I have a large installation of Leviton DZ6HD and DZ15S switches with DZ00R-DL remote switches for 3-way and 4-way applications. I have 2 issues:
The remote switches do not correctly display the dimming level when the master switch is off.
The master switches do not report the correct z-wave status to the Smartthings Hub when using the remote to operate the master.
Levition technical support is providing me with a zwave USB dongle and Levition OTA firmware updating software. The software and firmware can be downloaded here. This may be a temporary link but it’s working now.
