I have seen a lot of threads discussing false rain readings on the Tempest due to things like vibration, wind or birds but I don’t seem to have any of that, yet my Tempest after a rain event reads about twice the amount as nearby stations or even my old fashioned rain gauge. During the almost 3 weeks since I have had the station installed, I have never had a false reading where it showed it was raining when it was not. Today, we had a gentle rain that lasted several hours. My gauge shows around 0.25" of rain yet my Tempest shows 0.65" of rain. The previous rain event was also exaggerated by 2X. That’s a huge discrepancy. My Tempest is located above the roof of our house with no nearby obstructions like trees.
Will this accuracy improve over time due to RainCheck corrections or will I always have to rely on RainCheck to tell me the following day how much rain actually fell?
