Ranked #3 in Best Smart Light Switches

Leviton Decora Smart Wi-Fi Switch D215S

4.4

$45.84as of Jun 7

The Leviton Decora Smart D215S is the best Matter switch: it works across every major ecosystem simultaneously, needs no hub, and fits crowded electrical boxes thanks to its slim profile. Reviewers praise its Matter compatibility as game-changing, and it carries a 5-year warranty. The catches are a required neutral wire, a higher price than budget Wi-Fi switches, and a firmware update to enable Matter.

Strengths

— Matter-certified — works across Alexa, Google, Apple Home, and SmartThings
— No hub required; connects directly over Wi-Fi
— Slim profile fits crowded in-wall electrical boxes

Watch-outs

— Requires a neutral wire
— Pricier than budget Wi-Fi switches at around $50
— Matter requires a firmware update via the My Leviton app

How they stack up

Leviton Decora Smart Wi-Fi Switch D215S

The best Matter on/off switch. It adds the Matter and HomeKit support the Kasa HS200 lacks and the modern look the Lutron Caséta Smart Dimmer PD-6WCL misses, while staying hub-free. Like the Kasa it requires a neutral wire (unlike the no-neutral Lutron and GE CYNC dimmer), and unlike the TP-Link Tapo S505D it's on/off rather than a dimmer.

Lutron Caséta Smart Dimmer PD-6WCL

The reliability benchmark. It out-performs the Wi-Fi-based Kasa HS200, Leviton Decora Smart D215S, TP-Link Tapo S505D, and GE CYNC dimmer on consistency thanks to its dedicated Clear Connect RF, and like the GE CYNC it needs no neutral wire — but unlike all of them it requires the Lutron hub and skips Matter.
