Rough idea has two parts:
- small sensor device that I could attach to my mailbox. When mailbox door opens, a sensor will notice this event and save the data
- alarm clock application in my smartphone
Think about following scenario: I have set my phone to wake me up at 6 o'clock, but only if morning paper has been delivered. When alarm would ring, my phone asks (over Bluetooth, WLAN, ZigBee; you name it) from mailbox sensor when mailbox was opened last time. If mailbox hasn't been opened this morning (i.e. morning paper is late) my phone lets me sleep one hour extra. Application for terminal is nothing special, any mobile developer can do it. Any volunteers who are able to create a mailbox sensor appliance?
