Leviton Decora Smart Switch uses the Wi-Fi protocol and can power up an LED/Fluorescent bulb up to 600W, or an Incandescent bulb up to 1800W. It doesn’t come with the dimming feature so it can only be used to toggle on/off certain lights.

Using the native app or your supported home hub, you can schedule lights to operate. Some flexible features are sunrise/sunset timers, custom light scenes, and automatic turn-off. It also comes with a vacation/randomization security feature which makes lights go on and off randomly creating the impression that somebody is at home.

The design of the switch is modern and a variety of color change kits are available if you want to match it with your current interior.

Leviton Decora Smart Dimmer comes with the dimming capability and includes all features that Leviton’s normal smart switch has. It looks aesthetically better for its brightness rocker and LED brightness indicator bar.

This dimmer has two different variants in terms of supported load. One of them supports up to 300W of LED/Fluorescent and 600W of Incandescent load. Where the other supports up to 450W of LED/Fluorescent and 1000W of Incandescent load. You can choose depending on your current configuration.

Other features are pretty identical such as smart scheduling, time-based auto turn-off, vacation mode, and the availability of color change kits.

Leviton Decora Voice Dimmer has all the features of a Leviton switch and dimmer, plus it houses an Alexa module on the inside. Meaning that you can ask the switch directly to do something for you.

What’s interesting is that this Alexa can also be used to do other typical home assistant chores. It has a microphone and a loudspeaker built-in. So if you wish, you can make it play a song for you like any regular smart speaker.

If there is any downside, I would say it is the max load capacity. Where other switches able to handle up to 1000W, this voice dimmer can do only 300W regardless of the bulb type.

Leviton Decora Fan Speed Controller brings the same smart light switch experience to fans and adds the ability to control the fan speed via voice commands and preset schedules.

All other smart features remain the same such as schedules, sunrise/sunset timers, auto shut-off, and vacation mode. The speed indicator LED and the dedicated speed changing button only increases the practically of this switch.

In case, if you have fan lights, this device does not have controls for them by default. You will have to buy a separate Leviton dimmer and pair them together to make this work.

Leviton Decora Plug-in Dimmer is simply the same smart switch but in the form of an outlet. That means, no wiring is required. Plug this in any regular wall outlet first, and then plug your lamp or any other kind of light onto it.

Feature-wise, it is identical. You can turn on/off, dim lights, set schedules, control it via voice assistants, or set shutdown timers. The major noticeable difference is at the supported load. It can power lights up to 300W.

Decora Smart with HomeKit Technology

The regular Decora Smart variant does not support HomeKit. However, they have the exact same switch and dimmer made for HomeKit. If you have a HomeKit-based system, make sure you are picking this one, not the one for Amazon Alexa.

Currently, the 15A regular switch and 600W/1000W dimmer switch are only available for the HomeKit platform. It is unknown if the company wishes to release the plug-in dimmer or the fan speed controller for HomeKit.

One thing which is technically a drawback is that Leviton devices are not cross-platform compatible. The HomeKit version will not work with Amazon Alexa and also not the other way around.

Leviton Decora Smart Dimmer with Z-Wave Technology

Similar to HomeKit, Decora Smart also has a product lineup featuring Z-Wave technology. Feature and design-wise, they are all identical. Only the used wireless technology is different.

Nearly all their products have a Z-Wave variant that includes the switch, dimmer, fan speed controller, and plug-in dimmer. Again as a reminder, none of these devices are cross-platform compatible.

There are so many smart switch companies out there that it is fairly difficult to choose one. The biggest advantage Leviton has over the other switches is that it is not dependent on hub/bridge. You don’t need any hub to use it to its fullest.

One other benefit of Leviton is that it supports nearly all wireless protocols. In this post, we covered Wi-Fi, HomeKit, and Z-Wave products, but if none of them matches your current configuration, you still have to option to pick some of their Bluetooth products.

Besides that, Decora Smart devices are covered by a massive 5-year limited warranty. Prolonged warranties are not easy on electrical products but they were brave enough to offer this to their customers.
