Abstract: A system that selectively provides power to a speaker light is described. This system may include: the speaker light; a power supply that provides electrical power to the speaker light when the power supply is electrically coupled to an external power source; a relay electrically coupled to the power supply and electrically coupled to a switch; and the switch, where the switch has a first state in which the switch electrically couples the relay to the external power source and a second state in which the switch electrically decouples the relay from the external power source. Moreover, the speaker light may include a master speaker light in a speaker-light array with multiple speaker lights and associated power supplies, and the master speaker light may wirelessly configure and control operation of one or more remaining speaker lights in the speaker-light array.

Abstract: A kit of parts is provided comprising a light and/or loudspeaker fitting for a smart home system. The light and/or loudspeaker fitting comprises a lighting component and/or a loudspeaker; a sensor data input interface; and a processor. The kit of parts further comprises a sensor module comprising a sensor data output interface; and one or more sensors. The light and/or loudspeaker fitting and the sensor module comprise complementary fastening means configured to detachably couple the sensor module to the light and/or loudspeaker fitting so that the sensor data output interface of the sensor module is in communication with the sensor data input interface of the light and/or loudspeaker fitting when the sensor module is coupled to the light and/or loudspeaker fitting, so as to form a sensor interface between the sensor module and the light and/or loudspeaker fitting.
