Use your MagTag to show the current status of the James Webb telescope. NASA publishes this information to this official status page.
This GitHub project provides a server application that can parse the status page and return the current data as JSON data. We will fetch the data updates from this server so that it's in an easy format for CircuitPython to consume.
This project will fetch the data and display it on the E-Ink screen using displayio Labels then put the MagTag into deep sleep mode to conserve the battery. It will awaken to refresh the data once per hour, or once per day. Use the reset button any time to immediately refresh it.
