ScoredWant HomeKit control over your lights without buying a hub, a bridge, or anything else with a subscription attached? The Kasa KS220 does exactly one job — dimming — and does it natively through Apple's ecosystem for less than the price of a dinner out.
What It Is
The Kasa KS220 is an in-wall smart dimmer switch that replaces your existing single-pole (or 3-way, depending on wiring) light switch. It works natively with Apple HomeKit, so you control it through the Home app, ask Siri to dim the lights, or fold it into HomeKit automations and scenes — no Kasa app account or third-party hub required. It still wires into your existing electrical box like a normal dimmer, so installation follows the same basic process as swapping any switch.
Who It's For
This is built for Apple households. If you've got an iPhone, HomePod, or iPad running the Home app and want smart dimming without a Wi-Fi hub or a bridge, this fits squarely. It's also a reasonable first step into smart lighting — at under $20, it's cheap enough to try on one room without committing to a whole new app ecosystem. It's a poor fit if you're on Android, Google Home, or Alexa-first, since HomeKit-only compatibility rules out most of that audience.
Key Features & Specs
- Native Apple HomeKit support — pairs directly with the Home app, no hub needed
- In-wall dimmer switch — replaces existing wiring, works with dimmable LED, incandescent, and halogen bulbs
- Voice control — Siri commands for on/off and dimming levels
- Automation-ready — usable in HomeKit scenes, schedules, and triggers alongside other HomeKit accessories
- Physical switch functionality retained — still works as a manual dimmer if your phone's dead or a guest just wants to flip a switch
- Price — sits at the low end of the smart-switch category, around $20
Pros
- Genuinely simple for Apple users — no extra hub, bridge, or subscription fees
- Priced well below most smart dimmers in its class
- Keeps normal manual switch behavior, so it's not a smart-only gadget
- Slots cleanly into existing HomeKit automations if you already have other Apple-compatible gear
Cons
- HomeKit-only, so mixed-ecosystem households lose native Alexa/Google Assistant support
- Requires a neutral wire in most installs, which some older homes lack — check your wiring before buying
- Installation means working with your home's electrical wiring, which not everyone wants to DIY
If HomeKit already runs your home, the KS220 is a straightforward yes: no bloated app, no subscription, just a dimmer that talks to Siri and plays nice with your existing automations. If you're on Alexa or Google Home, skip it — this switch won't talk to either, and you're better off with a multi-protocol dimmer.
