An automated luminaire includes a head that includes a light source. The head is rotatable about a tilt axis and about a pan axis. The automated luminaire further includes a first pan absolute encoder, a second pan absolute encoder, and a controller configured to determine a pan position of the head. The controller is configured to determine the pan position of the head based on first rotational position information received from the first pan absolute encoder and second rotational position information received from the second pan absolute encoder.

This disclosure discloses a light-emitting device control method. A terminal device obtains and displays a target splicing shape on a control interface; records the configuration parameters of the virtual control in response to a configuring operation of a selected virtual control in the target splicing shape; determines a sorting value of the virtual control in the target splicing shape; obtains the control information according to the configuration parameters and sorting value, and sends the control information to the controller. The controller receives the control information sent by the terminal device, and controls the lighting of the target light-emitting module according to the control information. The control method provided by this disclosure can avoid the operation of establishing communication connections between all light-emitting modules and the terminal device, improving control efficiency and reducing production costs at the same time.

A control device may include an analog intensity adjustment actuator that is configured to be manually operated to adjust an intensity level of a lighting load. The control device may include a communication circuit configured to receive a message from a remote device. The message may include a commanded intensity level. The control device may include an actuator adjustment system configured to adjust a position of the analog intensity adjustment actuator and a control circuit configured to control the amount of power delivered to the electrical load in response to manual operation of the analog intensity adjustment actuator. The control circuit may be further configured to control the actuator adjustment system to adjust the position of the analog intensity adjustment actuator in response to the message received from the remote device. The position of the analog intensity adjustment actuator may be adjusted to indicate the commanded intensity level.

Various systems and methods related to smart-home networking are presented. A low-power smart home device may be exclusively battery powered. The low-power smart home device may transmit data via a low-power communication protocol to a spokesman smart home device. The spokesman smart home device may receive the data transmitted via the low-power communication protocol. The spokesman smart home device may be a doorbell, a thermostat, a hazard detector, or a wall switch. The spokesman smart home device may connected to household wiring that provides power. The spokesman smart home device may translate the data from the low-power communication protocol to a relatively high-power communication protocol. The spokesman smart home device may transmit the data, via the relatively high-power communication protocol, to a cloud-based server system.

Photographic lighting devices, systems, and methods having multiple electrical energy storage/discharge (EESD) elements and/or multiple light sources in a single photographic lighting device to perform one or more photographic lighting effects. Multiple EESD elements and multiple light sources can be configured to have two separate light emissions occur in a single image acquisition window. In one exemplary aspect, independent control of one or more light sources connected to a first EESD bank and another one or more light sources connected to a second EESD bank, such as via control circuitry, may be utilized in producing various lighting effects.

A two-way load control system comprises a power device, such as a load control device for controlling an electrical load receiving power from an AC power source, and a controller adapted to be coupled in series between the source and the power device. The load control system may be installed without requiring any additional wires to be run, and is easily configured without the need for a computer or an advanced commissioning procedure. The power device receives both power and communication over two wires. The controller generates a phase-control voltage and transmits a forward digital message to the power device by encoding digital information in timing edges of the phase-control voltage. The power device transmits a reverse digital message to the controller via the power wiring.

In various embodiments, a hazard detector may be presented. The hazard detector may include at least one hazard detection sensor that detects a presence of at least one type of hazard. The hazard detector may include a speaker, a light, and a motion detection sensor that detects motion in an ambient environment of the hazard detector. A processing system of the hazard detector may be configured to select an illumination state based on a determined status. The processing system may cause the light to illuminate based on the selected illumination state. The processing system may determine a gesture has been performed in the ambient environment of the hazard detector following the light being illuminated based on the selected illumination state. The processing system may output a detail of the status via the speaker corresponding to the illumination state in response to determining the gesture has been performed.

An energy control network may include a number of load control devices, such as dimmer switches, multi-button selector switch, occupancy sensors, and remote controllers, among others. These load control devices may be configured for wireless communication. Other wireless devices, such as laptops, tablets, and smart cellular phones may be configured to communicate with the load control devices of the energy control network. The load control devices and the other wireless communication devices may also be configured for Near Field Communication (NFC). NFC may be used to provide a load control device with its initial default configuration and/or an application specific configuration. Also, NFC may be used to transfer a configuration from one load control device that may have become faulty, to a replacement load control device. And NFC may be used to provide and trigger commands that may cause a load control load device to operate in a predetermined manner.

Various arrangements for assessing an installation of a smart home device are presented. An orientation of the smart home device may be analyzed to determine whether the orientation of the smart home device is unsuitable for one or more features of the smart home device to function properly. An indication of whether the orientation of the smart home device is unsuitable may be output, such as by the smart home device using voice or lighting.
