5-in-1 Weather Station and web app history do not match........Why?

My 5-in-1 Weather Station base shows a high wind of 39mph and the web history only shows 32mph for yesterday.  Even the ticker on my base station shows the high wind of 39.  Why does the history on the web app show the high wind of 32mph?

because the Display is real time while the Hub that reports to MyAcurite.com is a sample at 5 minute intervals.  This is not measuring over 5 minutes but what it happening exactly at 5 minutes.  So if the 39 mph wind was not on the 5 minute snapshot, it will not be shown.  Just like taking a movie and then isolating just one frame.  The Display is the movie while the Hub to MyAcurite.com is a snapshot at that point in time.....

As I noted in my original post I was looking at the history from the previous day and not real-time. The ticker on my base even shows 39mph was the highest for the year on the previous day.

I forgot to mention that I’m using the new Access Hub.

I reread your post and I’m still a bit confused. Since my base received the transmission of the 39mph wouldn’t the hub receive the same one? Or does the hub query the weather station and wait for a response getting the reading from that moment in time?

Both the Access and your display receive the same signals as they are broadcasted by your 5n1 sensor every 18 seconds.

The Access however, only transmits data to myAcurite in 5-minute intervals.

A while back I took a look at the decrypted data flow from the Access to myAcurite, and it appears they are adding wind parameters the SmartHUB does not have, like an average wind speed calculation among other things (I can't remember if I saw a specific peak wind speed or gust calculation to myAcurite).  The difficult part, however, is trying to figure which of those windspeed parameters the myAcurite website and app are actually plotting.

Unless Acurite provides that information, someone may just have to do a intensive "stare-and-compare" between the transmitted wind parameters from the Access and what actually gets plotted.

Somewhere the author of  Acuparse and I were discussing some of the new Access parameters on his website, but I can't find it now.

I’m sorry to ramble on, but I think I’m starting to understand that it’s only grabbiing one sample out of multiple ones. My thinking is that works fine for tempature, humidity and pressure since it changes slowly. For wind that can change rapidly it should look at all the samples and use the highest one. Doing that will vastly improve the accuracy of the data.

rhis comment=suggestion was offered years ago. George might have snooped new data that Acurite does nor want to publish/use until more testing on it.
Acurite mentioned some time ago, they wanted to change how max wind and gusts were measured. it may sound trivial but there are lots of items that have to work to enable (from sensor to Hub to MyAcurite.com to GUIs o Dsiplays and PCs).

Acurite knows about peak/gust issues, 5 min time stamp vs real time Display, etc....
