I don’t know if you know this project:
the realization is really simple and everything works with ASCOM and the weather and cloud cover data are saved on TXT file.
The system is based on classic weather station sensors and in addition it has a sensor that reads the sky temperature via the IR sensor to determine the cloud cover.
Is it possible to insert the reading of data from this station into Voyager? looking at the PDF they show that SGP reads them.
