I bought a GE Z-wzve plus smart switch(
https://www.amazon.com/gp/product/B01M1AHC3R/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1). I have a house that was built in the 1890s. I am missing all the modern wiring. Is this switch useless to me now? Is there any way to get it to work? I would hate to break it to my wife we need a new house.
I think lutron switch doesn’t require neutral
Yes, unfortunately, that switch will not work for you.
There is one very good option that does not require a neutral wire and now has an official integration with Smartthings: the Lutron Caseta line. Most of their models do not require a neutral wire. You will however, have to get a Lutron SmartBridge (one SmartBridge can support about 40 individual switches) in order to make the integration work. But these are very well engineered switches, easy to install, and very quick. I use them in my own house.
There are a couple of other options you can look at, but the Lutron will be the simplest.
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).
(Lutron is an engineering company focused on lighting and holds a number of patents on their devices, which is why they can do what nobody else can for several features.)
