Lists of interesting things to do with Vera, or HA in general?

Just wondering if anyone has come across any long lists of things people have done besides the obvious things like lighting/shades/etc. I’m looking for more complex stuff, like some of the things I’ve done:

  • RFID transmitters in the car to automatically open the garage when they return
  • Sending a command to an Android phone which starts Scanner Radio playing my local police feed into a whole house audio system
  • Voice alerting over the speaker system when the garage doors are open for more than 5 mins and the outside temp is under 55 degress
  • Building a little relay thingy which trips when power is cut to my “off-peak” power feed and alerting via voice and sms

I’m looking for complex scenarios that may require additional equipment or communication to other types of devices to accomplish a task.
