Best TP-Link 3-Way Smart Light Switches (2025): HS210 vs KS230 Review & Buying Guide

Why Choose a TP-Link 3-Way Smart Switch?

If you want to control the same light from two locations say, at the top and bottom of the stairs then you need a 3-way light switch. TP-Link, through its Kasa Smart line, makes some of the most reliable, Wi-Fi-connected 3-way switches on the market.

Unlike basic mechanical switches, TP-Link’s smart switches let you:

• Turn lights on/off from two locations

• Control them via the Kasa Smart app

• Schedule lights to turn on automatically

• Use Alexa, Google Assistant, or SmartThings voice commands

Quick Pick:

For simple 3-way smart lighting, the TP-Link Kasa HS210 3-Way Kit - [Amazon Affiliate Link] is the best value.
For dimming control, go with the TP-Link KS230 3-Way Dimmer Kit - [Amazon Affiliate Link].

Understanding the “3-Way” Setup

A 3-way switch means two switches control one light fixture. For example:

• One switch at the bottom of your stairs

• One at the top controlling the same light

TP-Link’s HS210 and KS230 kits are designed to replace both switches in that setup, giving you smart control at both ends.

Pro Tip: Check that your wall box has a neutral wire (usually white). Most TP-Link switches require it to work.

Key Features That Make TP-Link Stand Out

1. No Hub Required
   Unlike some smart switches, TP-Link devices connect directly to your Wi-Fi network no extra hardware needed.

2. Voice & App Control
   Hands-free lighting through Alexa or Google Assistant adds serious convenience. You can even group lights for whole-room commands.

3. Smart Scheduling
   Automate your lighting schedule to match sunrise/sunset or your daily routine using the Kasa Smart app.

4. Reliable 3-Way Wiring Design
   The HS210 kit includes both master and slave switches to ensure the 3-way circuit works perfectly something cheaper alternatives often fail at.

Installation Tips (Before You Buy)

Installing smart switches isn’t hard—but you should follow a few steps to ensure a smooth setup:

• Turn Off Power at the breaker box before touching any wires.

• Label Your Existing Wires (line, load, travelers) before removing old switches.

• Install the “Master” Switch where the line (power in) is located.

• Use the Kasa App’s Setup Wizard to finish pairing and configuration.

• Check Wi-Fi Signal Strength—the master switch needs a good 2.4GHz signal for stable performance.

If you’re not comfortable working with household wiring, it’s best to hire a qualified electrician.

Which TP-Link 3-Way Switch Should You Choose?

• Choose the HS210 3-Way Kit:
  If you want simple on/off control and reliable smart functionality, the HS210 Kit is the perfect balance of price and performance.

• Choose the KS230 Dimmer Kit
  If you’d like to dim lights, set moods, and create soft fade-ins, go with the KS230 Dimmer Kit. It’s ideal for living rooms, bedrooms, or entertainment spaces.

Customer Reviews & Real-World Feedback

• Stable Wi-Fi connection

Some users mention that the switches are slightly bulkier than standard ones, so check box depth before installation. So far I have not had any issues and my home was built 2000. You want to make sure your ground and neutral wires do not touch when placing the switch back into the box in your wall.
