I have a ZEN31 driver I created, that device is actually made by Fibaro, may be the same thing and just re-sold by Zooz, not sure. I would have to compare the manuals, do you have an exact model number or a link to the manual?
Also you could try using this tool to scan for all the settings if you want, it does not work on all devices, they need to support some newer command classes. [RELEASE] Z-Wave Universal Device Scanner
I think on the ZEN31 if you are in effects mode via the parameter and then send color commands it takes it out of effects mode right away. So maybe your devices has slightly different firmware. I know for sure setting the parameter to 0 disables the effects mode.
