For diming do you hold the paddle down?
Are you seeing any button pushed/held events for that device? In the manual I found it mentions scene control but doesn't saw how exactly, often this is with "CentralScene" events.
I do agree for this case the associations may actually be better due to the complications of trying to do smooth dimming through the hub. Also this particular device appears to have been designed with the intention of using associations.
Do you know what association groups you need to use? The manual I found does not list them: https://gocontrol.com/manuals/WT00Z-1-Install.pdf
I have a crude tool that would allow you to set any associations you want as long as you know the group numbers: [BETA] ZWave Tweaker port from ST (It can also scan the groups to see if the devices reports any info about them).
