Is your enhancement related to a problem? Please describe.
The printer already turns off the hot end and the bed heating procedure after a period of time in idle condition(safety feature). However, the printer state becomes BUSY and hence, unresponsive, until the LCD knob is pressed. This is quite an inconvenience when the printer is being accessed remotely via PrusaLink / Prusa Connect and one needs to go to the printer and press knob to make the message go away and put the printer back into READY mode.

Describe the solution you'd like
Add a timer to remove the message automatically and put the printer back in to READY mode without the need of pressing the knob (user acknowledgement).

Further, the serial output in this state is merely "paused for user". I can work around this by disconnecting and reconnecting Octoprint, but on blind faith, as the serial output is too generic. AFAIK there's no way to read the display from the serial port
