Problem with temperatures below 0 degrees Celsius

[GoogleCodeExporter]

What steps will reproduce the problem?

1. Live in Norway
2. Receive data from Oregon temperature/humidity sensor
3. Wait for temperatures below 0 celsius

What is the expected output? What do you see instead?

The output from rfxcmd does not seem to take into account that the temperatures 
are below 0 degrees C

What version of the product are you using? On what operating system?
0.1g on Debian 2.6.18 kernel with python 2.6

Please provide any additional information below.

I am receiving the temperatures from my outside sensor on an Oregon Weather 
Station as well, there the temperature shows -0.6 C at the moment, but the 
output from rfxcmd shows 0.6 C.

This will be fixed in the upcoming version. You can make a short term fix in 
current version by changing line 699
from "if polarity == 1:" to "if polarity == 128:". 

This issue exists on other sensor types as well, which will be fixed as well.
