Not a problem, I'll leave the SoundSensor lines in there for the future and just mimic a motion sensor for now, as that's the device it most closely resembles in behaviour.
If anyone's interested I've got pretty much the whole AlertMe device range sorted with custom drivers now, with presence detection, save for the Lamp (a bit more complicated) and the Display (not a clue how to deal with this one).
They're available at the top of the AlertMe Device Drivers thread.
