Tapo S515 Smart Light Switch, Matter-Compatible, Single-Pole/3-Way/4-Way

Key points

Control hallway, bedroom, or living room lighting from the wall, your phone, or a voice assistant with the Tapo S515. It supports single-pole, 3-way, and 4-way circuit configurations, so one light can be managed from multiple locations.

Want lighting that follows your routine as well as your commands? Set schedules in the Tapo app, use Away Mode to turn lights on and off randomly while you’re out, or group the switch with other smart devices for coordinated control.

Matter compatibility supports integration with major smart home platforms, including amazon Alexa, Apple HomeKit, Google Home, and Samsung SmartThings. The switch also tracks connected lights’ energy use in the Tapo app, where you can set an electricity rate to estimate energy costs.

For everyday decision-making, this offers more than a conventional wall switch: it adds app and voice control, scheduling, and energy tracking while retaining a wall-mounted toggle. Buyer feedback is mixed. Some customers praise responsiveness and remote control, while others report issues with Wi-Fi connection, app behavior, multi-way operation, or light flickering. These are reported experiences, not guaranteed outcomes.

Everyday use

Use the S515 for a light that needs to be controlled from more than one spot, such as at both ends of a hallway or from different points in a living room. App control is useful when you want to manage lights remotely, while schedules can align lighting with regular routines. Away Mode provides another way to vary lighting while the home is unoccupied.

The energy-monitoring feature gives you a view of connected lights’ usage in the Tapo app. You can also enter your electricity rate there to estimate energy costs. This can help you compare usage over time and make informed adjustments to your lighting habits.

Tips for day-to-day use

The switch requires neutral wiring and a 2.4GHz Wi-Fi connection for setup. Check that the intended circuit and installation point are suitable before beginning, if you’re unfamiliar with electrical wiring, use a qualified electrician. Once installed, choose app, voice, or scheduled control to suit the way you use the room. Matter-compatible devices can also be grouped with the switch for shared smart-home control.
