Batcave Operating System from the Lego Batman Movie
When you say "Ok Google, I'm home" then your Hue lights will turn on and set a scene of your choice, then your phone will begin playing the song of your choice, so you too can feel like Lego Batman! Unfortunately, this applet won't tell you the whereabouts of your, spouse/butler, or what mail you received during your away period. It also only works with Android Phones, due to inter-app communication restrictions in iOS. Enjoy!
