TP-Link Tapo Smart Switch Review: The Best Matter Light Switch

📅 July 2026 ✍️ By HomeBot Future Editorial Team ⏱️ 7 min read

Smart light switches are better than smart bulbs for whole-home lighting automation. The TP-Link Tapo S515 is our top pick, with Matter compatibility, energy monitoring, and support for all major smart home platforms. This review explains why it is the smart switch to buy in 2026.

Why Smart Switches Beat Smart Bulbs

Smart bulbs are popular, but smart switches are often a better choice for whole-home automation:

• Keep your existing bulbs — No need to replace working bulbs with expensive smart bulbs
• Wall switches still work — Family members and guests can use switches normally
• One switch controls multiple bulbs — A single smart switch can control a whole chandelier
• Lower total cost — One $25 switch vs. multiple $15 smart bulbs per room
• More reliable — Switches are hardwired, no battery or bulb pairing issues

Key Features

Matter Compatible

The Tapo S515 supports Matter, meaning it works with Alexa, Google Home, Apple Home, and SmartThings without any platform-specific setup. This is the future-proof choice.

Energy Monitoring

The switch tracks power usage of connected lights, helping you identify energy waste and verify that lights are off when not in use.

Single-Pole, 3-Way, or 4-Way Installation

The S515 supports single-pole (one switch controls one light), 3-way (two switches control one light), and 4-way (three or more switches) installations. This covers virtually any home wiring configuration.

UL Certified

UL certification ensures the switch meets safety standards for electrical devices. Important for any device handling household current.

Neutral Wire Required

The switch requires a neutral wire for installation. Most homes built after 1985 have neutral wires in switch boxes. Older homes may not — check before buying.

Who Should Buy

Buy the Tapo S515 smart switch if:

• You want Matter compatibility for future-proofing
• You want to control lights from wall switches AND smart home
• You want energy monitoring
• Your home has neutral wires in switch boxes
• You want to automate lighting without replacing bulbs

Consider alternatives if:

• Your home does not have neutral wires (consider Lutron Aurora or no-neutral options)
• You want the simplest installation (consider smart plugs instead)
• You want dimming capability (consider Tapo S510D dimmer switch)

The Bottom Line

The TP-Link Tapo S515 is the best Matter-compatible smart switch available. At $24 with energy monitoring and multi-platform support, it is excellent value. If you want to automate lighting throughout your home without replacing bulbs, this is the switch to buy.
