Thankfully, they do exist.
And in the case that your home does not have neutral wires, hope is not lost!
Although you are limited to only a handful of smart switches that work in a 2-wire circuit and most are dimming devices.
A big caveat however.
Most of the available smart switches for no-neutral installs only work with incandescent or halogen lamps.
So make sure your shortlisted devices will work with the type of light bulbs you plan to use before you make your purchase.

Of course you can always bite the bullet and hire an electrical contractor to run neutral wires to each switch.
Just don’t forget to factor in the disruption (and mess) to walls and ceilings and making good at the end of the job.
And lets not forget you can always opt to go with smart bulbs like Lifx or Hue instead of switches.
One drawback is cost, depending on the size of your home and number of bulbs required.
The other drawback is a family member or guest could inadvertently turn off a switch rendering your smart bulbs useless.
And cutting power to smart bulb also seriously impacts their lifespan and should be avoided.
The other thing to be aware of is only people with access to the app are going to be able to control them.

They are generally installed directly behind the switch in the existing gang box.
As always check the fine print first, as you may need a bypass device added to make them work with certain lamps like LEDs.
It's also important to note that both the Aeotec & Fibaro devices communicate using the Z-Wave protocol.
This means you'll need a Z-Wave hub or controller, like Samsung SmartThings, to use these devices in your home.
The pick of the bunch that work with both LED and incandescent bulbs is undoubtedly the Lutron Caseta range.
While not the cheapest solution, they have arguably the most reliable and robust professional-grade smart lighting technology on the market here in the States.
Certainly for a vanilla installation project, where you are taking your first steps in upgrading from traditional dumb switches, Lutron gets our recommendation.
And their starter kits keep things affordable.
C by GE: Coming Soon In 2020
An exciting development announced at the start of the year for the C by GE range is a suite of smart switches and dimmers that don't require a neutral wire for install.
Manufactured in different 3 designs to match you existing home decor, the switches will be available as a toggle, paddle or button and the dimmer model will come in two flavors, a standard dimmer and a motion sensor dimmer switch.
With no hub required, these switches communicate with each other via bluetooth and connect directly to your home wifi for you to program and control the devices.
Amazon Alexa & Google Home work straight out of the box via wifi, with Apple HomeKit integration possible through an additional hub you can purchase separately.
To complete the new lineup, C by GE are also launching a range of complementary "controller" switches and sensors. These will be battery powered and require zero wiring, communicating with each other via the bluetooth network.
The switches are expected to start shipping in Q1, with the dimmers to follow shortly after in Q2 and we'll be publishing an article on the new range when they are released.
It's worth noting that the C by GE range is completely separate to the GE Enbrighten smart switches, which communicate using either Z-Wave or Zigbee protocols, are manufactured by Jasco and don't offer a no-neutral option at time of updating this article.
