Technology for use by a human user in a viewing environment that includes a plurality of Internet of Things (IoT) light sources. Responsive to a voice command from a human user, machine logic determines which Internet of Things (IoT) light sources (for example, fixed brightness lamps, adjustable brightness lamps, windows with adjustable covers or shades) are causing glare problem by simulating a voice command throughout the entirety of a viewing environment. Once the problem light source(s) are determined, then the lighting is automatically adjusted to fix the glare problem.

A lighting system for an electrical device includes one or more light sources coupled to an electrical outlet. The one or more light sources are configured to receive power from a power supply and configured to generate output light on at least one side edge of the electrical device. The lighting system includes a controller communicatively coupled to the one or more light sources. The controller is configured to receive a signal from an auxiliary unit and control the one or more light sources to operate between an on-state and an off-state responsive to the signal from the auxiliary unit.

The invention relates to a system (1) for assisting a user in configuring a lighting system (10), in which the lighting system comprises a lighting device (15-17) and a switch (34,35) for providing power to the lighting device. The system is configured to receive at least one signal, determine from the at least one signal that the lighting device has recently been power switched, and determine whether a user-defined power-switch light setting has been set for the lighting device. The power-switch light setting is a light setting that is activated when the lighting device is power switched. The system is further configured to provide a notification to a user in dependence on the lighting device having recently been power switched and no user-defined power-switch light setting having been set for the lighting device. The notification recommends the user to set the user-defined power-switch light setting for the lighting device.
