Sunshine today

[olli395]

Hello everybody,
For a few days now the display of “ sunshine today ” has only been counting up! Yesterday morning there were already 29.2 hours of sunshine (?)
Since I haven't changed anything, I can't explain it...
Does somebody has any idea?

What build/version are you running? I have 3.28.6 build 3283 and today’s sunshine is calculated correctly.

Could you please zip up your MXdiags log file and attach it to a reply to this topic. The file should cover the end-of-day rollover time.

The CMX version: Cumulus MX 3.28.5 b3282

Zip up the whole folder and attach it to a reply. It looks as if you are restarting MX hourly. MX is designed to run continuously.

Hello Freddie,
too big to attach (71.8MB)...
You can download here: https://www.solat.ro/MXdiags.zip
Where is the hourly restart defined, - so I can check (?) *
thx, Olli

*Found it: was an error in the crontab:
I added:

Code: Select all

0 * * * * /sbin/shutdown -r now

instead of

Code: Select all

0 0 * * * /sbin/shutdown -r now

to reboot at midnight...

...just thought about it: the rollover is at midnight... could this be the problem?
To be sure I changed the cron now to

Code: Select all

30 0 * * * /sbin/shutdown -r now

, to restart 30 mins later...

midnight is the worst possible time to reboot if you are using a midnight rollover, which is when Cumulus is doing its end of day processing which will mess up all sorts of things, including daily sunshine.

[mcrossley]

Do you really need a daily reboot anyway? I often leave my Linux running for months between reboots.

Also, make the reboot at a time when a log entry isn't being created, so 00:32 say.

I just deleted the entry in crontab... I did this because the PI "froze " once in a while and the reboot resolved it, until the powersupply died... Finally this was the issue...
Maybe this is also the issue for the wrong sunhours (?)

[mcrossley]

As I said above all sorts of data will be incorrect because the overnight rollover processing has been interrupted. Your rainfall will be wrong for example. The sunshine hours is the least of the problems.

Example:

Code: Select all

[olli395]

This did the thing!
After deleting the cron, it works fine now!
Thank you all
