The information about adding in some access to extra I/O on the OT2 is
in the wiki. Scripting information, including examples of using the
extra I/O for alarm reporting is also available.
Before I read the scripting information on the wiki, I hadn't written
any scripts for the OT2. I still haven't played with a 1 wire device,
but there's enough information about 1 wire devices in this SIG, and
on the net to be able to figure it out.
Go read the information in the wiki and start playing.
If you run into issues, ask away.
