Not the GP but I use a simple wake up light alarm that was a game-changer for me in winters when a blaring alarm yanking me awake to a pitch-black room was not a great way to start the day, especially before going out into the -40° cold to scrape my car off.

A half hour before the alarm goes off, it slowly gets brighter which I find simulates the sun rising enough to be a more pleasant waking experience. Plus I set the alarm sound itself to bird chirps, starting with 1 or 2 birds and growing into a whole chorus (I'm usually up before then)
