Thanks for the video! I found the SWI wires under my fireplace, which appear to be the same gauge as your wiring in your video but they are connected (with a wire-nut) to much thicker wiring. Is this a concern? I confirmed they are the correct wires as with one of them unplugged the wall switch no longer works, but I don't see yours connecting to thicker wiring, unless it's off camera. Thanks for any help you can offer!
The problem I see with the way you wired this is that there's no way to defeat or override what the smart switch does. Rather than wiring it in parallel with the manual switches it should be connected in series with one of the switches (preferably the wall switch if you have one). In that way you can simply turn off the wall switch to keep Alexa or Google from accidentally opening the gas valve when you don't want it to. Always think about fire safety when working on any electrical control project (especially when it happens to be a fireplace LOL)...
Do you have a link to the fully made one on Amazon and smart switch? I can’t solder

That's not a concern, you can just use the existing wire nuts instead of the metal clips
