Yeah, I left the SmartStart provisioning entries in Z-Wave JS UI for all applicable nodes. I also kept the DSKs in a separate spreadsheet (because it’s a pain to remove faceplates from every light switch/outlet/etc.). They seemed to work ok. Then I had a bit of a disaster on my Home Assistant thanks to the dumpster fire that is OS 16 (see HERE for what restoration took).
When I finally got Home Assistant back, I had to reinstall Z-Wave JS UI, and my SmartStart list was empty. Now whenever I paste any DSK in, it says that it is invalid. (Tried for ~10 different devices…)
