Dawn/Dusk Simulator

Hi all,
I'm looking for an efficient way to recreate my dawn/dusk simulator with my hubitat, please.

I have a zwave smart switch controlling a bunch of Zigbee lights. What is like to have happen is:

If it's after sunset and I double tap the paddle to off, gradually decrease the light level of those lights from 100 to 0 over 15 minutes.

Likewise for double tap to on.. From 0 to 100 over 15 minutes. (I will extrapolate this to a dawn alarm at 6am)

Is there an easy way to do this, please?

Thank you in advance.

Believe RM has a fade over time, use the double tap as a trigger, fade up if off, fade down if on…

Thank you.. Where do I set double tap as a trigger, please?

I don't see that option in RM; my options are Battery, Certain Time, Cloud End Point, etc (including Dimmer, Switch, and many others), but no Double Tap.

If your switch supports the double-tapyou should see it as an option IIRC.

Thank you. I'll swap out the ge for a zooz.. In the mean time, I'll try a virtual button.
