Tempest vs Vue
txagwx:
I have both a Tempest, Vue, and a Cocorah.
The tempest overestimates rainfall. Yesterday, Vue .04", Cocorah .05", Tempest .14". The rainfall algorithm is still decent though.
The tempest also underestimates gusts vs the Davis, sometimes by a significant margin.
The radiation shield on the tempest is by the far the best I have seen, especially with the small size. Wonder if they use a combination of solar and wind to correct?
Anyway, my two cents.

Totally agree especially regarding the wind gusts. Had a wind of 51 mph during a thunderstorm on my Davis Vantage Vue and the Tempest peaked at 32 mph. NOT ACCEPTABLE! Sold it the following day.

How do you know your particular Davis unit is accurate? They both could be off.

The difference between 51 mph and 32 mph is fairly obvious. Would not be difficult in determining which one was rubbish

I just added a 20% correction factor to the gust, and it works.
The other problem I am having with the Tempest is the battery is already going low on me, 2.5 volts, was 2.8 volts earlier this summer.
