Hi, I would like to make a device that I can connect to any TV and be able to turn the TV on/off from my house. These TV's I am talking about are in various places in the United States. Sometimes the school/center staff turns the TV's off. I need to be able to tell if the TV is off/on and be able to turn the TV on/off from my house without having to drive to every location. Please help me with my idea.
