A smart light switch is a device that replaces a traditional light switch and allows you to control your lights through voice commands, a home automation system or a smartphone app. Smart light switches work by connecting to your Wi-Fi network and can be programmed to turn lights on and off automatically, dim the lights, or change the colour of the lights.

With a smart light switch, you can remotely control your lights from anywhere, monitor energy usage, and set schedules or routines to save energy. Some smart light switches also have the capability of being integrated with motion sensors and other smart devices in your home, such as speakers, thermostats, or security cameras.
