Sorry, that's wildly overstated. Many firewalls exist for the purpose
of *limiting*, not *preventing* traffic between systems, .e.g. creating
a DMZ for a corporate web or mail server (or server farm).

It would be possible to allow a tightly constrained inbound access,
but if the firewall owner is like most corporate IT types, getting that
approved would admittedly be tough.

So an alternate (very general) answer to the OP's problem would be
to proxy the device data out to the web server.
