I recently successfully built as system using a rooted Nexus 7, Raspberry Pi server, cheap flow meters, temp sensor and an Arduino Duemilanove. All worked very well for my 2 tap fridge setup so I am excited about putting this into real use.
Having now started my kegerator build I added another 4 taps so bought an Arduino Mega to make use of the 6 tap system.
However the Android App does not register the mega as a Controller. I can swap in the Duemilanove (even without the flow meters attached) and the App immediately registers it.
Do I need to edit the Arduino Kegboard Sketch in some way or add anything to the Mega Board to make it work?
