To ans your quest. about the temperature:

I have a 1-wire system and don't yet have the
barometer module.  My temperatures from the
humidity module and the main weather station
(which are 2 feet apart) are usually within
a degree of each other.  I only record the
temp from the weather station.
You can see my graphs at:

The main problem is that the OpenTracker doesn't support the barometer
module yet.  A user was nice enough to loan one to me for testing, so when I
get a chance I'll see what I can do.  What's the model number of the
barometer unit you've got?

Is the temperature correct when the barometer module isn't plugged in?
