The 7 Best Dimmer Smart Switches of 2026

The Kasa HS220 Smart Dimmer Switch is designed for homeowners looking to modernize their lighting with smart features. This single-pole device requires a neutral wire and connects via 2.4GHz Wi-Fi, making it perfect for those with standard wiring who want no-hub control through the Kasa app, Alexa, or Google Home.

Users appreciate the intuitive app-guided install, though consulting an electrician is advised for safety.

Build quality is solid with compact dimensions that fit standard wall boxes, and UL certification ensures peace of mind. The switch supports up to 2.5A at 120V, handling most LED and incandescent bulbs smoothly. While it lacks Matter or HomeKit support, its performance with major assistants is reliable and responsive.
