@Narya so. your home network can’t be seen for outside your home unless you do some extra work configure your router to allow incoming requests(off by default) so, let’s say u want users outside your house to use a url like http://fribble.home.someplace.com:8023 then your router has to pass that request only the machine on your network running MagicMirror on port 8080 this is called port forwarding now the next challenge is to locate your router on the internet, as connected by your isp. by default the isps give out addresses via DHCP , and do not register a name for each home/router. you can find the address using the https://www.hashemian.com/whoami/ url on your machine running MagicMirror you can use the ip in your qr, http:ip_address:8023 now. ‘most’ of the time your router will retain one IP address. but it CAN abd DOES change there are services that can map a fixed name to an isp IP address. I use dyndns.org, and my router keeps the setting up to date. ( a Google search will find other ddns services) then your qr code would use the fixed name and port used in the port mapping. now, SOME isps don’t allow incoming requests on normal accounts. I’ve had two over the last 20 years that required a special static address account ( for more money) where would u post your qr for them to use from their phone?
