Nothing will be misunderstood, and I always try to do my best to help, but perhaps you should consider to stop calling by "bug" everything that just not work the way you expect it should work.

SORRY.

I can't edit my message forchange the title and remove the term "bug".
As for the wind, you tell me something. I always thought that the wind speed was the instantaneous speed at the time of transmission.
My brother is passionate about weather and has done manual surveys for several years, it is for him that I make this one.

I'll look for the wind vane. It is a simple REED contact with a single magnet.

thanks for your help.
