In the first years after 2000 I listen about ZigBee as a radio extension (ISM range 433 MHz) for collecting data in case of troubles with cabling. The ZigBee alliance was founded at the end of 2002. In 2007 ZigBee was completely revised. ZigBee profiles were defined for various applications (e.g. Light Link, Home Automation, Health Care). In practice, this was difficult because the manufacturers mixed them together. End of 2016 was development version “3.0”, which should be partly downward compatible and manufacturer-uniform. It is also the transition to IoT and in addition to the ISM frequency band 868 MHz (Europe) there is radio transmission in the 2.4 GHz range. A performance optimization of the system also enables the use of battery-free devices based on energy harvesting (self-powered). Now many light and luminaire manufacturers, but also furniture manufacturers have discovered the ZigBee for themselves, so this radio bus is actually a must-have in the home system. Due to the discovery of data leaks, improvements have been made again, development goes further. As with other radio systems, there are manufacturers who use this BUS but don’t promote it as such, because of some manufacturers, which do not follow to the standards or having obsolete devices in assortment. Due to the fact that WLAN is practically on board, the BUS directly embodies “IoT” and due to the large selection of lighting solutions, it is hardly possible to avoid considering this system.
