Best Smart Light Switches That Don’t Require A Neutral Wire in 2019

Best answer: There are a lot of homes that were wired before the National Electric Code required every light switch junction box have a neutral wire. If you live in one, you’ll be faced with some obstacles should you decide to install smart switches in your wall. The good news is that there are smart switches you can use that don’t need a neutral wire. The bad news is that they all require the purchase of a second bridge or hub to get them “active” on your smart home network.

Smart switches never sleep

There’s a reason why almost every smart switch needs a neutral wire attached: it needs to stay powered all the time.

That’s what a neutral wire does (in this case); it allows the circuit to be completed and the switch to be powered when you have turned it to the off position to turn off a light. Without one, the circuit is broken when the switch is in the off position and powered when the switch is in the on position. This is because the neutral wire for the circuit is actually in the junction box that holds the light fixture, and the two wires coming down to the switch are the “hot” leg that will power the light.

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

Smart switches that work without a neutral wire need to connect through a bridge or hub because of the programming — things like your wireless network details and login — are stored in the hub and not a microcontroller inside the switch. Now is also a good time to recommend that you talk to an electrician before you start pulling out switches or doing anything with the wiring in your home. There’s the potential to get hurt, so be safe instead of sorry.

The best switch to use if you don’t have a neutral wire depends on what else you might want to make “smart” in your home. Lutron’s Caseta system is more expensive, but the hub also works for things like powered window blinds, ceiling fan controllers, wireless “pico” switches that you carry around and even motion sensors. If you plan to use any other Lutron equipment, the extra cost is worth it because you won’t need another bridge.

If you only want smart switches, or you already have the rest of your house wired up, you can save a bit of money by going with the Insteon system. The bridge is $40 cheaper, and you’ll save money on every switch you buy. It all adds up!

Both choices work with Amazon Alexa, have smartphone apps, and will work with almost any light fixture you have in your home. The biggest difference is the price.
