Description

Z-Wave is the leading international standard for wireless communication in Smart Homes. Different products from different vendors work together and interoperate in one single network to provide intelligent lighting, safety, security and energy efficiency. This book describes all you need to know about Z-Wave: The radio layer standardized by the international ITU organization, the networking between the device to realize a stable communication and finally the device specific application functions that ensure the interoperability between the different devices. Practical guidance for the installation and trouble shooting of wireless networks is provided as well.

1 Introduction
Z-Wave is an international standard of wireless communications for home automation. It interconnects different devices such as lighting, heating, climate control, media and entertainment, safety equipment, and security systems. The interconnection of multiple systems creates a smart home where devices from different vendors work together, thereby enhancing safety, security, convenience, and the quality of life of the people living in that environment. More importantly, a smart home helps to save energy and to protect human life and the environment.
The key to smart home automation is the interconnection of various devices and the ability to control all of them through a single user interface, which may be a web browser, a wall touch panel, a dedicated remote control, or a mobile phone.
The interconnection of devices in a residential home requires common communication media. There are three different approaches to this:
Wired solutions require dedicated cables to be installed during construction or major house renovation. Wired solutions such as BACNet (a protocol that runs on different media types), and certain versions of LON or KNX, namely Instabus in Europe, are generally expensive and therefore used in commercial installations and very high-end residential homes.
Powerline communication uses 110 V or 230 V mains power installation as communication media. Certain standards such as HomeplugAV are more common, but they are mainly used as a replacement for Ethernet technology applied for media distributions such as TV, video, and audio.
Wireless solutions show the biggest growth in the market since they are both reliable and affordable and can be applied in homes without major refurbishments. Additionally, certain technologies such as intelligent door locks or sensors can hardly be installed with wires because they are used on moving devices such as doors.
Therefore, wireless technologies can be considered the future basis for interconnecting devices in a smart home.
1.1 What is a Smart Home?
Smart home is a term often used along with the more descriptive term home automation. Wikipedia defines home automation as:
Home automation is the residential extension of building automation. It is automation of the home, housework or household activity. Home automation may include centralized control of lighting, HVAC (heating, ventilation and air conditioning), appliances, and other systems, to provide improved convenience, comfort, energy efficiency and security. Home automation for the elderly and disabled ca
