Leviton Decora Smart Switch, Wi-Fi 2nd Gen, Neutral Wire Required, Works with Matter, My Leviton, Alexa, Google Assistant, Apple Home/Siri & Wired or Wire-Free 3-Way, D215S-1RW, White

Quick take

This Leviton Decora Smart Wi‑Fi 2nd Gen switch is a neutral-wire required, hub-free option for controlling lighting through the My Leviton app and popular voice assistants. It supports Matter functionality via a firmware update, and it can be used in single-pole or 3-way locations with compatible companion switches (wired or wire-free). The main catch is compatibility, you must have a neutral wire and you need a 2.4 GHz Wi‑Fi network for setup.

Pros and cons

Pros

  • Hub-free Wi‑Fi control using the My Leviton app (2.4 GHz required).
  • Matter support can be enabled with a My Leviton app firmware update.
  • Works with voice ecosystems including Alexa, Google Assistant, and Apple Siri.
  • Built for common lighting and motor-style loads, rated up to 15A and 3/4 HP.

Cons

  • Neutral wire is required, so it may not work in homes without one.
  • Setup depends on a 2.4 GHz Wi‑Fi network, not 5 GHz.
  • 3-way control requires a compatible companion switch (wired or wire-free), not just this device alone.

What buyers think

Reviewed productBuy on Amazon

Buyer-review evidence points to a consistently smooth ownership experience, with themes around reliable connection and “it just works” operation. Setup is frequently described as easy, particularly on 2.4 GHz Wi‑Fi systems, and users often like the lack of noticeable issues such as flickering when used with supported lighting loads. Many reviewers also highlight that the switch looks at home with typical Decora-style installs, and they mention strong dimming performance for smart lighting automation and schedules. Overall, the review pattern suggests good day-to-day usability and solid integration once installed, with limited evidence to draw strong conclusions beyond these core setup and reliability themes.

What this switch does (and why people buy it)

The Leviton Decora Smart Wi‑Fi 2nd Gen is designed to replace a traditional wall switch so you can control lighting from your phone, set schedules, and use voice commands. It connects directly to your 2.4 GHz Wi‑Fi network and uses the My Leviton app, which helps if you want smart lighting without adding a separate hub.

It’s also meant for homes that care about cross-platform smart home compatibility. Matter support can be enabled through a firmware update, which can help you connect the switch with a wider set of Matter-enabled ecosystems. In addition, the switch is designed for 3-way lighting, using a compatible companion switch so you can control the same lights from two wall locations.

Key features to know before you buy

Neutral wire requirement

This model requires a neutral wire for functionality. If you are replacing an existing switch, make sure the box has a neutral conductor available, or be prepared for an electrician to verify compatibility before installation.

Wi‑Fi 2.4 GHz only, no hub required

It’s built for 2.4 GHz Wi‑Fi networks. That matters if your home uses 5 GHz only or you have separate network names. If your router supports dual-band, confirm which network will host the switch during setup.

Matter support

Matter support can be enabled with a firmware update through the My Leviton app. If you are building a Matter-based setup with ecosystems like Apple Home, Alexa, or SmartThings, this is a meaningful feature to align your lighting controls with your broader smart home strategy.

Voice and app control

You can control it using major voice assistants, including Alexa, Google Assistant, and Apple Siri. The My Leviton app supports remote control and scheduling so lights can run on routines whether you are home or away.

3-way and multi-location options

This switch supports 3-way wiring, but multi-location control requires pairing with a compatible companion switch. The system supports wired companion switches, and it also supports a wire-free anywhere companion option, which can simplify installs where adding wiring is difficult.

Performance and smart-lighting experience

Reviewed productBuy on Amazon

In review themes, buyers commonly mention dependable operation (no noticeable disconnects) and straightforward setup. Dimming is also brought up positively, which matters because not all smart switches behave well with all dimmable bulbs and fixtures.

As with any smart switch, real-world performance will depend on your specific lighting load, bulb type, and wiring conditions. The switch is rated for a range of common loads, so it’s positioned for everyday lighting, including LED and CFL use.

Pros and cons for different buyers

Best for

  • Homes that already have neutral wires available at the switch location.
  • Buyers who want smart lighting without a hub, using 2.4 GHz Wi‑Fi.
  • People looking for Matter compatibility that can be enabled after setup.
  • Anyone with a 3-way layout who plans to use the right compatible companion switch.

Consider alternatives if

  • You do not have a neutral wire available, or rewiring is not an option.
  • You only have 5 GHz Wi‑Fi available for new devices.
  • You need a multi-location solution without purchasing a companion switch for the other location.

Installation and compatibility notes

This model is a wall-mounted rocker switch designed for typical electrical boxes and standard switch replacement. It operates on 120V circuits and is rated up to 15A, and it supports control of lighting and certain motor-style loads (up to 3/4 HP). Before purchase, check that your circuit, wiring (especially neutral), and the type of load you are controlling are a match.

If you are unsure about your wiring situation, it’s worth having a licensed electrician verify neutral availability and correct wiring for safe installation. That upfront check can save time if your home wiring differs from what you expected.

Verdict

Reviewed productBuy on Amazon

The Leviton Decora Smart Wi‑Fi 2nd Gen switch is a strong fit for buyers who want hub-free smart lighting with voice control, easy app-based scheduling, and a path to Matter compatibility. It earns its place by targeting practical day-to-day use, with review themes centered on setup ease and reliable operation. If you do not have a neutral wire or your Wi‑Fi plan does not include 2.4 GHz, that limitation is likely to be the deciding factor.
