Abstract: A smart switch system and method are disclosed. The system includes a smart switch device and a cover plate. Further, the smart switch device includes a capacitive touch surface enabling a user interaction without physical pressure application and a dimmable light source within a front panel of the smart switch device. Further, the smart switch includes a mesh networking capability for a seamless communication with a plurality of devices, a rear connector facilitating integration with a plurality of custom sensor clusters, and a control unit for adjusting brightness levels of a dimmable light source based on the user interaction with the capacitive touch surface. Additionally, the cover plate includes a plurality of sensor clusters interchangeably connectable to the smart switch device with a cable.
