Interesting.
I would like to monitor environmental features (temperature, wetness, etc.)
remotely, in a commercial building that I own. Let's say there is an
always-on DSL internet resource in the building. There is one static IP
address associated with the internet subscriber's DSL modem. A firewall
router follows next, and links LAN computers to the internet. That firewall
normally blocks outside folks (like me) that might try to access a wetness
sensor attached to the LAN.

There is generally one port on the router that can be configured to operate
without firewall protection. I could put my sensor on that ("DMZ" i.e.,
DeMilitarized Zone) port.

How does your weather station connect to the internet?
