Console/data logger

[Altocumulus]

I thought - and hoped - the data logger on the Davis stations would store data when there was a battery backup installed. It is, and fresh batteries.

We had a power outage at 0600, returning at 1100, Otto struck.

The graphs, for wind, on MX shows a gust of 55 kt this morning at 0600, then a straight line to 1100 - suggesting a break in storing?
Although I don't expect the normal fine detail, I expected to see data showing between 0600-1100.

Then onto the today/tomorrow page, highest gust shown is 36 kt.

OK - there's no dayfile for yesterday whilst the power was off at the 0900 compile this morning - is that why the data stream isn't updated? MX downloaded data from the logger starting at 0% - so a full data drop.

Am I expecting too much?

Hi,
Your datalogger should and probably has the ongoing data. Not sure what happened to CMX when power failed, but yours is a typical instance were you can stop CMX, copy all the files from a previous good backup - i.e. CumulusMX\backup\daily\backupwithpreviousdayroller and paste into your \CumulusMX\data folder over top the existing. Start CMX and it should catch-up data from data logger from that last backup to current.

As always, make a copy of your existing working CumulusMX folder just in case!

Enjoy,
Paul

We have relatively frequent power outages where we live; it's quite rural, with a lot of trees and frequent large winds. That said, we have an ethernet data logger installed on our Davis Vantage Pro 2, and it does record sensors during a power outage as long as the batteries are up to snuff. I'm not sure what the update interval is, but it is noticeably longer than normal. Maybe something like every 5 or so minutes.
