There've already been a couple of community drivers for the SP600, but I make pretty heavy use of presence detection which wasn't included in other releases, so here's my take on it.
- Salus SP600 Smart Plug - Import URL: RAW
This makes it really easy to tell when a certain somebody has powered off the smart plug. 
Thanks to the other developers (where I learned how to configure the reporting intervals) and to @markus for explaining how to properly sendZigbeeCommands, which I also now use for raw commands in my AlertMe drivers.
