I am currently using an SDR stick to read data from my Vantage Vue, using the rtldavis driver https://github.com/lheijst/weewx-rtldavis
I will probably move to a RFM69 based solution with an Arduino, has my SDR keeps dropping offline, and it will be nice to have multiple options anyway. I'll be using the meteostick driver https://github.com/matthewwall/weewx-meteostick when it comes to that. Now, I was curious and looked through the code and found that they both use similar (or maybe the same) code for wind error correction. I am however confused about this part """ The elder Vantage Pro and Pro2 stations measured the wind direction with a potentiometer. This type has a fairly big dead band around the North. The Vantage Vue station uses a hall effect device to measure the wind direction. This type has a much smaller dead band, so there are two different formulas for calculating the wind direction. To be able to select the right formula the Vantage type must be known. For now we use the traditional 'pro' formula for all wind directions. """ Later in the code, we see data['wind_speed_ec'] = wind_speed_ec data['wind_speed_raw'] = wind_speed_raw * data['wind_dir'] = wind_dir_pro* data['wind_speed'] = wind_speed_ec * MPH_TO_MPS So, it's pretty clear the code is using the Pro formula with it's dead band at north, and not the simpler Vue formula, which I think IS being calculate, just not used anywhere. # Vantage Vue wind_dir_vue = wind_dir_raw * 1.40625 + 0.3 What's the best way of telling the driver or WeeWX that I have the Vue hardware? I'm not so good at following the code through, so I am unsure where the 'data' dict ends up, and don't want to break someting by naively setting *data['wind_dir'] = wind_dir_vue* and calling it a day.
