I have three printers; each uses a raspberry pi that runs OctoPrint. I wanted to be able to give people a single page to see all of the webcams, what they are printing with ETL (est time left), and what the current temperatures are.
This demonstrates how I did that. Email me at richard@hamstudy.org if you'd like to see a live demo -- I don't want every bot on the web looking at my cameras and using CPU cycles.
