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.

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.
