Leviton Decora Smart Dimmer Switch, Wi-Fi, Works with Matter, My Leviton, Alexa, Google Assistant, Apple Home/Siri & Wired or Wire-Free 3-Way, Neutral Wire Required, D36HD-1RW, White
Quick take
This hub-free Wi-Fi smart dimmer lets you control brightness remotely in the My Leviton app, and it also supports Matter for local smart-home integration with platforms like Alexa, Google Assistant, and Apple Home (Siri). It’s designed for smooth dimming with compatible bulbs and includes options like fade rates and preset light levels. The biggest buying caveat is wiring: neutral wire is required, and 3-way use depends on pairing with the right companion (wire-free companions or a wired companion).
Pros and cons

What buyers think
Buyer-review evidence for this dimmer highlights a few recurring themes. Setup and pairing are described as straightforward, with users reporting successful integration with voice assistants and smart-home platforms. Reliability and smooth operation show up frequently, including comments that the dimming experience is steady (for example, no noticeable flicker when paired with appropriate bulbs). There is also clear positive sentiment around Matter and Apple Home compatibility, suggesting buyers value local integration as smart-home ecosystems evolve. Overall, review evidence supports the idea that this is a practical “install and use” smart dimmer when wiring requirements are met.
What this smart dimmer does, in plain terms
The Leviton Decora Smart Dimmer is a wall switch dimmer designed to bring smart control to dimmable lighting. Instead of relying on a hub, it connects directly to your 2.4 GHz Wi-Fi network and gives you control through the My Leviton app. You can also use voice assistants to adjust lights or manage on and off states.
On top of basic dimming, it includes personalization features such as fade rates (gradual transitions when turning on or off) and preset light level options so lights can come back at your preferred brightness. There are also night-oriented behavior options intended to soften lighting in evening use cases.
Compatibility and connectivity: Matter, Wi-Fi, and voice control
This dimmer supports Matter and uses your Wi-Fi for control, which means it can fit into modern smart-home setups. It is designed to work with major ecosystems, including Alexa, Google Assistant, and Apple Home (Siri), so you are not locked into one platform. For buyers focused on local control, Matter support is a meaningful differentiator compared to smart dimmers that only operate through cloud connections.
Dimming performance and flicker-free considerations
The dimmer is designed for smooth, reliable dimming, including flicker-free operation when used with dimmable LED bulbs and compatible fixtures. It includes adjustable settings for bulb type, minimum dim level, and maximum brightness, which can help you fine-tune behavior for the specific bulbs you have installed. If you have ever experienced unstable brightness, frequent flicker, or “weird” dimming ranges, this kind of configuration is exactly what you should look for in a dimmer.
3-way switching options (wired and wire-free)
If you need control from two locations, this dimmer supports both approaches:
- Wire-free 3-way expansion: you pair it with compatible DAWDC Anywhere Dimmer Companions or DAWSC Anywhere Switch Companions, reducing the need for extra wiring at the second location.
- Wired 3-way expansion: it can work with a wired 3-way companion (a DD00R wired dimmer companion is referenced for hard-wired 3-way use).
Before you buy, confirm which style matches your home. Wire-free is often simpler when you cannot easily add wiring, but wired solutions can be preferable when you already have the right wiring present.
Neutral wire requirement: the main thing to verify
This smart dimmer requires a neutral wire. That requirement is non-negotiable for many smart dimmers, but it becomes especially important in older homes or retrofit situations. If your switch box does not have a neutral conductor, you may need an alternate approach or an electrician-assisted solution.
Who should buy it
- You want a hub-free smart dimmer that connects directly to your 2.4 GHz Wi-Fi network
- You are building or upgrading a Matter-enabled smart home and want lighting to integrate cleanly
- You prefer voice control across Alexa, Google Assistant, or Apple Home (Siri)
- You want smoother lighting transitions, with adjustable fade rates and preset brightness levels
- You need a 3-way smart dimming solution and can use wire-free companions or a wired companion
Who should avoid it
- You cannot provide a neutral wire in the switch location
- You are unsure about your 3-way wiring plan and do not want to research companion pairing (wire-free vs wired)
- You need a dimmer for non-dimmable bulbs, since this model is meant for dimmable loads
Bottom line verdict
The Leviton Decora Smart Dimmer is a strong fit for buyers who want a clean, modern smart dimming upgrade with Matter support, no hub requirement, and practical features like fade rates and preset brightness. It is also a good option if you value compatibility across Alexa, Google Assistant, and Apple Home. The tradeoff is that success depends on correct wiring, especially neutral wire availability, and getting the right companion setup for 3-way control.
