What makes a Home Smart? Let's go back in time. In 1975 the release of X10, a communication protocol for home automation, the smart home, once a pipe dream came to life. X10 sends 120 kHz radio frequency (RF) bursts of digital information onto a home's existing electric wiring to programmable outlets or switches. These signals convey commands to corresponding devices, controlling how and when the devices operates. Electrical wiring were not designed to operate free from radio-band noise, further, X10 provided unpredictable and unreliable signals.  Circuits were wired on different polarities and were created for 220-volt service. Additionally, X10 was initially a one-way technology, so while smart devices took commands, they could not send data back to a central network. Later, however, two-way X10 devices became available, at a higher cost. Most products are available in one of four protocols (the means of communication between themselves) and all of these are compatible with the internet, land phone, and cell phones. These are the names of the four: X10, Z-Wave, UPB and EnOcean. 

A "SMART HOME" is the term commonly used to define a residence that has appliances, lighting, heating, air conditioning, TVs, computers, entertainment audio & video systems, security, and camera systems that are capable of communicating with one another and can be controlled remotely by a time schedule, from any room in the home, as well as remotely from any location in the world by phone or internet. An emerging important feature of a smart home we realized at Green Capital is conservation of the earth's limited resources. More and more people are becoming aware of the ability to make their homes truly smart — and green — by utilizing energy efficient building materials and also home controllers integrated with all home sub-systems to increase savings by controlling lighting, window coverings, HVAC, irrigation and by monitoring usage. Many home controllers have built-in monitoring systems whereby they calculate and log usage by all connected devices, giving the home owner heightened awareness and the knowledge to make changes as necessary. These systems can even be accessed over the Internet from anywhere in the world so the homeowner can adjust consumption any time, anywhere. Machine learning and artificial intelligence (AI) are becoming increasingly popular in smart home systems, allowing home automation applications to adapt to their environments. For example, voice-activated systems, such as Amazon Echo or Google Home, contain virtual assistants that learn and personalize the smart home to the residents' preferences and patterns.
