The weewx driver is here: https://github.com/matthewwall/weewx-sdr
I don't think it's complete, and there were some things I had to work out, but you can search for the answers here. One thing to keep in mind is that the pressure sensor for my Acurite system, and probably all the others, is in the display. If you bypass the display, you'll have to find another source for pressure. rtl_sdr is the Linux driver for the radio, and rtl_443 receives and decodes the transmissions from the sensors. http://www.rtl-sdr.com/ has general info on using sdr receivers based on the RTL2832U chip, which I guess is intended to be used for direct digital TV broadcasts in other countries. That means the radio and antenna you buy on ebay probably comes with TV watching software that will NOT work in the U.S. But once you've got the radio and the software installed, it's all a matter of tweaking it to get it working.
