Honeywell ZW3005 Dimmer Fade Rate

Most Z wave devices have two different parameters for fade rate and ramp rate: one which is used when the switch is physically pressed and one which is used for network commands such as scenes.

If you get the parameter setting information from the device manufacturer, you should be able to set them with the Z wave tweaker.

Remember that you need to set both the number of steps and the interval. If you only have one step, it doesn’t matter what the interval is it’s going to jump to 100% each time.

From one manufacturer:

Dim Rate Adjustments
Both the number of steps (or levels) that the dimmer will change and the timing of the steps can be modified to suit personal preferences. The timing of the steps can be adjusted in 10-millisecond intervals. As an example, the default setting for parameter 8 is “3”. This means that the lighting level will change every 30 milliseconds when the Dim Command is received. A value of 255 would mean that the level would change every 2.55 seconds. Combined, the two parameters allow dim rate adjustments from 10 milliseconds to 4.2 minutes to go from maximum-to-minimum or minimum-to-maximum brightness levels.

And don’t get confused about zwave “setlevel.“ That just means the device is dimmable. It doesn’t tell you whether or not the ramp rate is adjustable.
