Kasa Smart Wi-Fi Light Switch HS200

4.5

$15.99as of Jun 7

The Kasa HS200 is the best-value smart switch: SafeWise calls it the sweet spot of price, performance, and reliability for most homeowners, and it carries a 4.5/5 average across thousands of Amazon ratings. At $20 or less with no hub required, it's the easy pick for newer homes with neutral wires. The trade-offs are no dimming, no HomeKit, and a required neutral wire.

Strengths

— Excellent value — typically $20 or less per switch
— No hub required; connects directly over Wi-Fi
— Easy DIY installation and a mature, reliable Kasa app

Watch-outs

— Requires a neutral wire (rules out many older homes)

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.

The catches are a required neutral wire, a higher price than budget Wi-Fi switches, and a firmware update to enable Matter.

— No hub required; connects directly over Wi-Fi
— Slim profile fits crowded in-wall electrical boxes

Watch-outs

— Requires a neutral wire

How they stack up

Kasa Smart Wi-Fi Light Switch HS200

The budget value pick. Cheaper and hub-free compared to the Lutron Caséta Smart Dimmer PD-6WCL, but it requires a neutral wire the Lutron and GE CYNC dimmer don't, and unlike the Leviton Decora Smart D215S and TP-Link Tapo S505D it's a basic on/off switch with no dimming or Matter on the base model.

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.
