Old Home - Existing 2 Wire Switches
« on: January 25, 2014, 12:33:39 pm »
I've searched and haven't found anything concrete on this (and understand there may be limitations here).  I purchased an older home last summer that was partially renovated electrically.  Many of the remodeled rooms were rewired, however there still exists a considerable amount of old wiring in play where in the switches have two wires.  My question is - with a pigtail, are there any options for Z-Wave switches or dimmers that are reliable with no ground?

I am considering redoing the remainder of the electrical with an electrician to expand the current box and remediate some capacity issues long term, but curious if there's anything I can use in the interim.  I had an older switch next to a newer one that I tried to leverage powering the switch with and still being able to switch the load, however that did not work as I expected.  And in all other cases in the house I don't have this option anyway.

Any help or insight is much appreciated!

The Leviton VRI06-1LZ works well for controlling incandescent and dimmable cfl / led bulbs. I'm in the same situation (no neutral in switch boxes), and I've been installing these where I want vera controlled switches.

If you have room in the boxes where your lights are actually installed, you can also use something like Aeotec/Aeon's micro switches.

Yes, you do have several choices.

Aeon Labs Micro In-Wall Appliance Switch As @cmdrake states, these can be mounted in the light's junction box, utilizing the neutral there and not requiring a neutral at the switch.

Leviton VRS05-1LZ 5A Incandescent Scene Capable Switch Note 5 Amp max.

Leviton VRI06-1LZ 600W Incandescent Scene Capable Dimmer LED bulbs may be an issue with this dimmer.

GE 45612 In-Wall Dimmer This dimmer does not work well with LED bulbs.

Thank you very much gentlemen!  Any oddities with no ground?  Buzzing, flickering, etc?  I've used GE dimmer switches in the past on the newer wiring and I found them to be pretty bad, however the Evolve switches I have don't exhibit any of that behavior.

Thanks again.  ;D

Update:
The funny thing is I was looking at the VRI06-1LZ on Amazon and forgot I accidentally ordered it with some other things.  Just reading through the install manual it looks like this should be a good fit.  Good thing I forgot to send it back!
