Hi all,

I am looking to 'smartify' my gas fireplace, which I currently control with a wall switch connected to the low voltage circuit of the fireplace (voltage generated by a thermopile, haven't measured it but from what I've read its normally 300-700mV DC):





The easiest way I see to do this would be to buy a smart lightswitch (Lutron, as it will integrate into my existing system), then use a relay to control the low voltage circuit, so it would look something like this:






In theory I don't see why this wouldn't work, I am just not sure how to select the right relay. From what I understand something like this would work:

I just want to see if other people have done something similar? Even if not, just looking for input on this project.

If not that relay then maybe something else on this list? https://www.digikey.ca/products/en/relays/solid-state-relays/183?FV=a40155,1fc006b,1fc0505,1fc0511,1fc1216,1fc0037,1fc192d,1fc1e65,20800ed,ffe000b7&quantity=&ColumnSort=1000011&page=1&pageSize=25

First time relay buyer as you can tell... :S

Thanks in advance for your help!

Electrically your solution is fine. Your issue will be to mount the relay in a code compliant manner that keeps the 120 VAC and the very low voltage separated.

Hm I hadn't thought of that--I was planning on putting the relay in a large junction box in the ceiling that is accessible through a panel (to control an HVAC damper). I didn't think there would be a requirement to isolate them from one another aside from making sure they are secure etc like normal within the junction box...
