Is it possible to look at the live data remotely instead of having to use the local connection?
yep, you need to put some rules on your router to say
if someone outside connects to port number pppp on the router from the internet - take the connection through to internal IP-address (whatever your pi is) port nnnn
if your ISP randomly changes the external IP address of your router then you need a dynamic DNS entry that follws your router around ( see noip.com/free )
Thanks
Or use ngrok service it’s secure with https and you don’t need any dynamic dns service
