Abstract: A user-friendly programmable thermostat is described that includes receiving an immediate-control input to change set point temperature, controlling temperature according to the set point temperature for a predetermined time interval, and then automatically resetting the set point temperature upon the ending of the predetermined time interval such that the user is urged to make further immediate-control inputs. A schedule for the programmable thermostat is automatically generated based on the immediate-control inputs. Methods are also described for receiving user input relating to the user's preference regarding automatically generating a schedule, and determining whether or not to automatically adopt an automatically generated schedule based on the received user input.

Abstract: Embodiments of the present invention provide a temperature control system having programmable, interchangeable docking thermostats that work cooperatively to achieve desired temperature control in an enclosure. Various embodiments provide first and second thermostats each having one or more temperature sensors. Also provided may be a first HVAC docking device directly wired to the HVAC wire system and a second docking device that may connect to a power source other than the HVAC wire system, where each of the docking devices have an electrical connector mateable to the electrical connector of the docking thermostats. The first and second docking thermostats may interchangeably mate to the docking devices, and either may control the HVAC system to achieve a desired comfort level.

Abstract: A thermostat may include a user interface configured to display at least a first graphical display and a second graphical display, a first proximity sensor having a first responsive range, and a second proximity sensor having a second responsive range. A processing system may be programmed to control the user interface by receiving an indication of a user presence within the second responsive range from the second proximity sensor while not receiving an indication of a user presence within the first responsive range from the first proximity sensor and causing the user interface to display the second graphical display. The processing system may also be programmed to receive an indication of a user presence within the first responsive range from the first proximity sensor and an indication of the user presence within the second responsive range from the second proximity sensor and cause the user interface to transition from the second graphical display to the first graphical display.

Abstract: HVAC schedules may be programmed for a thermostat using a combination of pre-existing schedules or templates and automated schedule learning. For example, a pre-existing schedule may be initiated on the thermostat and the automated schedule learning may be used to update the pre-existing schedule based on users' interactions with the thermostat. The preexisting HVAC schedules may be stored on a device or received from a social networking service or another online service that includes shared HVAC schedules.

Abstract: A particular smart hazard detector may itself function as a guide during a process of installation of the same at an installation location. Additionally, the installation location of the particular smart hazard detector may play a central role in how various settings of the smart hazard detector are defined and adjusted over time.

Abstract: include using an application on a mobile device to establish first wireless communications with a first hazard detector that was previously paired with the user account. The method may also include transmitting, to the first hazard detector and using the first wireless protocol, a transmission that instructs the first hazard detector to establish second wireless communications with a second hazard detector, where the second wireless communications use a second wireless protocol. The method may additionally include transmitting network credentials to the first hazard detector using the first wireless protocol, where the credentials are then sent from the first hazard detector to the second hazard detector using the second wireless protocol, such that the second hazard detector can pair with the user account using the first wireless protocol.

Abstract: Ambient amount of a hazardous condition may be monitored. A mode may be set to a state indicative of the hazardous condition being present in the ambient environment. It may then be determined that the amount of the hazard in the ambient environment has dropped below an alarm criterion. A time period may then be tracked during which the amount of the hazardous condition present in the ambient environment of the hazard detector has remained below the alarm criterion. It may be determined that the time period has reached at least a threshold duration, during such time period the amount of the hazardous condition present in the ambient environment of the hazard detector having remained below the alarm criterion. An indication of the hazardous condition easing may be output in response to the time period being at least the threshold duration.

Abstract: A thermostat user interface for a network-connected thermostat is described. The thermostat includes a frustum-shaped shell body having a circular cross-section and a sidewall extending between first and second ends, the second end being user-facing when the thermostat is wall-mounted; a circular rotatable ring being user rotatable for adjusting a setting of the thermostat; and a circular cover including a clear circular center portion surrounded by a painted outer portion. The clear circular center portion permits a corresponding circular portion of a non-circular dot-matrix color display element to be visible through the circular cover and the painted outer portion masks a remaining portion of the non-circular dot-matrix color display element so as to create a circular graphical user interface.

Abstract: 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.

Abstract: 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.

Abstract: A thermostat is described that includes a rechargeable battery, a graphical user interface and a wireless network communication capabilities. During installation, in cases where the rechargeable battery is below a first threshold, the installation procedure is limited so as to avoid energy intensive installation steps which may not be supported by the low battery level. An example of an installation step that is avoided due to low battery level is set up of wireless communication. According to some embodiments, if the battery level is very low during initial installation, the installation process is halted while the battery is charged. An indication such as a flashing LED may be displayed so as to indicate to the user that the battery is being charged.
