I want something to remotely show the status of a light or outlet, i.e. whether the power is on or off. Why? I frequently leave the light on in my workshop or porch, and I would like to have an indication inside the house that the light is on or off. I envision a small radio transmitter plugged into a 120V outlet that would send an on/off signal to a remote receiver/indicator, presumably also powered by 120V, but other power sources could be acceptable. I would like it to transmit a signal 50 feet or so through a couple of stud walls. One that could transmit 200 feet through a couple of concrete walls would open up a number of further possibilities in my detached garage.

I have tried searching this forum and the internet without success. It may be that I don't even know what search terms to use. I would be willing to construct something from parts, although I would think such a simple device would be an available product; if not, maybe it should be. It would seem to have a lot of potential uses beyond my simple desire. I do not want to spend a lot of $$$ on this, although I might be willing to spend a bit more than it is worth just to see if I can make something practical. I am not interested in developing a commercial product. So, if anyone can point me in the proper search direction or give hints on how to make something like this, I would appreciate it.

All my workshop and garage lights plug into outlets mounted in the ceiling, so I could literally plug a transmitter into that. I could also tap into other light circuits pretty easily. I do not need remote control, only indication. I do not wish to put in long runs of wire or install expensive controllers just to get a lazy man's indicator. Suggestions like "just go look at it" are probably justified, but oddly ineffective.
