Leviton’s smart home lineup is extensive, but older homes often get left behind due to missing neutral wires. The Decora Smart No-Neutral Dimmer directly solves that. It’s a retrofit-focused switch that lets you add dimming control where traditional smart switches can’t install. You will need the company’s separate Wi-Fi Bridge for connectivity, which is a crucial upfront cost to factor in.

In daily use, the dimmer operates reliably. The physical rocker gives satisfying tactile feedback for manual control, while the My Leviton app handles schedules and remote access smoothly. It handles standard 120V AC dimmable bulbs, and the automatic operation mode means it just works once set up—no need to fiddle with settings each time you turn on the lights. The dimming curve is smooth, without any jarring flicker or sudden jumps in brightness.

This is a specific tool for a specific problem. If your switch boxes have neutral wires, you have simpler and often cheaper options. But for pre-1980s wiring, this dimmer is a clean, professional-grade solution. Just remember the required bridge adds to the total investment.
