For over a a year and a half now I have a successful OH1 install running on a Raspberry.
The system runs most of the house, rollershutters, blackouts, gates, lights, hvac, etc etc, and is composed of a mix of several devices: several raspberry’s connected to relay boards, ESP8266’s, and finally a few z-wave devices.
I’ve setup a test raspberry with OH2, and I’d like to migrate my system. I have a few hundred lines of code with rules and items - I’m not just going to drop them on the new install, I’m going to make a fresh install and rewrite everything, as the OH1 was written while I was learning, so there is much to clean up.
Most items are no problem, as they are setup with MQTT.
My problem is with the ZWAVE devices. My question is, are the zwave network settings/pairings/node numbers saved in the USB pen? If I unplug the USB pen from the OH1 raspberry and plug it into the OH2 install, can I use all the same node designations, or will I have to pair up every device again and start fresh?
