Why you should trust this review
I purchased three Leviton Decora Smart Wi-Fi dimmers at retail in mid-September 2025 to install on three living-area light circuits. Leviton did not provide samples. Across 8 months the dimmers have controlled the main living room, dining room, and master bedroom lighting circuits with daily use including voice activation, app scheduling, and occasional Apple Home automations.
This review reflects Leviton’s published specifications, Amazon’s aggregate of 6,840 owner reviews (averaging 4.5 of 5), and 8 months of direct use across three switches.
How we tested the Leviton Decora Smart
See /methodology for the standardized smart switch evaluation protocol.
- Setup time: Tracked install time from box-open to working switch.
- Reliability: Logged disconnect events across 8 months.
- Voice control: Tested via Alexa, Google Assistant, Apple HomeKit, and SmartThings.
- Dimming smoothness: Checked on incandescent, LED, and CFL bulbs.
Who should buy the Leviton Decora Smart?
Buy this if:
- You want smart dimming without buying a hub or bridge.
- You have a neutral wire at your switch box.
- You appreciate native support for all major voice assistants.
- You only need a few smart switches, not a whole-house deployment.
Skip this if:
- You are deploying smart switches across the entire house. The Lutron Caseta with hub is more reliable.
- Your home lacks neutrals at switch boxes. Lutron Caseta is the no-neutral alternative.
- You want the cheapest possible smart switch. The Kasa KS230 saves $15.
Setup and reliability
Setup via the My Leviton app takes roughly 5 minutes per switch including Wi-Fi pairing. Across 8 months on three switches I have logged perhaps 6 disconnect events, all resolved within 30 seconds when the router stabilized. This is acceptable for non-critical lighting.
For users who switch the lights via voice or app dozens of times per day, the occasional disconnect is annoying. For users who mostly use the physical paddle and rely on smart features for occasional automation, the reliability is fine.
Voice control and value
Native support for all major voice platforms is the main advantage over cheaper alternatives. Alexa, Google Assistant, Apple HomeKit, and Samsung SmartThings all work without bridge devices. Apple HomeKit support specifically is uncommon at this price.
At $44 the Leviton Decora Smart is the right call for users who want smart dimming without committing to a hub-based ecosystem. The Lutron Caseta with hub is more reliable for whole-house deployment. The Kasa KS230 is the budget alternative. For most users wanting a few smart dimmers, the Leviton is the answer.

Should you buy the Leviton Decora Smart Wi-Fi Dimmer Switch DW6HD-1BZ?
The Leviton Decora Smart Wi-Fi dimmer is the right smart dimmer for users who do not want to add a bridge or hub. The 600-watt incandescent / 300-watt LED rating handles most rooms, the My Leviton app supports schedules and away-from-home control, and Alexa, Google, Apple HomeKit, and Samsung SmartThings all integrate cleanly. The trade is occasional Wi-Fi-disconnect events that hub-based systems like Lutron Caseta avoid.
Frequently asked questions
Is the Leviton Decora Smart worth $44 in 2026?+
Yes, especially for users who want smart dimming without adding a hub. The Wi-Fi connection is direct to your router, voice control works with all major platforms, and the 600W rating handles most rooms. If you have a hub-based system already (Lutron Caseta) the matching dimmer is more reliable.
Leviton Decora Smart vs Lutron Caseta: which should I get?+
Different priorities. The Leviton is no-hub-required and slightly cheaper. The Lutron is hub-required ($79 hub plus $64 dimmer) but has the most reliable connection in the smart-home category. For occasional smart use the Leviton. For demanding daily use across many switches, the Lutron Caseta is worth the hub investment.
Does it really work with Apple HomeKit?+
Yes, native HomeKit support. After adding the dimmer to the My Leviton app, you can also add it to the Apple Home app via the HomeKit setup code on the dimmer body. Siri voice control, Apple Home automation, and Apple Watch widget control all work.
Will it work with my older home?+
Only if your switch box has a neutral wire. Older homes without neutrals at the switch require rewiring or a hub-based dimmer like Lutron Caseta (which works without neutrals). Check your existing wiring before buying.
How is the dimming smoothness with LED bulbs?+
Smooth on most LED bulbs. The Leviton has a slight buzz with some cheap LED bulbs and a tendency to flicker at the very bottom of the dim range with budget LEDs. Quality LEDs from Cree, Philips, or Soraa dim cleanly across the full range.
