Thanks very much Charles for this helpful reply! I've not had much luck to be honest with tracking down how to get a CGI script to work with NUT...but upon thinking my end-result I don't think having a webpage for each Pi to show UPS status would be used all that much. I'll stick to using a monitoring system to help me gather all my Pi UPS in one place for alerts.
Thank you, Charles.
