Step 1

For more information, please see my blog about this topic. Much of the text here is lifted from my blog, although I am making the effort to do more examples for this contest. There is a long (winded) explanation regarding MQTT topic formation that is more complete than what's provided here.

Step 2

Arduino Sketches for demonstration.
1) Ethernet Gateway Arduino

2) RFM Gateway Arduino

You'll have to make the modifications to the sensor node to match your pins. The only changes to the Gateway Arduino should be the mac address you want to pretend to be, and the IP address of the MQTT broker.
3) Garage Door sensor node:

4) Mailbox sensor node:
