It talks Clear Connect to a Lutron hub, dims up to 150 W of LED, and remembers the last level after a power cut. The TP-Link Kasa HS220 is the hub-free alternative when a neutral is present: 2.4 GHz Wi-Fi, app fade speeds, a 2 year warranty and no Apple Home. Pick the Lutron Caseta Original Smart Dimmer Switch for older wiring or a Caseta system. Pick the TP-Link Kasa HS220 for one dimmable circuit and nothing else to install.

What the differences mean

Neutral and radio

The Lutron Caseta Original Smart Dimmer Switch needs no neutral and no Wi-Fi. It uses Clear Connect to a Lutron hub, so the lights can keep responding when the router is down. The TP-Link Kasa HS220 needs a neutral and joins 2.4 GHz Wi-Fi directly, which is why it wins connectivity, and it is not smart without that network.

How much they can dim

The Lutron Caseta Original Smart Dimmer Switch is rated to 600 W of incandescent or halogen and 150 W of dimmable LED or CFL. The TP-Link Kasa HS220 is rated to 300 W incandescent and 150 W LED or CFL at 2.5 A. Both are 120 V single dimmers, so the gap shows up on a heavier incandescent load, not on a typical LED lamp.

What returns after an outage

The Lutron Caseta Original Smart Dimmer Switch has power-off memory and comes back to the previous level. The TP-Link Kasa HS220 has no power-off memory and no setting for the state after a cut. It does let you adjust or switch off the status LED, which the Lutron green LEDs do not allow.

Assistants and warranty

Through its hub, the Lutron Caseta Original Smart Dimmer Switch reaches Alexa, Google Home, Apple Home, SmartThings and Home Assistant. Matter is not supported, and the warranty is 1 year. The TP-Link Kasa HS220 reaches Alexa, Google Home, SmartThings and Home Assistant with no hub, skips Apple Home and Matter, and carries a 2 year warranty.

What owners say

Owners of both dimmers praise how the light actually behaves once it is in, then they describe different kinds of setup pain. Lutron Caseta Original Smart Dimmer Switch owners talk about years without dropouts, often across dozens of switches, and they credit Clear Connect for ignoring router reboots. They also say the hub is a separate purchase, the wallplate is not included, some LEDs hum on two-wire dimming, and the green LEDs cannot be dimmed. TP-Link Kasa HS220 owners single out a guided install with wire labels and a calibration pass that stops LED flicker, plus fade speeds they set themselves. Their warnings are the neutral, single-pole only wiring, and a deep body in a crowded box.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
