Weatherflow Smart Weather Station came Monday, I set it up Tuesday (remarkably easy) in anticipation of rain Yesterday.
Watching the temperature, dew point and humidity data it is within a degree or two of my Rainwise. Wind data won't be good until it gets on the roof. Folks on the WF message board have reported wild rainfall errors like a foot of rain in one storm. While I did not see that, the results weren't perfect. Lets hope the self diagnostics WF speaks of are not just hooey and the data gets better. Here are my results from yesterday:
Rainwise Tipper 1 (just cleaned Tuesday) 1.05"
Rainwise Tipper 2 1.00"
Weatherflow Smart Station 1.20"
Cocorahs 1.07" (most rain in my state today!)
Also, this bright, sunny morning the Weatherflow reported .004" at 7:13am. It is temporarily set up on my deck until I can get my son over to help me mount it on the roof. I suppose it is possible the ultrasonic sensor detected my movements, but if so why only the one time?
