Decora Smart Controller Switch Wi-Fi 2nd Gen - Scene Control Made

In this review of the Decora Smart Controller Switch Wi-Fi 2nd Gen, the bottom line is simple: this is for homeowners who want a wall switch that adds multi-button scene control and voice integration without complicated programming. The reviewer found the switch particularly useful when replacing a standard toggle to gain three programmable scene buttons plus a wired load control that responds to Alexa, Google Assistant, or Siri. Setup via the My Leviton app is straightforward and the Apple HomeKit compatibility makes it a good fit for iOS users who already use an Apple Home Hub.

Key Features

• Multi-button control: Three top buttons can be assigned to custom lighting scenes through the app, making routine scenes like Movie Time or All Off one-tap actions.
• Built-in load switch: The bottom button provides On/Off control of a connected light or load and supports voice control with major voice assistants.
• Quick install: The switch replaces a standard wall switch and uses wire leads for a familiar wiring process, though a neutral wire is required.
• Flexible 3-way options: Supports a wired companion or an optional wire-free Anywhere Switch Companion for multi-location control without extra wiring.
• App-driven setup: My Leviton app handles scene assignment and offers options such as custom engraved buttons (US only) and IFTTT integration for advanced automations.

Who It's For

The Decora Smart Controller Switch is best for homeowners or installers who want to upgrade a single switch location to scene-capable smart control and already have a neutral in the switch box. It is especially useful for users invested in voice ecosystems or Apple HomeKit who want local scene control and the convenience of app-driven assignments.

It is less suitable for renters or locations without a neutral wire, and those wanting full dimming capability for high-current loads should confirm load ratings before purchase. Buyers who need an entirely battery-free retrofit without any wiring changes may prefer a different wireless-only scene solution.

Pros & Cons

Pros

• Easy installation and setup through the My Leviton app, with clear wiring using wire leads.
• Reliable integration with Alexa, Google Assistant, and Apple HomeKit for voice and scene control.
• Useful multi-button scene layout that turns three scene actions into single-touch controls.
• Supports wire-free or wired 3-way companions for flexible multi-location control.

Cons

• Requires a neutral wire, so it will not fit every existing switch box without additional wiring.
• Some users report mixed long-term reliability, so expect occasional connectivity troubleshooting in varied Wi-Fi environments.
