My Raspi upgraded to openhab 2.3 during an apt-get operation. I did not intentionally upgrade but thought that no harm would occur. After the upgrade I noticed that my knx 1 binding was uninstalled and I noticed the new KNX 2 binding. As I dont have the time right now to do the migration and my whole setup is largely based on KNX, I would like to revert back to my KNX 1 binding. As this is no longer present in PaperUI I need some help from you. Can you tell me the necessary steps ?
