1. To lock my access to Amazon after 10pm.
    Static
    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.
