The 20 years clearly underline that still besides this time, the area of house as well as building automation stays a extremely difficult topic, where there is still rather some work ahead of us, to make house as well as building automation ubiquitous.
2. For somebody that’s maybe new to KNX, can you explain what it offers to house owners as well as the different technologies it employs?
KNX messages can be transported over 4 different media: the primary medium is an own Twisted pair solution, however telegrams can likewise be sent wireless (868 MHz), on Powerline in addition to encapsulated in an IP frame. KNX has not only standardized its protocol, however likewise the configuration procedures for products. two flavors exists: the most utilized is by means of the maker as well as application independent software application package, called ‘ETS’ (Engineering tool Software), already in its 4th generation. The other configuration possibility is without the assist of a PC, a configuration called ‘easy installation’, i.e. with the assist of a central controller or by means of push buttons on the products to choose the channels of sensors as well as actuators to link. Last however not least, beneficial data in the telegrams need to be encoded according to the KNX standardized data types for functions for which such a standardized option exists.
3. one of the very best things about KNX is the number of new products being added all the time. Can you provide us some figures on the number of different KNX gadgets now offered as well as some examples of the variety of utilizes they can be put to?
Currently there are a lot more than 7000 licensed products on the market, utilized in different application domains ranging from Lighting, sun shading, security, HVAC, Monitoring, Metering, tons shedding, Scheduling, Audio control, …. etc.

5. lots of of our visitors are technically capable of installing a KNX system in their own house. nevertheless they are deterred by the extremely high expense of the software application needed to program the system (many other systems offer complimentary software). Is this a mindful decision on the part of the KNX association to keep out diy installers or do you have any plans to make it much easier for us to in shape KNX in our own homes?
Since the introduce of the ETS 4 software, a complimentary of fee version can be downloaded from our web pages: in contrast to previous generations of ETS, this version now likewise uses bus access, indicating newcomers can not only view the tool however likewise work with it, without any type of needed investment. The only drawback is that jobs are restricted to 3 devices.
There is nevertheless a version called the ETS 4 Lite, that comes at only 100 €, which enables the style as well as configuration of jobs of as much as 20 devices: if utilizing multi-channel KNX devices, already with this version, a moderately equipped single household house can be equipped.
When somebody is successful with the ETS 4 Lite version, he can upgrade to the full version, an investment that will then quickly pay off when doing adequate projects.

There is still a exceptional high number of house automation options that are proprietary. even options that are based on already offered requirements do not always result in products that make sure multi-vendor interworking. Interoperability is a remove possession of KNX, where high effort is put in ensuring the strict utilize of KNX standardized data types in KNX licensed products. In this way, the individual recognizes the KNX trademark as a token for true interoperability between material of different vendors as well as across different applications.
