8 months ago I started my home automation journey with Home Assistant Supervised with a Rpi4 running on a SD card. In trying to keep WiFi devices to a minimum, I went all in with Z-wave devices (about 25) with a GoControl HUSBZB-1 USB Hub and I have pretty happy with this set up. I am now spinning up a 2nd instance of Home Assistant Supervised on a 2nd RPi4 but on a USB SSD. So far this has been working well as I’ve added the few WiFi devices I have with no problem as well as all the various add-ons I found useful on my 1st instance.
My question is how best set up or, migrate my Z-wave network/devices to the SSD instance of Home Assistant Supervised? While I’m open to buying a 2nd GoControl HUSBZB-1 USB Hub, I don’t think a z-wave device can belong to 2 different networks at the same time. I also want to avoid repairing 25+ devices again if at all possible. My main concern is keeping my Z-wave network/devices on the 1st instance operational until I get it fully set up on my 2nd instance. If anybody has experience with this, or any advice, I would really appreciate it. Thank you.
