Extreme data mixed up & not showing

[monkey38]

This morning I started the pc as it was loading I cleared the memory off on my N.Geo touch screen. I opened the cumulus program let it load and under the recent extremes I have none of my yesterday info I looked under the Dayfile.txt and saw that there was no info safed for yesterday's date so I created that I closed and reopened Cumulus and it still didn't load yesterday's info but changed my max wind gust to 11.4 mph for 14:45 this afternoon (which is 8 hrs away yet) I went and checked under the data file and all the info is listed under Yesterday. Could someone send me in the right direction on where to find how to get the info corrected and get yesterday info listed.

Thanks

It's failed to do the end of day rollover, for some reason. But if this:

means what I think it means, then the reason it couldn't do the rollover was that the data wasn't available. Just to clarify - you cleared the station's memory before you allowed Cumulus to download the data it needed to catch up from the previous day?

As an aside - it's not necessary to clear the station's memory at all.

Steve:

You are correct in what I did I thought the memory had to be cleared so it would keep everything current. I thaqnk you so much for your help.

I thought the memory had to be cleared so it would keep everything current.

The memory stores the data from the sensors so that Cumulus (or any other software) doesn't have to be running all the time (although it is better if it does). When Cumulus starts up, it checks to see when it was last running, and downloads the stored data from the station for the period since it was last running, to get up to date. If it can't download the overnight data, there are gaps in its stored data, and it doesn't do the end of day 'rollover', so all the daily statistics are then wrong.

Even if the station's memory indicator shows the memory as 'full', it still isn't necessary to clear the memory, as it just starts reusing the 'oldest' memory locations. So as long as you don't leave Cumulus not running for so long that the oldest data gets overwritten before Cumulus has had chance to download it (e.g. about two weeks at a 5 minute logger interval) data won't be lost.
