The SprinklerSwitch project has FINALLY been updated to support the latest version of Raspian. The biggest hiccup was switching to the WiringPi2 library - which is now the defacto library for addressing GPIO pins. The good thing is pin addressing is now entirely in userspace (no sudo required!), however there were significant changes that required refactoring.
Things are up & tested with the latest version of Raspian however - so have at it!
