Automatic on?

[ftb28064212]

Hello! I would like to suggest a new feature (or see if it's something that's already planned). For now, I'm fine with manual control of the switch but I would like the option to reverse the logic and have the outlet turn on after a print, rather than turn off. The plan is to mount a small AC fan above my CR-10 and use the smart outlet to control it. The CR-10 takes a fair bit of time for the bed to cool down after a print, and I'm using the Creality glass bed that needs to be cool before trying to remove parts. It would be nice to have the fan automatically turn on at the end of a print (and possibly turn off after a set amount of time).
