Our ETS3 and ETS4 software generations have been discontinued for many years now. From 1st March 2021, the replacement of dongles for these products will also be discontinued. In the case you would have a lost/stolen/broken ETS3/ETS4 dongle needing a replacement, KNX Association will replace it with a Host-ID version (linked to PC) instead. This replacement will be offered free of charge.
Important: in contrast to the dongle version, the Host-ID license can only be used on one single PC.
If you still own such a product, we strongly encourage you to update it to the newest version, which is provided with a mini USB dongle and for which KNX Association gives full support.
