I see no reason why you can’t move to 2.3 and keep using the 1.x knx binding.
Right. Just thought about it and upgraded today just before your answer to check in my test VM. Looks ok, just cannot upgrade addons. Would need to spare some time next year to move my knx items to knx2.
Thanks guys for help. I’ll finally check your rules. I was actually forced to set it faster as my wife left recently garage door open for a night somehow.
