Wiring and Ecosystem Comparison
Wiring requirement
The Leviton Decora Smart Voice Dimmer requires a neutral wire for installation. This means it needs the white wire in your wall box to complete the circuit. If your home lacks this wire, this model will not work without an adapter. In contrast, the Leviton Decora Smart No-Neutral Dimmer is designed for homes without neutral wiring. It connects only to line, load, and ground wires. This makes the No-Neutral model easier to install in older houses where neutral wires are often missing from switch boxes.
Smart home compatibility
The Voice Dimmer works with Alexa and Google Assistant. It does not support Apple Home. The No-Neutral Dimmer offers broader integration. It works with Alexa, Google Assistant, and Apple Home. You must use the required MLWSB Decora Smart Wi-Fi Bridge to enable Apple Home and other platforms like SmartThings and Sonos. If you use an iPhone or rely on Apple Home, the No-Neutral model provides the necessary connectivity. The Voice Dimmer excludes this ecosystem entirely.
Built-in voice control
The Leviton Decora Smart Voice Dimmer features Alexa built directly into the device. You can ask it to dim lights, play music, or check the weather without needing a separate speaker. The No-Neutral Dimmer lacks this built-in voice hardware. It relies on external voice assistants connected via the Wi-Fi bridge. If you want to control lights with your voice directly from the switch without a hub speaker, the Voice Dimmer is the only option here. The No-Neutral model requires additional external devices for voice commands.
Multi-location wiring
Both switches support multi-location setups, but they use different methods. The Voice Dimmer supports wired 3-way dimming. You can add up to four remote DD00R or DD0SR units. This requires running additional wires between switches. The No-Neutral Dimmer supports wireless multi-location control. You can pair it with optional Anywhere Dimmer Companion (DAWDC) or Switch Companion (DAWSC) units. This allows for wire-free 3-way setups, which is easier if you cannot run new wires between walls. The No-Neutral model offers more flexible installation for existing wiring.
Physical dimensions
The Voice Dimmer measures 2 inches in width, 4 inches in height, and 1.35 inches in length. It weighs 8 ounces. The No-Neutral Dimmer is slightly narrower at 1.7 inches wide, 4.13 inches tall, and 1.4 inches deep. It weighs 9.34 ounces. Both fit standard single-gang wall boxes. The No-Neutral model is marginally thinner and lighter, but the difference is small. Both are white and designed for similar aesthetic integration. The width difference is negligible for most installations.
