It might be “yet another” «device» controller that operates over phone-line, but this one works for sure :) The task was to build a device that connects to the phone line and has a relay as an output switch. It should also sense if the connected «consumer» is turned-on or off and report to the administrator at the other end of the phone line. The administrator would then call-in the device, log in with the password, and check the state of «consumer», turn it on or off, change password or some other settings. Current version has only one relay.

Does anybody know of something similar that works over ethernet?
Ethernet is more complicated than a telephone line. Each device need an IP address to be controlable and it has to support some kind of protocol such as TCP/IP or something else over TCP. However Ethernet device is much more powerful than an phoneline device.
