@br0nd ok - so after reading up - I am confused (and nervous about bricking my system - even with a full backup).
I read this: addon-zwave-js-ui/DOCS.md at be8c002cd73362fdd734559d98f317a650b0c828 · hassio-addons/addon-zwave-js-ui · GitHub
and reread this: Switching Z-Wave JS Addons with Minimal Downtime! Z-Wave JS (Official) to Z-Wave JS UI (Community)
They are a bit different.
If I just follow the addon-zwave-js-ui/DOCS.md at be8c002cd73362fdd734559d98f317a650b0c828 · hassio-addons/addon-zwave-js-ui · GitHub, then it seems to be a 4-step process. No uninstall of Z-Wave JS.
If I follow this Switching Z-Wave JS Addons with Minimal Downtime! Z-Wave JS (Official) to Z-Wave JS UI (Community), Steps 9, 10 and 11 are not in the github based instructions. In fact, step 11 appears to have me remove Z-Wave JS ? I thought the Z-Wave JS was needed and reused, and Z-Wave JS UI simply added in an additional menu/screen?
I get that steps 5 through 8 are backing-up and reinstalling - device/node configuration in case something went wrong.
or - am I over thinking this?
