Overview
The Kasa HS200 is a Wi-Fi smart light switch that replaces a standard single-pole toggle switch, letting you turn connected lights or fixtures on and off from the Kasa app, a schedule, or Alexa and Google Assistant voice commands.
It needs a neutral wire and a 2.4GHz Wi-Fi network, and unlike hub-based systems it talks to Wi-Fi directly, so there is no separate smart-home hub to buy. Reviewers largely used it for remote or convenience control of garage and exterior lights rather than dimming, since this is an on/off switch, not a dimmer.
- 2.4GHz Wi-Fi, no hub required
- Works with Alexa and Google Assistant
- Timer, countdown, and away-mode scheduling
- UL certified single-pole switch
Who it's for
Fits anyone replacing a single-pole toggle switch who wants app, schedule, or voice control without adding a hub. It is not for 3-way circuits with two physical switches, and it will not work where there is no neutral wire in the box.
What buyers say
From Amazon customer reviews.
Buyers consistently call installation straightforward once a neutral wire is confirmed, and several used it to control garage or exterior lights remotely from the Kasa app. Multiple reviewers praised the direct Alexa and Google Assistant integration without a separate hub. One long-term owner initially downgraded their rating after the switches failed to reconnect following a power outage, then noted TP-Link corrected the issue in a later firmware update. Another reviewer flagged that the switch is strictly single pole, not a 3-way replacement.
Strengths and trade-offs
Drawn from this product's published specifications.
- Installs in place of a standard toggle switch
- No separate smart-home hub required
- Works with Alexa and Google Assistant for voice control
- Scheduling and away mode for lights left on
Performance notes
Once wired in, the switch connects straight to a 2.4GHz Wi-Fi network rather than a separate smart-home hub, so setup happens entirely inside the Kasa app. It supports on/off scheduling, a randomized away mode, and voice commands through Alexa or Google Assistant, but it does not dim, since it is built as a single-pole on/off switch only.
