# Radiant Smart Dimmer Switch with Wi-Fi

## Overview The Legrand Radiant Smart Dimmer Switch is a Wi-Fi-enabled dimmer that lets you control and adjust lighting remotely via smartphone or voice assistant. It's designed as a direct replacement for standard wall switches and supports Matter protocol for broader smart home ecosystem compatibility.

## Standout Features - **Wi-Fi + Matter Support** — Connects directly to your home Wi-Fi network and supports Matter protocol, enabling compatibility with multiple smart home platforms (Apple Home, Google Home, Amazon Alexa, Samsung SmartThings, etc.) - **Remote Dimming Control** — Adjust brightness from your phone, tablet, or voice commands without being at the switch - **Neutral Wire Required** — Requires a neutral wire in your switch box (common in modern homes, but not all older installations have this) - **Push and Screw Terminals** — Flexible wiring options for both push-in and traditional screw connections - **Single-Gang Form Factor** — Standard wall switch size fits existing single-gang electrical boxes - **Indoor Use** — Designed for interior residential applications

## Who It's For This dimmer works well for homeowners who want smartphone and voice control over their lighting without replacing their entire smart home ecosystem. It's ideal if you already use Matter-compatible devices or are building a Matter-based smart home, and if your electrical installation includes a neutral wire at the switch location. It's also suitable for anyone wanting basic dimming automation without complex setup.

## Important Considerations

**Neutral Wire Requirement** — This is the biggest consideration. Many older homes lack a neutral wire at switch locations, which would require hiring an electrician to run new wiring. Check your switch box before purchasing to confirm you have a neutral wire available.

**Wi-Fi Dependency** — The switch relies on your home Wi-Fi network to function remotely. If your Wi-Fi goes down, remote control won't work (though the physical switch will still operate locally). Wi-Fi range and signal strength in your home matter for reliable performance.

**Compatibility Nuances** — While Matter support is valuable, actual cross-platform functionality depends on your specific hub and devices. Test compatibility with your existing smart home setup before assuming seamless integration.

**Dimmer Limitations** — Not all light bulbs dim smoothly with smart dimmers. LED bulbs in particular may flicker or not dim to very low levels depending on the bulb type and quality. Incandescent and halogen bulbs typically work better, though halogen requires proper heat management.

**Installation** — While a standard switch replacement, improper installation can create safety hazards. If you're not comfortable working with electrical wiring, hire a licensed electrician.

**Load Capacity** — Confirm the switch's wattage rating matches your fixture's total bulb wattage. Exceeding the rated load can damage the switch or create fire hazards.
