Need light switches that works with no neutral line

[Rockrabbit (Isaac Katzav)]

Hi,

I have a 4 way installation and a 3 way installation that doesn’t have neutral lines. Can someone recommend a light switch (primary and slave) that supports SmartThings and doesn’t require Neutral.

I use GE ZWave elsewhere in the house and work great but can’t use it where I don’t have neutral as they have to have them in order to work.

Lutron is not a solution since it appears not working with smart things.

Thanks,
IK

This is a common question in the forums. I know it can feel really frustrating, since most of the available switches do require a neutral to power the radio. There are some zwave options, but it’s important to note that all of the dimmers that don’t require a neutral are only rated to work with incandescent bulbs, not LEDs.

Lutron use a proprietary patented method that does work well with most LEDs and doesn’t require a neutral, but as you noted there’s no direct integration with SmartThings. You can get indirect Lutron integration using IFTTT. However, this method introduces some lag, and the amount of lag varies from person to person. At my house it’s about eight seconds. That’s fine for lights that are on a time schedule, but would typically be too long for lights that were triggered by a motion sensor.

All of these have matching auxiliary switches that can be used in three or four way set ups.

The following thread discusses the specific options:

Dimmers/Switches that don't need a common (neutral) wire? (2016)

I’m having a terrible time trying to get a three-way switch automated. While the rest of my switches in the house all have a common wire (and are easy to install the GE Z-Wave Dimmer) our Kitchen overhead recessed lights have the simple tap side “cheaped out” with no common wire available. Having an electrician run such a wire through our attic will be $$$$. When I started with Insteon most of their stuff required a common wire but for situations in older homes or where the wiring was expedient (like this situation) they offered an RF Dimmer Switch that didn’t require it. I don’t suppose there’s anything anyone makes for SmartThings type Hubs that could also work without a common wire? It irks the hell out of me since this is a light I really need to automate (and be able to dim).
