Hi, I have done some more research and it looks like there was a change in RTL_433 at tag 19.08 (August 2019) that changed the naming convention for a significant number of wind related fields for lots of sensors. I guess sdr.py needs to be updated to take this into account. I would offer but my main programming was over 20 years ago and have never programmed in Python so I would probably do more harm than good.
