Smart home and the Internet of Things (IoT) have greatly developed during the last few years. Thanks to them, controlling our home blinds or lights from wherever we are, is becoming a common task nowadays. The main technology and responsible for this amazing development is KNX. A communication protocol that makes really easy to design a connected smart home. ABB, one of the most important manufacturers of control equipment, has developed free@home. A complete system to have a smart home.
Free@home based on KNX
Different communication protocols are available to set up your smart home. You can find ZigBee, X10, Z-Wave, etc. The two most important and remarkable are LonWorks and KNX. While LonWorks is more common in USA, KNX has ‘won the competition’ in Europe becoming the most used protocol for smart homes.
A KNX installation is based on a BUS cable that connects all the elements of your smarthome. The main advantage of KNX is that it is an open standard. That means that you can use products from different manufacturers in your system. Furthermore, it can be easily scalable just by connecting the new items to the BUS.
