Your last point interests me. How are you correlating the cloud cover (actual) vs readings? By visual observation?
Have you thought of doing a correlated image acquisition analysis from a camera and the readings from the sensor? I’d be interested to see the specs on the FOV of the sky sensor and see if it could be mapped to an image taken at the same time.

Rob,
I'm using visual feedback to collect the actual cloud cover. I've built a data logging function in my app to collect the raw model input parameters from the sensors together with a manual cloud cover input and write that to a CSV file. The actual model development is in Excel.
Cloud cover percentage is a bit subjective visually and I assume this would also be a challenge using a camera image.
The IR sky temperature sensor that I'm using is a Jaycar XC-3704. You can download the datasheet from their webpage link:

The packaging says it has a +/- 40 deg FOV.
