Once Zelda: Breath of the Wild out on the Nintendo Switch, this dude decided it was time to automate his home. The system is based off the ocarina from The Legend of Zelda: Ocarina of Time. Allen Pan used an internet connected Raspberry Pi, connected to different gadgets for his home automation system.
Playing Zelda’s Lullaby locks/unlocks the door, Sun’s Song toggles lights, Bolero of Fire turns on heat, Song of Storms controls the humidifier, and so on. He can even play a tune to unlock his car!
