Hazardous or dangerous conditions may be monitored. A mode may be set to a state indicative of the condition being present. It may then be determined that the hazardous or dangerous condition has eased. An indication of the hazardous or dangerous condition easing may be output in response to the determination. Such an indication may be output as synthesized speech.

Various arrangements are presented for controlling a night light feature of a hazard detector. A user interface application executed on a mobile device may output, a graphical interface that provides an option to enable a night light feature of the hazard detector. The application may transmit data indicative of the night light feature being enabled and of an associated user account to a computer server system. The computer server system may receive and store data indicative of the night light feature being enabled and of the user account. The hazard detector may receive from the computer server system data indicative of the night light feature of the hazard detector being enabled by the application. The hazard detector may enable the plurality of LEDs to provide illumination in response to the received data indicative of the night light feature of the hazard detector being enabled by the application.

A load control system may include load control devices for controlling power provided to an electrical load. The load control devices may include a control-source device and a control-target device. The control-target device may control the power provided to the electrical load based on digital messages received from the control-source device. A user device may discover load control devices when the load control devices are within an established range associated with the user device. The user device and the load control devices may communicate via a wireless communications module. The established range may be adjusted based on the configurable transmit power of the user device or the wireless communications module associated with the user device. A discovered control-target device may be associated with a control-source device to enable the control-target device to control the power provided to the electrical load based on digital messages received from the control-source device.

Various methods and systems for smart home devices are presented. Such smart home devices may include one or more environmental sensors that are configured to detect the presence of one or more environmental conditions. Such smart home devices may include a light comprising a plurality of lighting elements. Such a light may be configured to illuminate using a plurality of colors and, possibly, a plurality of animation patterns. Such smart home devices may include a processing system configured to cause the light to illuminate using the plurality of colors and the plurality of animation patterns in response to a plurality of states of the smart home device.

A load control system may include a load control device for providing power to an electrical load and a control device that may send instructions to the load control device for providing the power to the electrical load. The control device may communicate with the load control device using a link address assigned to the load control device. The load control device may provide power to the electrical load in a manner that causes the electrical load to indicate the link address assigned to the load control device. The link address may be identified by a user or a user device. The identified link address may be associated with a load control device identifier that may identify a physical location of a load control device that is assigned the link address. A user may control a load control device at a physical location by sending instructions via the link address.

A location determination method is provided for a terminal device. The method includes obtaining at least two state images of a lighting system; determining profile information of the lighting system based on state changes of the lighting system in the at least two state images; based on configuration information of the lighting system, dividing the profile information to determine a location distribution of each lighting unit in the profile information; and displaying the profile information and the location distribution of the lighting units on a control interface of the terminal device. The configuration information includes at least one of a setting number of lighting units of the lighting system, a setting length of the lighting units, a setting shape of the lighting units, and a setting size of the lighting units.

The invention relates to a mirror device (101) having a mirror surface (1), at least one light source (2), a control device (3), and first and second control elements (4, 18) connected to the control device (3) via a cable. The light source (2) is operable by the first and second control elements (4, 18). By means of the first control element (4), a first illumination mode (5) of the light source (2) can be switched on and off. By means of the second control element (18), a second illumination mode (6) of the light source (2) can be switched on and off. The first illumination mode (5) is a night light mode and in particular has a lower blue light component than the second illumination mode (6). The first illumination mode (5) differs from the second illumination mode (6).

A system (1) for determining a suitability of an input modality (36) for providing a user command for controlling at least one lighting device (31) is configured to receive a signal indicative of the user command for controlling the at least one lighting device. The user command is provided by a user (69) using the input modality. The system is further configured to determine a suitability rating for the used input modality in relation to the user command, determine one or more further suitability ratings for one or more further input modalities (19, 37, 38) in relation to the user command, compare the suitability rating with the one or more further suitability ratings, and output information specifying an input modality recommended in relation to the user command. The recommended input modality is selected from the one or more further input modalities and has a further suitability rating which is higher than the suitability rating.

A solid-state auxiliary lamp includes a lamp head having a plurality of LED modules; a thermoelectric cooler coupled to the LED modules; and a drive unit. The drive unit can include a plurality of current sources, each of the current sources coupled to a corresponding LED module; and a processor coupled to the current sources and configured to control each current source to control the light output of each current source's corresponding LED module.

A load control system may be configured using a graphical user interface (GUI) software. The GUI software may be implemented to collect control devices and add the control devices to the load control system for configuration. Programming data may be automatically determined for the added control devices based on the type of control device, the location of the control device, and/or the load type controlled by the control device. The programming data may include control settings for a scene, a schedule, or an automated control feature. The programming data may be displayed for being viewed and/or adjusted by a user. The programming data may be transmitted to the control devices and/or a system controller for being implemented in performing load control.
