I found a microcontroller with ethernet, tcp/ip embedded into the silicon. $4 There is a rabbit for about $30 that will do similar things.
I want this thing to be $20 and as small as a jump drive. From: D.

When the relay is open, the connection goes away. I am looking for a way to do some centralized polling of ports like that. I don’t want to have to build some kind of small ardueno board and burn an IP for each one. But I can’t think of a way around using an IP unless the device, such as a managed switch can do an snmp trap for each port. Maybe it will become a product if it doesn’t exist. Telemetry on a stick. Two terminals for a contact closure. POE powering. Pollable and trap sending. Hopefully something like this already exists? -- D.
