Hi @shafy sorry for the delay I was away for few times.
Before we start please read the Support Procedure - About AI-Supported Development. Keep in mind we are not there to develop for you neither integrate or guide you with 3rd party module that you will most likely need in order to control knobs.
With that's said what you are asking (at least retrieving a parameter and defining it) is possible for Redshift light intensity. It is as easy as drag and dropping the parameter you are interested by into the Cinema 4D Python Console as explained in Python Script Manager Manual - Drag And Drop. Additionally you can also use the Script Log to record a script or change and therefor re-execute it.
Cheers,
Maxime.
