Abstract: A method may include operating a switching circuit in an on state and an off state to actuate a flow of electrical power through a load when switched to the on state; monitoring an electrical property associated with the switching circuit; receiving an enable signal from a processor to power the load; providing a drive signal to the switching circuit to switch to the on state and power the load; determining if an electrical anomaly is present based on the monitored electrical properties; causing the switching circuit to switch to the off state if an electrical anomaly is detected; providing a fault signal to the processor; determining while the switching circuit is off, if the electrical anomaly has been corrected; and after the anomaly has been corrected, causing the switching circuit to switch to the on state.

Abstract: A method of harvesting power from a heating, ventilation, and air conditioning (HVAC) system using an HVAC controller may include harvesting power from the HVAC system and measuring an electrical characteristic of the HVAC controller. The electrical characteristic may indicate whether the power harvested from the HVAC system is high enough to risk interfering with a normal operation of the HVAC system. The method may also include increasing the power harvested from the HVAC system until the electrical characteristic indicates that the HVAC controller is at risk of interfering with the normal operation of the HVAC system.

Abstract: Methods and systems facilitate network communications between a wireless network-connected thermostat and a cloud-based management server in a manner that promotes reduced power usage and extended service life of an energy-storage device of the thermostat, while at the same time accomplishing timely data transfer between the thermostat and the cloud-based management server for suitable and time-appropriate control of an HVAC system. The thermostat further comprises powering circuitry configured to: extract electrical power from one or more HVAC control wires in a manner that does not require a “common” wire; supply electrical power for thermostat operation; recharge the energy-storage device (if needed) using any surplus extracted power; and discharge the energy-storage device to assist in supplying electrical power for thermostat operation during intervals in which the extracted power alone is insufficient for thermostat operation.

Abstract: A thermostat includes a plurality of HVAC (heating, ventilation, and air conditioning) wire connectors for receiving a plurality of HVAC control wires corresponding to an HVAC system. The thermostat also includes a thermostat processing and control circuit operative to at least partially control the operation of the HVAC system and a powering circuit coupled to the HVAC wire connectors and configured to provide an electrical load power to the thermostat processing and control circuit. The thermostat includes circuitry and methods for maximizing efficiency of energy harvested from the HVAC system connected to the thermostat, and depending on which system is connected to the thermostat, different power schemes can be implemented in order to obtain power from the HVAC system.

Abstract: A method of automated sensing of an electrical anomaly associated with a thermostat may include switching a switching circuit within the thermostat to an on state. The switching circuit may be configured to activate an HVAC function when switched to the on state. The method may also include monitoring one or more electrical properties associated with the switching circuit. The method may additionally include determining if an electrical anomaly is associated with the switching circuit based at least in part on the monitored one or more electrical properties. The method may further include switching the switching circuit to an off state if an electrical anomaly is detected.

Abstract: Systems and methods for interfacing a hazard detection device with a control panel system via a dongle are provided. The dongle may be configured to alternate between drawing first and second amounts of power from the control panel system in response to the hazard detection device alternating between operating in a normal mode when no hazard is detected and an alarm mode when a hazard is detected. The hazard detection device may operate independently of any characteristics of the control panel system. For example, the hazard detection device may operate without drawing any power from the control panel system. Therefore, the dongle may allow for various types of hazard detection devices to interface with a common two-line power control system.

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.
