My Vue consistently reads lower wind speed than the TV reports, and as an experienced motorcycle rider I can tell the difference between 15mph and 40mph wind. Problem seems to be turbulence caused by buildings, trees and terrain. First mounting was 4 ft above roof peak of barn. Moved it to a 21ft pole away from barn and the readings increased, but we are on a steep hill 200ft above a lake with tall pines about 100ft from ISS. I suspect it would require a much taller pole to escape the turbulence and get accurate wins speed.
Good information provided by others - especially by openvista.
Remember that, with a Vue, there is no way you would be able to duplicate "TV reports" for wind
and for temperature/humidity.
But the key question is: where do
you want to have measurements of the various parameters? Is it important to you, to know the wind/temperature/humidity at the top of a tall pole? Or above your barn? Or where
you live?
