Just commenting here because I’ve struggled with this for a while. SetLevel commands are instant and it’s obnoxious when scenes are running, do to the delay in lights. It was like light bombs going off around the house. As of today, None of the “enhanced” device handlers provide configuration for newer (2015+) GE dimmers to actually ramp on setLevel changes. However, there is a hidden parameter not listed in the advanced config by the manufacturer. This param sets the ability to actually ramp on setLevel changes. Ie “set level to 90%” by default would be instant this param allows it to slow ramp.
Parameter 6
Value: 1
(Value 0 (default) =instant, 1=ramp)
Length 1 byte
Now the dimmer will slow ramp when setting specific values, not just Turn on/Off commands.
I don’t use the enhanced drivers, to change this I just changed the handler to “Z-wave Tweaker” and issued parameter 6 and value 1 change there. I then switched back to “dimmer switch” so local processing is achieved and all settings were retained.
