It is expensive but that Frient keypad is what I have and it’s fantastic. Been running it for about a year now and it’s rock solid. I’ve even repurposed Nest tags to work with it.

I’ll let folks with more security experience dive into your specific question, but another option is to host your website on something like Github pages (using a static website generator like Jekyll) and point Cloudflare at it. That way you don’t need anything pointed at your local network, get the uptime of Github, and still benefit from your own domain name.

That’s what I’m doing with my own blog and it’s been great. Github provides the service for free but if they ever charge for it I’ll just start hosting it locally.
