    Abstract: A two-wire load control device may be configured to compute an accurate estimate of real-time power consumption by a load that is electrically connected to, and controlled by, the two-wire load control device. The load control device may be adapted to measure a voltage drop across the device during a first portion of a half-cycle of an AC waveform provided to the device. The device may be further configured to estimate a voltage drop across the load during the second portion of the half-cycle. The estimated voltage drop may be based on the measured voltage drop. The device may be further configured to measure a current supplied to the load during a second portion of the half-cycle. The device may be configured to estimate power consumed by the load based on the measured current and the estimated voltage drop.

    Abstract: A temperature control system may include a temperature control device, an electrical wall box having a hole for passing a wire or cable into the wall box, and a gland configured to be inserted into the hole of the wall box. The temperature control device may include a temperature sensor. The wall box may be configured to be mounted to a wall. The temperature control device may be configured to be mounted to the wall box such that the temperature sensor is located within the wall box. A wire or cable may be passed from a wall cavity of the wall, through the gland once inserted into the hole of the wall box, into an interior of the wall box, and attached to the temperature control device. The gland and the wall box may be configured to prevent air within the wall cavity from entering the wall box when the wire or cable is passed into the wall box.

    Abstract: A load control system may include devices for performing communications for controlling an amount of power provided to an electrical load. The devices may include load control devices that may communicate by transmitting digital messages. A user device having an adjustable wireless communication range may be used for discovering devices, configuring devices, and/or diagnosing devices in the load control system. The user device may detect whether devices are within an established wireless communication range of one another for performing communications. The user device may detect digital messages transmitted from a device and/or digital messages received at a device to determine whether the digital messages are correctly communicated in the load control system. The user device may provide an indication to a user indicating whether a digital message is correctly transmitted or received by a device in the load control system.

    Abstract: Control-source devices may be associated with control-target devices of a load control system during a configuration procedure, such that the control-target devices are responsive to the associated control-source devices during normal operation. The configuration procedure may be executed using a network device having a visual display for associating the control-source devices and control-target devices. The control-source devices may be associated with the control-target devices on an area-by-area basis using an area configuration procedure. The control-target devices may be configured to flash a controlled lighting load according to a flashing profile during the configuration procedure. The flashing profile may be characterized by at least one abrupt transition between off and on, and at least one gradual transition between off and on, where the abrupt and gradual transitions are repeated on a periodic basis.

    Abstract: A controllable electrical outlet may be used to control one or more standard electrical outlets. The controllable electrical outlet may include a first connection configured to be electrically coupled to a hot connection, a second connection configured to be electrically coupled to a standard electrical outlet, and a third connection configured to be electrically coupled to a neutral connection. The controllable electrical outlet may also include a load control circuit, a communication circuit, and a control circuit. The load control circuit may be electrically coupled in series between the first and second screw terminals to control power delivered to the standard electrical outlet, and the control circuit may be coupled to the load control circuit and the communication circuit. The control circuit may be configured to control power delivered to the standard electrical outlet in response to a wireless signal received via the communication circuit.

    Abstract: As described herein, a wall box installation tool may include a template body, one or more hollow pegs, a guide ring, and/or one or more template cards. The template cards may be configured to be installed on a front surface of the template body. A template card may define a plurality of holes therethrough. The guide ring may be configured to be installed within a pre-drilled hole in a wall. Each template card may be associated with a respective electrical device configuration. A subset of bores extending through the hollow pegs may be accessible via the template card when the template card is installed on the front surface of the template body. The wall box installation tool may include one or more fasteners that are configured to install a template card onto the front surface of the template body.

    Abstract: A load control device may utilize a feedback signal representative of an average magnitude of the load current conducted through an electrical load to control the amount of power delivered to the electrical load. The feedback signal may be generated based on a sense signal that is electrically isolated from the line voltage input of the load control device. Depending on the operational characteristics of the electrical load, the feedback signal may be generated using different techniques. In one example technique, the sense signal may be integrated and filtered to derive the feedback signal. In another example technique, the sense signal may be used in conjunction with an input power of the load control device and an efficiency parameter of the load control device to derive the feedback signal. In yet another example technique, values derived from the foregoing two techniques may be blended together to obtain the feedback signal.
