Abstract: A light switch adapter with slight modification to an existing wall light switch turns the existing wall light switch into a smart device by replacing the existing screws with elongated screws. To further secure the adaptation, each of the elongated screw may contain an adapter screw head or fastener or knobbed protrusion that firmly couples the light switch adapter through an opening of the rear side of the light switch adapter. In another embodiment, the opening contains or shaped as a circlip or a C-clip that allows the adapter screw head snap into the opening securely.
