Charts and graphs not being populated with new data

[Gordon Dickens]

Hello all,

I'm running Weewx version 4.10.2 and Belchertown skin version 1.3.1 on Debian 12 with a Davis Vantage Pro2 weather station and console.  

Weewx and Belchertown had been running successfully for about six years and then yesterday, for some reason, my data console temporarily lost connectivity with my station.  So, I waited until it successfully reestablished the connection and then the console's USB port apparently stopped communicating with my Debian server.  So, I powered the console down, uninstalled the USB port,  reinstalled the USB port and powered the console back up afterwhich everything appeared to be working properly.  However, after an hour or so, I noticed that the weewx graphs and Belchertown charts were not being populated with new data. All of the alphanumeric data and reports appear to be correct but the graphs and charts are not being updated.

Does anybody have any idea what may have happened to cause this and how to potentially fix it?

Thanks very much in advance!

Gordon

If I had to guess, I'd say that your logger memory is corrupted, but without a log that's just a guess.

Here is some more info regarding this problem.  The attached file contains the pertenant sections of my logs that show lots of weewx.chetahgenerator errors after restarting the weewx service. The first error encountered is:

ERROR weewx.cheetahgenerator: Evaluation of template /etc/we
ewx/skins/Inigo/inigo-data.txt.tmpl failed with exception '<class 'TypeError'>'

Hey Tom,

In my previous post, I posted the errors from my log that occur after I restart weewx.  Please let me know if you want more of the logs or if that suffices for your review.

I powered down the console for between 1 and 2 minutes and then powered back up as per step 1 in the "logger memory is corrupted"  article entitled "Troubleshooting the Davis Vantage station" .  However, that did not help anything.  So, I attempted to use the weectl to dump and clear the memory, however, my system does not have the weectl command probably since I started weewx six years ago on version 3.x.x.  The apt command suggested that I get weectl by installing weewx, however, I don't want to upgrade weewx right now.  So, how do I get the weectl command without upgrading weewx?  Alternatively, is there another way to dump and clear the memory other than using the weectl command?

Thanks!

Gordon

Gordon - old v4 docs are at https://weewx.com/docs/4.10/

[Glenn McKechnie]

Weectl is for versions 5.x

I suspect you need the older syntax...

 wee_device --dump
 wee_device --clear-memory

which can be found on an older version of the page Tom linked to.

https://github.com/weewx/weewx/wiki/Troubleshooting-the-Davis-Vantage-station/7e6acff27411a560ec19a1bff8eea3a6f78b6a29

For all versions of the documentation...

You mention both Weewx versions 4.11.z and 3.x.x. The documentation for those versions is linked at 

https://www.weewx.com/docs.html

Cheers

Thanks Glen and Vince for referencing the 4.x documentation and the use of wee_device instead of wee_ctl.  I attempted to run the wee_device commands, however, more errors were generated.  The attached file includes the error dialog in response to "wee_device --dump" where the following lines are repeated several times followed by a Traceback dialog:

Unable to wake up console... sleeping
Unable to wake up console... retrying

I think that the console's data logger usb interface  has failed and may need replacing.  Any comments?

Thanks,

Gordon

Unfortunately, that is not a proper log, so it's hard to say what's going on. Perhaps you did not stop weewxd before running wee_device?

How to produce a useful log.

Hi Tom,

You were right.  I had forgotten to stop the weewx service before I ran the wee_device comands.  So, I went back, stopped the weewx service, ran the wee_device commands and restarted the weewx service afterwhich everything appears to be working now as the charts and graphs appear to be populating.  So, hopefully the problem is solved!

Thanks very much for you prompt assistance!
