It does appear that the new 1.6 OZW Daemon does check in with the device database on start up and will pull missing configuration files. If you check the logs of the integration you will see it attempting to pull missing records from http://download.db.openzwave.com/. So theoretically once it shows up in the device database on openzwave.com, it should be pulled into your config directory after a restart. If you don’t want to wait, you can locate your core_zwave data directory on the host machine and pull it manually as the Inovelli Support page (listed above) describes. The location of the core_zwave data will depend on your installation method (This can’t be done through either SSH addon, and isn’t support by Home Assistant so use caution.).
