Thanks for the info/ideas Gary and Vince. I did a connection to a Google Sheet, and it now records the Tempest output every minute. Gives me the info I need to see if the rain fall amount is accurate. Will be comparing to a manual rain gauge at my station and to a nearby very good gauge. The issue that I am seeing is that the hepatic sensor cannot handle the heavy rain we have here in Panama. 2-4in/hr is not uncommon for some intervals. I am attaching a PDF of two stations near each other. One with an expensive, calibrated bucket rain gauge, reporting 5min intervals and the Tempest reporting 5min intervals (data from WU). In the red outlined area, you can see as the rain intensity increases, in the heavy rain, the Tempest in not correctly recording the rain accumulation. I understand that the precip rate calculated from the precip amount over time, that is amount/time=rate.
Now that I have the Tempest data recording to a Google Sheet and to WU, I can compare the numbers for transmission accuracy.
I do believe that the Tempests will have to have rain recalibrated to heavier rainfalls that is typical in the USA or Europe to function correctly in tropical downpours.
