  • Patent number: 11181286
    Abstract: This disclosure relates to methods, systems, and devices for detecting an operational mode of a building component of an environmental control system. In some instances, the apparatus may include a sensor for outputting a signal related to a measure of power drawn by the building component. The sensor may be a current sensor associated with a power cord of an air conditioning unit. The signal output by the sensor may be received by a signal conditioning circuit for conditioning the signal received from the sensor such as, for example, by amplifying and/or filtering. A comparator may be configured to compare the conditioned signal to a specified threshold associated with an ON condition and/or an OFF condition of the building component. The apparatus may include a wireless interface configured to wirelessly transmit a determination of whether the building component is ON or OFF based on the result determined by the comparator.

  • Patent number: 10094584
    Abstract: A discrete air conditioner controller for controlling a discrete air conditioner unit servicing a building may receive an IR code, in some cases in a raw waveform format, from a handheld remote control that is associated with the discrete air conditioner unit during a programming process. The discrete air conditioner controller may associate the IR code with the discrete air conditioner unit and store the IR code and its association in memory. In some cases, the discrete air conditioner controller may transmit the IR code and its association to a central coordinator, where the IR code may be stored in the memory of the central coordinator. The IR code may be subsequently retrieved from the memory of the central coordinator and transmitted to selected discrete air conditioner controller units for use in controlling appropriate discrete air conditioner units.
