Z-Wave Switch Integration for Gas Fireplace

I’m currently working on integrating a Z-Wave switch system for my gas fireplace, and I’m curious about the best approach to ensure seamless integration with my SmartThings setup. The fireplace operates on two switches, and I’m considering using GE Z-Wave switches. However, I’m unsure if I can simply install them without modifying the existing wallplate. Has anyone successfully integrated Z-Wave switches into a similar setup? I’d love to hear about your experiences or any potential challenges you encountered. Additionally, I’m exploring whether there are alternative solutions or configurations that might offer better compatibility or functionality. Any insights or recommendations would be greatly appreciated!
