I have mine to set to go into deep standby after I think 2 hours of being put into normal standby.
I have set a daily reminder for BBC1 HD at 5pm, this brings it out of deep standby and set ready to view BBC1, it also gets the guide fully populated for when I what to watch at around 5:30-6pm
After seeing the lunchtime news today about the lost Morecambe and Wise tape, I thought I would give remote scheduling a go. Just checked now and the Aura has successfully set the timer, so it looks like my routine works.
If I was to not watch the Humax it would automatically power down after the set idle time in the settings.
