Python-GH-DIVA: control GH components in GHPython?

Hello, 

I have a parametric setup in GH in which a DIVA simulation (Viper, Irradiation and Daylight) is run on each iteration and the results saved to an excel file through the gHowl plugin. I would now like to automize even more my simulation by using GHPython to control some of my GH components, identified in red in the attached (simplified example) file. Specifically, I would like to be able to (among other things):

- read and modify the value of a slider as well as animate it

- control a boolean toggle 

- know when a simulation is over

- enable/disable components (e.g. DIVA simulation and spreadsheet writer)

Are any of these possible? If so, any hints on how I should proceed with my Python script? I am just starting with Python and haven't found any resource on how to do such actions. 

Any help will be greatly appreciated!

Cheers, Emilie
