just had some fun making a small monitoring client in C which use software rendered framebuffer graphics and the REST API, this should run on any embedded systems running Linux.
The client show the camera stream along with statistics about current / last job and temperature graphics.
The goal was to use a 2'8 TFT display on my desk for remote monitoring purposes and occasionally stream the framebuffer content to a remote service like twitch.
This could be adapted easily to monitor multiple printers or many other things.
