Just installed my Sky and went through the first rain event. Few observations.
Installing Sky did create a minor rainstorm which I successfully was able to delete from the archives.
There was one very brief/minor rain event registered to Sky yesterday afternoon that did not happen. Bird? (I have added no bird protection measures yet but probably needed due to high local bird population.)
There appeared to be several rain started messages from the App when there was no rain observed and also not reported on Sky.
There was at least two minor sprinkle events that did not fully wet the pavement that did not trigger a reading in Sky.
It rained overnight with Sky registering around 0.46" inches of rain while my Cocorahs rain gauge located about ten feet away registered about 0.19." (Wind was low through the event generally less than 10 mph. FYI my impression on wind readings so far is that it appears to be a little low but could be accurate based on less than perfect siting. I think the wind gust chart seems to reflect airport wind average pretty well based on initial observations so pleased with that.) At one point, I noted that it read “extreme” which I myself would have classified as a moderate heavy downpour. (Edit: Total storm total per Sky 2.45". Actual rain gauge reading 0.87".)
See attached photo of Sky. It is 7 or 8 feet off the ground on a small ridge overlooking a very large field. I used a 10 foot high fence post from Home Depot per recommendations found at this site and installation was quick and easy. The metal pole was cemented into the ground and appears to lack any vibrations.
I understand that there will be a calibration period for Sky to go through so will be interesting to see if the initial overestimate of rainfall goes away in subsequent events which should come later today, possibly tomorrow and couple times next week. (Note: I was one of the lucky winners of receiving 2 SKY units for the price of one! I do plan on returning it after I receive a prepaid postage from WeatherFlow as I would hate for somebody else having to wait any longer than necessary for their unit!)
