| Alexa / Google Assistant support | Works with Amazon Alexa and Google Assistant via the Kasa app | Not positioned as an Alexa/Google Assistant device; built around Apple's HomeKit ecosystem | Households mixing Alexa or Google speakers with Apple devices need to know the HomeKit model isn't marketed as multi-ecosystem the way the standard HS220 is. source |
Verdict
Both switches do the same physical dimming job; the decision comes down entirely to which smart-home ecosystem you're already committed to. If you rely on Alexa, Google Assistant, or the Kasa app, get the HS220. If your home runs on Apple Home and Siri, the KS220 is the one built for that.
Pick Kasa Smart Dimmer Switch HS220 when
You use Alexa, Google Assistant, or the Kasa app as your smart-home hub and don't need Apple Home integration.
Pick Kasa Apple HomeKit Smart Dimmer Switch KS220 when
You control your smart home primarily through Apple's Home app and Siri and want native HomeKit support without a bridge.
The HS220 and KS220 share the same core job: an in-wall dimmer switch for single-pole or 3-way (with an add-on switch) lighting circuits. The split between them is entirely about which voice and app ecosystem they were built to plug into, not dimming performance or wiring requirements.
The HS220 is TP-Link's standard smart dimmer. It's set up and controlled through the Kasa app and integrates with Amazon Alexa and Google Assistant, making it the natural pick for households already using those platforms for lighting, plugs, or cameras.
The KS220 exists specifically to fill the Apple Home gap. Instead of the Kasa app, it's configured and controlled through Apple's Home app, and it supports Siri voice commands natively — something the HS220 cannot do without a third-party bridge, and even then imperfectly.
There isn't a 'better' switch here so much as a 'correct' one for your ecosystem. Picking the wrong one means either losing HomeKit/Siri control entirely, or giving up the unified Kasa app and Alexa/Google integration that ties your other TP-Link devices together.
