In recent years the radio frequency is the technology most widely used for the transmission of signals in the field of home automation since it provides a convenient and economic solution for the realization of a home network or in small offices. The system that we propose is based on the software HomeSeer which constitutes by means of a hardware controller or a simple pc the processing center of the system.
The data transmission protocol between the central unit and the sensors, use more, is Z-Wave but the system requires compatibility with other protocols such as Isteon, X10, UPB and PCL-BUS. This protocol is optimized to be reliable and offer a low latency in sending small packets at a rate of about 100Kbps.

Z-Wave is a wireless communication protocol which operates on a low-power RF applications designed specifically for the control, monitoring and status reading in residential and commercial environments and used by about 250 different manufacturers in the world. It is in our opinion the best solution available on the market that can automate and transform your home into an intelligent building.

Mature, proven and widely distributed (with over 35 million products sold worldwide), Z-Wave is by far the world market leader in wireless control, bringing the “intelligent” products affordable, reliable and easy to use for many millions of people in every aspect of daily life. In Europe, the frequency of communication of the Z-Wave protocol is 864.42 MHz.

Each device / sensor Z-Wave receives or sends signals to the central unit where the software resides, the heart of the home automation system, which after having conveyed the various data coming from other sources with different characteristics (for example, we prefer to use sensors, thermo-hygrometric are of high quality and using transmission frequency 433MHz) shall monitor and control all events created for home automation intelligent.

The latest generation of devices Z-Wave Plus.
Z-Wave Plus ™ is a new certification program designed to help consumers identify products that use Z-Wave hardware platform recently introduced ‘Next Gen’, also known as the 500 series or 5th Generation Z-Wave. Products Z-Wave Plus also have a selected set of features and functionality that improve the end user experience can achieve Z-Wave systems even faster and easier to install and configure. The new features are many, including increased range, longer battery life, an Over The Air (OTA update), additional RF channels and more – all of which are fully compatible with existing Z-Wave products
