Seems the button-press used (on the H9000) to Restart after updating H9000 software ought to be able to be accessed from inside Emote. Maybe the same could be true of a button-press to Shut Down the H9000, instead of trucking on over to wherever the H9000 happens to be and hit that Power button.
True shut-down probably not, since the power is hard-wired. But restart is possible, since we use this already in the Emote software updater. We'll consider adding a dedicated button in a future release.
