My printer has a loud fan and blinky lights and so I turn it off when I'm not using it. My Octopi does stay on but it doesn't like losing the serial connection to the printer and makes a big fuss about it.
I'd really prefer if the default behavior for losing the serial connection was just a big red OFFLINE indicator. And for Octoprint to occasionally (once a minute?) poll the serial port and if it comes back online, it goes back online automagically.
Seems a more user friendly thing to do. Or at least have the option/plugin to do.
