I have a fireplace that uses a 12v switch to turn it on/off. It?s not a regular 120v switch with a neutral or ground, it?s a two cable 12v using a regular home on/off switch. There is no neutral or ground, just a two cable 12v switch that turns on the fireplace on and off. The switch uses a regular home on/off switch to create a circuit between the two cables. Since most z-wave switch are 120v and also most needs the Neutral, what can I get to get a z-wave switch switch to turn on the fireplace on/off?
The Fibaro FGS221 and FGS222 recommended above could definitely be used in combination with a standard external wall switch to do what you want. But, I have yet to see these devices available in the U.S. You don’t say where in the world you are, but the absence of references to 240volt causes me to assume U.S. so…
What you need is a dry contact or isolated type relay. It will be powered by 120VAC to run the Z-Wave radio and relay electronics, but the relay side will supply no power, so it can switch your 12V AC or DC circuit. This means that you’ll need to run a 120VAC wire to whatever Z-Wave device you might choose.
The Remotec ZFM-80 could be used and offers a push button switch to activate/deactivate it. But, they don’t look the same as a regular switch and availability could be an issue.
I have a fireplace that gets turn on and off by a regular light on/off switch, but the switch just makes a circuit in a 12v line to initiate the on off of the fireplace.
All zwave switches I know off carry a 120v and needs to connect to the neutral. Is there such a switch that would turn on and off a 12v circuit?

There are several ways to do this, but your also going to need 120v just to power the z-wave device. You can’t have only a single wire 12v in and expect that to power a zwave device.
It has 120v hot and neutral in to power the switch (L and N) but it has another dry contact 2 center posts (which are E) and that would connect to the 2 12v wires you have going to your current switch. The other 2 wires are only used if you wanted a remote switch mounted somewhere else like a 3 way switch.
Like I said the problem your going to have is you probley only have a box with 2 wires (12v coming in and a wire for 12v going out) you will not find anything that is going to work with one 12v input wire (doesn’t even have ground just power). So if oyu have a switch near by that you can fish/share power off of that’s going to be your best bet.
Maybe post some pictures of the switch location and other switches around it if you don;t know of a solution already.

Use a zwave thermostat as your switch? You can get a battery operated version from Radiothermostat. It works well for me. The location is on an outer wall near a window, which is awful for a thermostat, but as a switch, it is great. If you buy good batteries you should get 4-6 months between changes.

If I asked again do you think one of you can give me the answer I want?[/quote]
Yes; just start a new thread with the exact same title in a different forum on this site.
On the relay device: I have one interfaced with a garage door opener / garage door opener remote; but yes, need 120V, and no physical switch. The older Fibaro’s could be run off of 24V; have that in use for operating a pool deck (in Europe).
Not aware of another low-voltage device, other than the suggested thermostat workaround.
If you could find a “Z Wave” relay that has both a Normally Open and Normally Closed pin (plus common, of course), you could replace your wall switch with a three-way switch and then use a three-way circuit.
My fireplace is a millivolt valve type and already has two leads coming off of the mechanical toggle switch for connecting a remote. I can just touch the two leads together and the fire starts (millivolt circuit).
There is also a 120V outlet inside the fireplace that is switched from a regular light switch to the right of the fireplace. A fan in the back of the fireplace is plugged into this.
I plan to hookup the LFM-20 to the millivolt leads and use the 120V switched outlet to power it. I will use a Aeon Labs DSC06106-ZWUS - Z-Wave Smart Energy Switch to control the fan. I will just leave the switch on all the time. All this is inside the fire place under the flame area.
I do not know if your fireplace is similar to this or not, but it is a common scenario.

The two wires that you have laying around are usually hooked to a on/off switch on the wall and the power is constant on and hooked directly to the fireplace unit. The switch on the wall does just what you say touches the two wires together and completes the circuit starting the fireplace.
You setup seems to be different the OP and most house installs. as they didn’t put your start switch outside of the fire area, maybe only had a wireless remote? What was the normal way you light the fire by touching the to wires in the fireplace or remote?
[quote=“integlikewhoa, post:15, topic:190677”]What was the normal way you light the fire by touching the to wires in the fireplace or remote?[/quote]Couldn’t resist. Sorry.
Just wanted to say that, given the reliability issues I and and others on this forum have had with the MIMOLite, I would be VERY hesitant to use this for a fireplace. Granted my issues have mainly been with the sensor, but you want any solution regulating fire to be rock solid, IMO.
