User Michael H from the KNX user forum has developed a KNX plugin which we have had good feedback about.
You can find the KNX plugin and details here. Please keep in mind it is all in German, so you will need to use Google Chrome or similar to translate the page. It should also be noted that the video guide is also in German.
KNX integration has been discussed many times on our Google Groups. Click here to perform a search for KNX on the Google Groups.
