Control KNX via HomeKit

Almost every smart technology comes with some kind of (mobile) application. Although KNX is already over 30 years old, there is no official app to control your system. Moreover, the KNX association talks about IoT and integration, but I couldn’t find real content, especially about the just-released Matter standard. There are many vendors selling visualizations and mobile apps though. Since I’ve already been using Apple’s HomeKit and Home app for quite some time now, I want to integrate KNX into HomeKit. In this post, I want to show you some possibilities, ranging from 0€ to ~1000€.
