KNX is a standardized, OSI-based network communications protocol for building automation. It is the successor to, and convergence of, 3 previous standards: EHS, BatiBUS and EIB.
KNX is currently the de facto standard in building automation in Europe. The KNX Association had 339 members/manufacturers from 37 countries. The KNX Association has partnership agreements with more than 30,000 installer companies in 100 countries and more than 60 technical universities as well as over 150 training centres. Member companies have more than 7000 KNX certified product in their catalogues.
Until recently, KNX did not have support for support for TCP. While there has been an IP based implementation of KNX named KNXNet for quite a while now, this protocol uses UDP as the transport layer, which is not very programmer-friendly and rather poorly supported in comparison with TCP.
Only recently did the KNX Association release a KNX Standard extension for KNX web services. This means that there is now an official standard for implementing RESTful web services, which makes it far easier to integrate the KNX eco-system with other technology:
The KNX WS specification foresees three flavors to ease the integration with an existing ecosystem: oBIX, BACnet/WS and OPC/UA.
The actual question
I'm currently having a basic KNX home automation installed in my home by a certified installer. I would like to purchase such a gateway to implement a custom web + mobile UI for my home, but I've been informed by both my installer and the KNX Association that no commercial solutions are on the market that support the new web services extention out of the box... yet (*). Neither seems to have any idea whatsoever when such a gateway might become available on the market.
Does anyone here know if any major brands are working on such a gateway and when the first gateways of this kind are expected to be released?
Are there currently conventional KNX/IP gateways out there that can be extended with KNX WS at the software level, so I don't need any additional hardware (like a NAS or a Raspberry Pi) to extend them with KNX WS support?
Unfortunately, this kind of information is very, very hard to find anywhere online.
(*) Note : While there are a whole bunch of commercial KNX/IP gateways, but none of these the brand new KNX WS standard, which has been released just a few months ago. The gateways currently on the market either only support KNXNet or some proprietary TCP-based protocol, neither of which are what I'm looking for!
