I'd like to be able to use a remote WiFi outlet to power down the printer later in the day when away from home after a print finishes and I won't be back for hours and hours. I'd rather not just kill the power without doing the proper software shutdown first. I know we can add custom G-codes after a print, but that won't talk to the RPi if I'm thinking right. I've programmed different computers over the years, including a little on the RPi, but I haven't gotten around to looking into this one yet. If someone points me to an easy answer, that's the first choice. Second choice is some more digging into this.
