A:AnswerIt will replace any electric switch. This switch is really a timer that links to your electric outlet via wifi. It's no different than your existing switch. Electric part of it same as your existing switch which consist of red, white, black, green wires. The only difference that this switch differs from regular switch is the WiFi connection that serves as a manual clock timer, only through WiFi connection, whereas the manual timer has to be connected to an electric outlet and set the time to desired timeframe to switch the circuitry on/off at desired time. That's all. But as a convenience, it serves in a giant way. It does everything on its own at desired set time. Manufacturers are shy from extensive details, because they tend to make it seem as if it's something of a more complex and complete piece of science rather than a timer switch. Whichever you wish to interpret it, it's all for your good sake. Do you mind? Thanks
