Some Newbie Questions

Hi there. Just started working on an Arduino project, with the ST Shield. However, I do have some other ideas, and I was wondering…

  1. Is there a WiFi implementation yet?

  2. Where can I find documentation for the Z-Wave messaging, as supported by the ST platform? I see the messages, I have seen the code on the arduino examples to process it, but where can I find the specification for that?

  3. Thanks! This stuff is great so far, though I think the intro documentation is a bit out of date.
