Controling relays over phone line
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.
