We’ve tested dozens of different types of 3 way smart dimmer switches to find the best 3 way smart light switch for you. We’ve narrowed down the top two choices that we use, and recommend based on our experience installing and using 3 way smart dimmer switches.
You can find 3 way light switches that work with wifi, z-wave or zigbee on the market. We typically recommend using wifi smart light switches when possible because they don’t require a smart home hub and will work with pretty much any wifi router and will allow for future compatibility with any smart home hub like Alexa or Google Home.
Top Pick - Best 3 Way Smart Light Switch: Leviton 1000W Wifi Smart Dimmer
I personally have a few of these in my home for 3 way switch locations at my stairwells. They have worked flawlessly for years without any issues and I have them connected to both Amazon Alexa and Google Home for voice control. These 3 way smart light switch dimmers connect to standard home wifi networks from your cell phone and don’t require any kind of smart home hub. The leviton app is simple to use and connecting the lights switches to the app is easy, just make sure you follow the instructions to put the light switches into pairing mode when trying to connect to the app. Once you have the smart light switch dimmers connected you can control them through the phone app at home or remotely with just a swipe of the app on your phone.
The 3 way smart light switch functionality requires that you purchase both the standard leviton dimming wifi light switch and a matching paired smart wifi dimming remote as they call it. The light switches were easy to wire up, without issue, they use a neutral, hot, load and traveler wire to work together. If the remote is not working most likely it’s possible that traveler wire and load wire were connected backwards, it’s typically an easy fix just take out the switch and switch the load and traveler wires.
It’s important to take a picture of the existing wiring before you pull of the old switch so you can identify the wiring for the new switch, it also doesn’t hurt to mark the wires so you know which goes where on the new switches.

Runner Up - Best 3 Way Smart Light Switch Dimmer:
The Lutron Caseta smart light switch dimming kit offers everything you need make your three way switch smart. The caseta smart light switch dimmers all connect to a central hub that can then control any other caseta smart light switches that you add to the system. The hub then connects to your router and can be controlled via wifi though the app for in home or remote control. The lutron caseta smart dimmers also work with both Amazon Alexa and Google Home.
The caseta smart light switch dimmers do offer two unique features not offered by many other smart light switches.
The caseta dimmers don’t require a neutral wire which can be very helpful if you are trying to rewire an older house which oftentimes don’t have neutral wires in the switch boxes. The caseta dimmers also work with caseta pico remotes which are actually battery powered but look the exact same as normal light switches. This means that you can turn any switch into a three way switch even without rewiring the switch because you can just mount the pico remote on the wall and connect it to the hub and it will enable three way switch functionality through programming in the hub.
If you already have a three way switch and want to use the caseta smart light switch dimmers you can just wire the circuit so that only one switch in the 3 way circuit is controlling the on/off function of the lights and on the other side of the circuit you will remove the old switch and cap or connect the wires as needed in the junction box and install the caseta pico remote where the old switch was and it will look identical to the fully wired smart light switch on the other side of the circuit.
