Re: [mh] HAI Omni II

Brent-

I added a bunch of stuff to mh/lib/Omnistat.pm a while back to make
if functional with HAI thermostats, so you may be able to use parts 
of that to get your code functional.  As I recall, getting data back
from the Omnistat was one of the more difficult problems.  I'm not
using the Omni controller though, just an RC-80 thermostat.

Hope that helps some.
