Have you ever heard about the idea of a smart home? Can anybody explain it to me? As I understand, it is a system of several devices with different technologies. For example, the door detects if you closed it or not and notifies you through an application to do it (or maybe does it by itself). I should also mention the opportunity to control your pets through the screen of your phone when you are out. By the way, I do the same with the Ajax app. So, is that all called a smart home or not?
