Right on the OZW integration page. If this is not appropriate to run the wizard for OZW, then the link shouldn’t show on that page:
I’m using the Z-Wave integration, which uses OZW under the hood. Are you referring to another integration that uses OZW directly?
EDIT
I’m going to try the instructions here and do it manually: Switching from Zwave 1.4 (Deprecated) to ZwaveJS2MQTT
Interesting step in these instructions that seems important about rebooting between removing the old integration and new one.
