What are the best smart light switches that don’t require a neutral wire

Smart light switches without a neutral wire are rare, but there are several brands catering to your needs. Lutron Caseta is a personal favorite, though it requires a second bridge or hub to get them “active” on your smart home network. A GE Cync switch works without a neutral wire or hub, making it the most affordable option.

Smart switches never sleep

Many homes were wired before the National Electric Code required every light switch junction box have a neutral wire. If you own such a home, many of the best smart switches won’t work for you. Every smart switch needs a neutral wire attached because they need to stay powered all the time.

Without a neutral wire, there is a single circuit between the bulb, power source (or junction box), and light switch. If you switch off the lights, the electric current is broken because no power is passing through the bulb. That’s why you typically need a neutral wire, which directly connects the power source to the switch: If you turn off the lights, the circuit still breaks, but the neutral wire gives the switch its own persistent source of power.

There’s a reason why almost every smart switch needs a neutral wire attached.

If your house doesn’t have neutral wires, your options are to rewire your home to add neutral wires, buy and add microcontrollers inside the switches to smarten them up or buy smart light switches that work without a neutral wire or microcontroller. We recommend you consult with an electrician before pulling out switches or starting any rewiring in your home. There’s always the potential to get hurt, so be safe instead of sorry.

The easiest option is to simply buy compatible smart switches, but keep in mind that most of them only work by connecting through a compatible bridge or hub, which stores programming data like your wireless network details and login. These hubs won’t cost as much as an electrician, but they’re still fairly costly.RECOMMENDED VIDEOS FOR YOU…Google Pixel 6 + 6 Pro Full Review: A new era for Pixels!https://imasdk.googleapis.com/js/core/bridge3.516.0_en.html#goog_13676950340 seconds of 21 minutes, 49 secondsVolume 0% PLAY SOUND

Lutron’s smart switches and hub cost more but are compatible with more smart home tech. C by GE offers a more independent smart option.

Our favorite smart light switch without a neutral wire is the Lutron Caseta Smart Lighting Dimmer Switch. It works with Amazon Alexa and Google Assistant, has a handy app, and works with almost any light fixture you have in your home. Plus its Wireless Smart Bridge hub connects with things like powered window blinds, ceiling fan controllers, wireless “pico” switches that you carry around, and even motion sensors. With up to 75 devices controlled by the Smart Bridge, if you plan to use any other Lutron equipment, the extra cost is worth it because you won’t need another bridge.

Unfortunately, this all adds up to an expensive purchase. If you want something a bit more affordable and don’t need a dimmer switch, look into the GE Cync Smart Light Switch. It also works with Alexa and Assistant (or mobile app) without a neutral wire or a hub. It requires an adapter to work with certain light bulbs, but it’s included in the box. It’s the only truly affordable option available without a neutral wire, without worrying about an entire smart home family to go with it.

If you’re specifically looking for a HomeKit-compatible option, look into the Aqara Smart Light Switch, which works with all three smart home systems. It also gives you single or double rocker options, in case you want to control more than one switch. You’ll have to buy the Aqara hub as well, but both the switch and the hub are more affordable than Lutron’s, giving you a good middle option.

Otherwise, if you decide that smart switches and hubs aren’t worth the hassle, keep in mind that most smart bulbs don’t require a hub, and they’re fully compatible with any power outlet regardless of the neutral wire.

The best alternative for your neutral wire-less smart home is to check out the best smart bulbs or the best Alexa-controlled light bulbs instead. They’re generally more expensive per bulb, but they save money by not requiring a hub, and they also offer app controls and Alexa voice commands.
