Also note that the requirement for an IP stack makes this far more complex than what you need for a USB interface. So while the hardware for the interface may be cheap, it places much higher demands on the microcontroller (and firmware) to actually use it. And I don't know what system this should be connected to, but by the time mine sends the UPS the command to shut-off the output (just before the killpower command), it no longer has networking capabilities anymore. So using an ethernet interface would require sending the shut-off command (with delay) well before the system has finished shutting down. This is a lot riskier than to do it after all services have been stopped and file systems remounted read only.
