Hi guys,

am running v3.5.0 with ultimeter 2100 system on a Raspberry Pi4

Weewx just stopped on me with this message:

Nov 23 06:11:34 weewx weewx[373]:     ****    File "/home/weewx/bin/weewx/engine.py", line 182, in run

Nov 23 06:11:34 weewx systemd[1]: weewx.service: Failed with result 'exit-code'.

Any ideas what's happening here and a possible fix?

Had been fine for about a week, so maybe this is just a once in awhile blip?

As in doesn't happen all the time?

Thanks

Chris

Hi, Chris

This is a bug that was fixed in V3.7.0, released 11-March-2017.

If you decide to upgrade, be sure to read the Upgrade Guide first. Not much has changed, but there are a few little details.

Thanks TK,

is there just a correction in the code I can quickly change, or is it more complicated than that?

In which case I ought to upgrade to the latest version....

In general it's always wise to just update to current so you have a setup that matches 'some' known version of weewx, in case you need future support.....or at least to the current version of your specific station's driver.

Just upgrade. It will probably be painless. If not, we are happy to help.
