GE Cync 3-Wire Smart Switch Review

Most smart switches require a neutral (white) wire to maintain the Wi-Fi connection, but if your home was built before 1985 (or thereabouts), this may not be an option. If you fall into the latter category, the Cync 3-Wire Smart Switch ($44.99) is worth a look because it gets rid of that prerequisite. Instead, it uses internal circuits, load current, line, and ground wires to ensure stable Wi-Fi access. We like that the switch responds to both Alexa and Google Assistant voice commands, but we’re disappointed that you can’t use it with ceiling fans or other third-party devices via IFTTT. The Wyze key It is a better choice if you need support for others smart home platforms, but the Cync Smart Switch is worth checking out if you own an older home because it circumvents the need to rewire your junction box.

Only works with lighting fixtures

With a white finish and a simple switch, the Cync Smart Switch is very similar to a traditional light switch. Below the cover panel there is a reset button and a small LED that flashes blue during setup and lights up red if a connection problem occurs. In the back are two black wires that connect to your home’s load and line wire, along with a green wire that connects to your home’s ground wire.

Also note that GE recommends this switch for lights only and not for ceiling fans or anything else.

The adapter uses the same mobile app (available for Android and iOS) as other Cync devices. It appears in a dedicated panel on the home screen with any other devices from the company you’re using.

The Cync switch did not cause me any problems during setup, but if you are not comfortable working with high voltage electricity, you should hire a professional. You can use the written guide to complete the installation or follow the video instructions in the app (which you need to download anyway).

First I turned off the breaker that supplies power to the switch I wanted to replace and removed the old hardware. In addition to naming the wiring, I also recommend taking a picture of the wiring for future reference before continuing.

Next, I connected the home load and line wires to the black wires on the Cync switch and then connected the house’s copper ground wire to the green wire. I secured all three using the included wire nuts. I poked the wires into the junction box, secured the switch to the box, attached the mounting plate and cover, and put the power back into the circuit. The LED has started blinking blue at this point.

Simple smart light switch

If wiring in your old home prevents you from outfitting it with smart light switches, the GE Cync 3-Wire Smart Switch offers a solution. It is ideal for homes built prior to the mid-1980s because it does not require neutral wires or a hub. Instead, the switch relies on the Wi-Fi radio to connect directly to your network, in addition to enabling audio and app controls. However, if your home has neutral wires, you can save some money with Wyze Switch, which supports much larger third-party integrations.
