Smart homes have been in the works for years. Recently, more established tech organizations have been putting out newer and more highly advanced smart home products. But before that, a company in Scotland developed the x10. All of the products are receivers and they make up the controlling of the system. An example of this is turning off a lamp that’s in a different room. The appliance being used sends an alert that is transferring the command, it identifies the unit number for the device that should receive the command, and it scans the numerical code that correlates with the command. In this case it is to turn off the lamp. Although the x10 had many families intrigued, other companies have competed to have more efficient products and more customers. Instead of going through the power lines like the x10, many updated systems use radio waves to communicate (which is how Bluetooth and WiFi signals work). With companies exceeding previously held technological limitations, homes all over the world will soon have these new advancements and will continue to grow alongside technology.
