10 models to compare

Does a smart light switch need a neutral wire?

Nine of ten do. The DNKIT, a dimmer sold with its own Wi-Fi bridge, is the lone Leviton option without one.

A neutral gives you seven Wi-Fi models or two Z-Wave models. Unsure what's in your box? Have an electrician look first.

How the comparison works

Your choices are compared with each model’s product details. A missing or conflicting value stays unknown and cannot satisfy a choice you select. The starting order helps you browse; it does not rate real-world performance.

Source dates appear with each link below. A source date does not confirm today's price or stock.

The neutral wire can decide which Leviton switch fits

Neutral-wire information covers 10 Leviton controls. The Decora Smart No-Neutral Dimmer and Wi-Fi Bridge Kit needs no neutral and includes a Wi-Fi bridge; the Motion-Sensing Dimmer needs a neutral and uses Wi-Fi. Compare the wiring before choosing the control's appearance.

These are Leviton's wiring and connection descriptions without an installation or load-control trial. Follow the exact switch's electrical instructions, and use a qualified installer when you cannot identify the wiring safely. A wireless connection does not remove the switch's wiring needs.

Network names do not describe what the switch controls

Leviton's Z-Wave Switch and Z-Wave Dimmer use the same connection type but different control types. The Wi-Fi range also includes a Scene Controller Switch and a Phase-Selectable Dimmer. Choose on/off, dimming or scene control to suit the actual load and intended function.

Connection information covers 10 devices, but the field is no inventory of required hubs or bridge accessories. Read the exact package contents and load-compatibility guidance; similarly shaped switches and dimmers are not interchangeable merely because they share a network.

Before you buy

Can any of these dimmers run the same lights?

No. The D2710 is built for 0-10V loads and the D2ELV is a phase-selectable dimmer (ELV / LED in Leviton's title), so they suit different fixtures; the load and installation notes on the exact model's page decide which one your lights need.

What comes in the no-neutral kit?

The DNKIT pairs a DN6HD dimmer with an MLWSB Wi-Fi bridge, so there are two pieces to place. Its page still sets wiring conditions of its own, and those apply before you pick it.

What sets the two Z-Wave switches apart?

Their titles name Z-Wave 800 Series where the others name Wi-Fi, and the connection filter keeps them apart: the ZW15S is an on/off switch and the ZW6HD a dimmer. What else a Z-Wave setup needs isn't covered here, so read the exact model's page before you buy. For plain on/off on Wi-Fi, the D315S is the switch.
