Googlefu has failed me.  Is there scheduled mining support?  When Summer hits I'll have to deal with Smarthours, sometimes the kWh cost will hit 0.44/kWh and I'm often not at home to unplug the systems during these events. And I'm forgetful.  I'm looking for some way to tell the S9s to stop mining and use just minimum power for about 5 hours a weekday.  I usually have a day's warning on when high cost events will hit.
