1. To lock my access to Amazon after 10pm.
    No good purchases happen after that time.
  2. To remotely close windows at my house when it gets stormy and I'm not home
    Like an app on my phone that lets me know my windowsills are getting wet and I can just close the windows!
  3. Change which outlet a light switch controls without rewiring your house.

  4. To get Fitbit credit (and actual positive health impact) for the walking and running you do in your dreams
