Help adjusting ramp speed on light switch (GE Embrighten)

BTW, If all you want is just to change the ramp rate, I would suggest instead of using the custom GE DTH, just use the Z wave Tweaker. This is a special utility DTH which you can use with any mains powered Z wave device. It is only used for configuration. You temporarily assign your device to it, change the parameters to however you want them to be, then you go back to using the original DTH. Because the parameter values are saved in the switch itself, they will still be the way you change them.

It’s a very cool utility, and it also has very good documentation. If you have any further questions about it, ask in the author thread for that code and someone will help you there.
