Missing Day of data from weather station

[Prospect]

I have a Weatherflow Tempest using installed since Wednesday 17th January 2024 but on Sunday 21/1/24 (the Storm Isha) which I would like to see in CMX as these contain record wind gust 73 knots and rain etc.

The Tempest history is there on the Tempest app/pc program but not getting into CMX.

Any suggestion why a day would go missing?

Hi
I have attached all the text files from the MXDiags.

Initally when first set up CMX I had the wrong StationID I corrected yesterday, but I have data for 17/01 to 20/01 and 22/01 onwards and complete gap for the 21/01/23 which due to the record winds/rain I would like include.

Regards

Craig

The oldest log file there 22 Jan 16:49:36, attempted to download data for the period 20/01/2024 17:30:00 to 2024-01-22 16:49:43 but got an error message...

Code: Select all

2024-01-22 16:49:44.064 Error downloading tempest history: {"status":{"status_code":404,"status_message":"NOT FOUND"}}

Which presumably had the incorrect station-id set.

The simplest way you could recover the data now you have the station ID set correctly....

Restore a backup from the /backups folder that was just before the date/time you want to recover from (with CMX stopped!).
Do not restore the Cumulus.ini file, just the /data folder.

restart CMX and it will request history data from that backup time to current. You will of course lose any "live" data from then until now and be relying purely on the historic data.

Hi Mark

Thanks for your reply, the oldest backup folder is 2024-01-22 the day after the record winds etc.

Tried CreateMissing going back to 17/1/24 but in the charts still going a straight line between the day in question.
I had the Tempest on a tripod from 17/1 to 20/1 (in my gargage overnight) and installed on its pole on Sat 20/1 when it was safe due to ice previous days so if you can open the image there willbe early straight lines where no readings from 16:50 on the 20/1 till 17:00 on the 22/1.

The data is not missing on the Tempest app

The only option left to you I think is to follow the rather a tedious process to fetch the missing data from the station history and manually combine it with the current data.

1. Stop Cumulus and make TWO backups of the /Data folder somewhere safe.
2. Delete all files in the /Data folder except today.ini
3. Edit today.ini and delete all the content leaving the following lines...

   Code: Select all

   [General]
   Date=10/04/2012
   Timestamp=10/04/2012 10:00:00
   CurrentYear=2012
   CurrentMonth=4
   CurrentDay=10

   Where you the set the date/time you want to recover from - I suggest starting at least the day before.
4. Start Cumulus, it should download all the data from the date you entered above until present.
5. Stop Cumulus again
6. Make a THIRD backup copy of the /data folder
7. To ONE of your original /data backups made at the start...
   1. Edit the newly created dayfile.txt and extract the day(s) you want to recover
   2. Paste those days into the backup dayfile.txt, overwriting any entries already there
   3. Edit the new Jan24log.txt, extract the lines for the periods you are missing
   4. Paste those lines into the backup Jan24log.txt, overwriting any that are there
8. Copy the updated backup folder that you just updated back into your Cumulus installation folder.
9. Start Cumulus, it should resume from the point where you stopped it at 1. above
10. Your missing data should now be visible in the select-a-period etc
11. Finally use all the records editors to check if the previously missing data exceeded any records

Phew, I think that's it, if it all goes wrong you can restore from the second (unedited) backup you created at the start and be back where you were.
Just take your time, think about what you are doing and don't leave blank lines it files etc.
