All the things you need to know about Smart Home and Z-Wave

DEFINING THE TERM – “SMART HOME”

A Smart Home is a dwelling that provides its home owners comfort, security, energy efficiency (low operating costs) and convenience with a simple click of a button or may also be a combination of. It makes human lives easier and even helps people with disabilities live as fully as they can.

“Smart Home” is the term used to define a residence or a dwelling area that has appliances, devices, 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.

BENEFITS OF HAVING A SMART HOME

Installation of smart products give the home and its occupants various benefits — the same benefits that technology and personal computing have brought to us over the past 30 years — convenience and savings of time, money and energy.

Most homes do not have these appliances and systems built into them, therefore the most common and affordable approach is for the homeowner to retrofit smart products into their own finished home.

Most products are available in one of four protocols (the means of communication between themselves) and all of these are compatible with the internet, phone, and cell phones. These are the names for the four: X10, Z-Wave, UPB and EnOcean. Products that use the same protocol offer the ability to add products and hardware at the homeowners own pace and budget. An emerging important feature of a smart home 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 home controllers integrated with all home sub-systems to increase savings by controlling lighting, window coverings, HVAC, irrigation and by monitoring usage. These systems can even be accessed over the Internet from anywhere in the world so the homeowner can adjust consumption any time, anywhere.
