Youtuber Sufficiently Advanced demonstrates his Raspberry-Pi driven home automation system. It executes different chores when it hears the associated ocarina tune from Ocarina Of Time. When he plays Zelda’s Lullaby, the front door unlocks, when he plays the Bolero Of Fire, it turns on the heater, and when he plays the Sun’s Song, it turns on lights. The possibilities for this invention are endless and continue to significantly improve home automation systems. It’s not yet on the market, but they may soon offer as the video goes viral.
