What is a system to control all light in one room called?

The term used to describe a system that controls all the light in one room is "multi-scene control." This system allows users to set different lighting scenarios or scenes that can be activated with a single command, creating an optimal ambiance for various activities such as reading, watching a movie, or entertaining guests. Multi-scene control provides flexibility and enhances user experience by allowing them to manipulate multiple light sources and their intensities simultaneously.

In contrast, while a smart dimmer can control the brightness of individual lights, it typically does not manage multiple fixtures or preset scenes. Similarly, an occupancy sensor is designed to turn lights on or off based on the presence of individuals in the room, but it does not offer the ability to create customized lighting scenes. A channel is not a relevant term in this context, as it usually refers to a pathway in a lighting control system rather than a system to control lights in a room comprehensively.
