Fireplace Dry Contact + Two Switches?

I’m wondering if this would work.

I am moving most of my switches chest to Lutron Caseta. Hopefully this could work with it but even if their Select bridge is needed I could go that route as well but hoping to stick with Caseta.

Not sure just yet how this device will work. Trying to picture is in my head as I write this.
