* Network connectivity for the Pi is required but DOES WORK BEHIND A
FIREWALL. The only requirement is that the Pi must be able to connect
to the Internet.

Thanks again to those who already reached out!

"the Internet" - you mean Port 443, any IP?

Actually, no. We use a custom port to establish an gRPC connection from the Pi to our server back at ETH. So, if your network has tight security rules, the only thing we really need in one open port open towards one IP address.

Best,
