Key differences between Lutron Caseta Original Smart Dimmer Switch and TP-Link Kasa HS220

A summary of selected recorded differences between these wall switches. Check the full specification table below for details and conditions.

Feature differences among your selected devices

2.4 GHz Wi-Fi (connectivity): Lutron Caseta Original Smart Dimmer Switch — No (The dimmer talks to the Lutron Smart Hub, Pico remotes and motion sensors over Lutron's own Clear Connect RF technology instead of Wi-Fi, which is why the lights keep responding when the router is down); TP-Link Kasa HS220 — Yes (IEEE 802.11b/g/n, 2.4GHz 1T1R).
Adjust Status Led (features): Lutron Caseta Original Smart Dimmer Switch — No (Lutron documents the LED behaviour on this model as fixed, with no brightness setting or off option (the newer Diva line uses an adjustable light bar instead)); TP-Link Kasa HS220 — Yes (LED Status is a configurable entry in the Kasa app's Device Settings page).
Power Off Memory (features): Lutron Caseta Original Smart Dimmer Switch — Yes (Power failure memory: if power is interrupted, the control returns to the level it was set to before the interruption); TP-Link Kasa HS220 — No (TP-Link states the default-on option exists in its smart bulbs but not in its plugs or smart switches).
Neutral Required (power): Lutron Caseta Original Smart Dimmer Switch — No (Two-wire dimmer designed for retrofit, so no neutral wire is needed in the wallbox); TP-Link Kasa HS220 — Yes (A neutral wire in the wall box is required, and the switch works in single pole wiring only).

Specifications to check side by side

Alexa (integrations): Lutron Caseta Original Smart Dimmer Switch — Lutron Hub required (Lutron lists Amazon Alexa among the platforms Caseta works with, through the Lutron Smart Hub); TP-Link Kasa HS220 — Yes.
Apple Home (integrations): Lutron Caseta Original Smart Dimmer Switch — Lutron Hub required (Lutron states the smart hub itself contains Apple Home technology, so Siri controls the lights once the dimmer is paired to it); TP-Link Kasa HS220 — No (TP-Link's own model comparison lists the HS220 as compatible with Alexa and Google Home only, while its HomeKit dimmer (KS220) is listed as HomeKit/Alexa/Google Home).
Google Home (integrations): Lutron Caseta Original Smart Dimmer Switch — Lutron Hub required (Lutron lists Google Assistant among the platforms Caseta works with, through the Lutron Smart Hub); TP-Link Kasa HS220 — Yes.
Home Assistant (integrations): Lutron Caseta Original Smart Dimmer Switch — Lutron Hub required (The core Lutron Caseta integration talks to the Lutron Caseta Smart Hub (L-BDG2-WH) and exposes wall dimmers as lights); TP-Link Kasa HS220 — Yes (The official Home Assistant TP-Link integration lists HS220 among its supported Kasa wall switches).
