Poking here first, but this may belong under the Beta / Z-Wave JS category...
I finally flipped over the Z-Wave JS (C8-Pro w/ 2.4.1.154) and lost my entire SmartStart DB. All my 800LR devices are present and functioning (in LR mode), but according to your app the SmartStart DB is empty other than two fresh entries I created.
Unfortunately for me, I never used your app to make a SmartStart backup, I only have the hub's cloud backup.
Thoughts? Maybe I just have to work my way around and rescan everything? In doing that would the SmartStart rematch scans with existing included devices?
I posted Beta Feedback here.
