior region within which one or more components of the smart home device are contained. The smart home device also includes an occupancy sensor that is disposed within the interior region of the smart home device and a button cap component that is positioned axially in front of the occupancy sensor. The button cap component is pressable by a user to actuate a switch that is disposed axially behind the button cap component. The smart home device further includes a lighting component that is positioned axially behind the button cap component. The lighting component is configured to disperse light circumferentially around the button cap component so as to provide a visual halo effect around the button cap component.

A thermostat and related methods is provided for controlling an HVAC system. The thermostat includes wiring terminals adapted and configured to make an electrical connection with an HVAC system wires such as common, heating and cooling control and return wires. The making of the connection with a common wire actuates switching open a loop of an electrical circuit used for power harvesting. According to some embodiments, the wiring terminal includes actuation of a moveable part of the terminal so as to accommodate the common wire that in turn actuates the switching open the power harvesting loop. More than one other loop can be switched. According to some embodiments, the wiring terminal can be used to automatically connect and/or disconnect Rc and Rh circuits when one or both Rc and Rh wires are present. According to some embodiments, the wiring terminal can be used for electronically sensing the presence of the HVAC system wire.

A sleek, low-profile wall-mountable thermostat for controlling an HVAC system is described. The thermostat includes a ring-shaped controller that rotates about a central axis, and an optical sensor directed away from the central axis and toward a radially inward-facing surface of the ring-shaped controller so as to accurately detect optical signals indicating controller's rotational movement.
