Technologies We Use
With conventional electrical installations, you have to determine in advance how and where your building’s switching systems will be installed, before construction even commences. But with KNX , you can keep your options open. That’s because everything in the system can be changed or extended at any time – without the usual mess and without laying new cables. KNX the only worldwide open standard for home automation and building system technology in accordance with EN 50090 .EN 50090 – the European norm for electrical installation technology for houses and buildings is based on the KNX standard. KNX is the only protocol that meets this norm. KNX is one system, one standard, many multi-task functions for maximum flexibility. In addition, all building technology devices and installations are connected via a single bus line, The two-wire installation bus routed in parallel to the 230 V electrical power supply connects all devices and systems of the household technology together, and transmits all the control signals. This is based on fast transmission rates with the highest levels of immunity to interference.
Zigbee is an IEEE 802.15.4-based specification for a suite of high-level communication protocols used to create personal area networks with small, low-power digital radios, such as for home automation, medical device data collection, and other low-power low-bandwidth needs, designed for small scale projects which need wireless connection. Hence, Zigbee is a low-power, low data rate, and close proximity (i.e., personal area) wireless ad hoc network.
Z-Wave is a wireless communications protocol used primarily for home automation. It is a mesh network using low-energy radio waves to communicate from appliance to appliance,allowing for wireless control of residential appliances and other devices, such as lighting control, security systems, thermostats, windows, locks, swimming pools and garage door openers.Like other protocols and systems aimed at the home and office automation market, a Z-Wave automation system can be controlled from a wireless keyfob, a wall-mounted keypad or through smartphones, tablets or computers, with a Z-Wave gateway or central control device serving as both the hub controller and portal to the outside.It provides interoperability between home control systems of different manufacturers that are a part of its alliance.
C-Bus is a communications protocol based on a seven layer OSI model for home and building automation that can handle cable lengths up to 1000 metres using Cat-5 cable. It is used in Australia, New Zealand, Asia, the Middle East, Russia, United States, South Africa, the UK and other parts of Europe including Greece and Romania. C-Bus is used in the control of domotics, or home automation systems, as well as commercial building lighting control systems. C-Bus uses a dedicated low-voltage cable or two-way wireless network to carry command and control signals. This improves the reliability of command transmission and makes C-Bus far more suitable for large, commercial applications than X10.
