Press Enter to terminate

Can anyone point mee at my problem.
I have a zip file of MX diags available

Please post the diags as asked, any info of what is wrong must be in the log.

MX diags zip
I have a problem attaching the zip despite being less than 15MiB

Have attached last service console and log

Added dayfile

OK, thanks. Last log and console should be enough for the moment.
Having seen the contents I think Mark must look at it to see where it goes wrong in the code.

Can you post your dayfile as well please.

Added dayfile above

Is your Growing Degree Days start month set to "7"?

Growing degree days data is all at default including 7 for southern hemisphere

I have noticed in today.ini the following first entry
"[General]
Date=4/03/2024
Timestamp=2024-03-04T15:00:00
CurrentYear=2024
CurrentMonth=2
CurrentDay=29"

Also noted in the 20240306-084314.txt that things appear to go wrong with the graphs generation

I've seen more posts like this.
In 2000 there was the millennium-bug. Is this the leap-year-bug?

Well the growing degree day graph data does actually use a leap year internally, but it uses the same year every year!

Whilst I investigate this, could you try disabling the Growing Degree Day graphs for me please?

Edit your Cumulus.ini file, and find the section [Graphs], then make to following edit...

Sorry, you will also need to edit the following entries...

You will need to do the same for the temperature sum graphs if you have enabled them.

I have found the problem, it affects southern hemisphere stations that do not have any data for January in the year they started. I've fixed this for the next release.
