PIT daylight analysis using custom Perez epsilon, delta

Hi

I’m trying to run a daylight analysis using a sky model where I can input custom Perez sky clearness (epsilon) and sky brightness (delta). I don’t want to use any particular weather file but rather use custom sky parameters.
I was also looking through GENDAYLIT which takes epsilon and delta. But I’m not familiar with how to work with gendaylit through grasshopper.
Is there any way I can create a custom sky using HB/HB+ which let’s me plug epsilon and delta parameters? Or, how do I work with the gendaylit file to input epsilon/delta and use it in daylight simulation using Grasshopper?

Thanks!

Still trying to solve this issue. Anyone has any idea how to incorporate epsilon and delta parameters in the sky model in HB?
Any help will be much appreciated!
