I am using the Raspberry Pi B+ to build something of a home automation system. It has EnOcean Wireless Sensors, some arduinos and MQTT and a CC3200. I am also going to add a Rover based on the RPi soon. Then there is the RPiSOC that is also involved.
Here is my LONG and painful video of the final system Description and Demo
And Some more... Feat. The Raspberry Pi Telepresence Robot!
