I don't know if this becomes its own plugin or part of this one, but whenever I print with OctoPrint, the fan stays on indefinitely after the print completes. I have worked around this by adding GCODE to the end of the print to wait 5 minutes (to allow hotend to cool down), then turn off the fan. This however makes all my build time estimates be WAY off (it says it will take 40 minutes instead of the actual 7). I think with the timeout code you already have in this plugin it would be easy to add in an auto-shutoff of the fan if the machine is idle and the hotend is below a threshold.

Recently, I've started to print more from SD card, rather than from Octoprint and I found some issues which I believe might be triggered by the HeaterTimeout plugin.
Reproduction scenario:
Prusa MK3S + MMU2S
Octoprint at Raspberry Pi3B+ connected via dedicated pin header on Prusa Einsy board
OctoPrint 1.4.0 running on OctoPi 0.17.0
HeaterTimeout (0.0.1) settings:
Polling Interval 15s
Heater Timeout 600s

1. During preparation for print, I set preheat on Prusa directly to heat up extruder for cleaning
   it usually takes a few minutes.
2. After my extruder is cleaned I've select print from SD card on my printer directly.
3. The printer starts all sequence to load filament, adjust heat table and extruder to a given temperature
4. printer do table leveling and start printing
5. After a few minutes (which I believe is about 10 min starting from preheating) printer switch off heating of extruder and bed.

My assumption is that HeaterTimeout didn't detect that SD card print have been started in the meantime and triggered switch of heating

Hi,

thank you very much for this very cool plugin!

It's a bit annoying that I always get the notification, that the plugin was activated on my printer screen, and that I need to remove them one by one.

Is it possible to add a setting that these announcements are disabled?

Cheers
Martin

Reproduction scenario:
Makerbot Replicator 2X
Octoprint at Raspberry Pi3B+ connected via USB cable from Printer to pi
OctoPrint 1.4.0 running on OctoPi 0.17.0
Heater Timeout 600s
Duriing a normal print on the Makerbot Replicator 2x, I Recieved notifications every 15 seconds after 10 minutes passed that the Heater Timeout heater idle timeout Triggered. see attached screen capture. The print continued, but the messages filled the screen. I notice you made a recent revision to hide notifications and I will give it a try.

When a print is paused the heaters will timeout even though the print is still active. This causes carborundum glass beds to release the prints.
