I have a gas fireplace running two low voltage wires to an electrical box nearby with a standard off-the-shelf light switch which shorts them together, closing the circuit and turning on the fireplace. So far so good.
But now I want control from Smart Things. I have nothing in that box except the two low voltage wires. No power. No neutral. Nothing.
So all I need is a battery-powered relay to close the circuit. For the life of me, I can’t find a suitable device.
I don’t have a lot of restrictions. The switch is already in a 2-gang low-voltage ring, and I have lots of space behind the wall. I would prefer Z wave, but it’s not essential. I would even be be willing to rig the batteries up myself if necessary if the solution takes something in the 3-12V DC range.
Can anyone offer a suitable battery-powered relay?
