I have some cheap remote control devices, like GE Smart Remote, but I want to detect activity with the Elk. To state the problem in a simple way: How could I detect a simple 120v circuit's state (open or closed) easily and cheaply? Would you just use a relay to close a low voltage (Elk) input?

Using a 120v relay will give the most flexible option. Plus, it also gives you electrical isolation between the high and low voltage device wiring.
If you are looking for power failure status without false alarms use something like this:

It has a heated element (resistor) and a thermal switch inside to create a delay.

I detect if my TV is on or off using a trickle saver. The "other device" is an old 12V AC wallwart connected to an X10 PowerFlash module.
