Here are the Z Wave Fireplace Switch pictures, I have replaced a fireplace switches with z wave and connected them. It would be easy enough to replace the switch with a z-wave. Z-Wave is the leading wireless home control technology in the market today, with over 2100 certified interoperable products worldwide. Also I have a gas fireplace that has a single 2 conductor wire coming from the fireplace to a toggle switch on the wall that turns on-off the fireplace.
