Our verdict

A sensible buy for mixed smart home setups thanks to Matter's cross platform support, provided the wall box actually has a neutral wire to work with.

Overview

A two pack of Matter certified smart light switches from TP-Link's Tapo line, built for single pole circuits with a neutral wire. Matter support means the same switch can be managed from Apple Home, Alexa, Google Home, or Samsung SmartThings instead of locking into one ecosystem.

The standout here is Matter's local control: paired Matter devices on the same network can talk to each other directly, so switching a bulb does not have to round trip through a cloud service. That also enables multi-admin use, where the same switch can be turned on from a Samsung phone, dimmed by Alexa, and turned off from an iPad, all without conflict. The catch is that it requires a neutral wire, which some older home wiring lacks.

  • Matter certified single pole switch
  • Works with Alexa, Google Home, Apple Home, SmartThings
  • Neutral wire required
  • Sold as a 2-pack, UL certified

Who it's for

Suits households running more than one smart home platform, or anyone who wants to avoid being locked into a single voice assistant down the road. It is not for outlets or switch boxes without a neutral wire, and the seller recommends an electrician if you are unsure about the wiring.

Pros and cons

Pros
  • Matter certified, works across Alexa, Google Home, Apple Home, and SmartThings
  • Local network control keeps working if internet is down
  • Multi-admin lets several apps control the same switch
  • Sold as a 2-pack, UL certified with 2 year warranty
Cons
  • Requires a neutral wire, not for every switch box
  • 2.4 GHz Wi-Fi only for the app-guided setup step

Performance notes

Matter lets the switch communicate directly with other Matter devices on the local network rather than routing every command through the cloud, which keeps basic on and off control working even if the internet connection drops. The Tapo app walks through setup, and the switch is UL certified with a 2 year warranty and rated for 100-120 VAC, 15A.
