Re: Cheetah Generator Errors

[vince]

Are you doing anything unusual like running off a weewx tree out on a NAS on your LAN or the like ?

Did you change anything ?   

The logs look like it's having issues reading files including perhaps even your weewx.conf.   Is your SD card maybe going bad ?

[Tom Keffer]

Did you check line 570 in the skin.conf for the Belchertown skin?

 Thanks for the thoughts.  The whole system is on the raspberry pi, nothing on a NAS yet.  I don't recall any specifics what might have triggered it since i was slow to realize the problem.  I noticed the last date it was working was Jan 5 2021.   The only thing I have been doing with the system was trying to apt-get update to keep things current.   I did recently notice I was pulling the wrong source list (python3 instead of python2):

For python3 (debian10 and later):

curl -s http://weewx.com/apt/weewx-python3.list | sudo tee /etc/apt/sources.list.d/weewx.list

For python2 (debian9 and earlier):

curl -s http://weewx.com/apt/weewx-python2.list | sudo tee /etc/apt/sources.list.d/weewx.list

The raspberry pi is still debian 9, and running python2.7.   Once I updated this I was able to update from 3.9.2 to 4.4.0, but that hasn't fixed the problem.  

I hope the SD card is still good(only a couple years old, and weewx is really all this pi is doing).   My best guess is that i did an apt-get update that must have broken something last month that I didn't notice until recently.

I don't completely understand what is going on, but it looks like you're asking for cloud base in the belchertown skin, but the belchertown search list extension is not supplying a record from which to calculate it.

Most likely this is a bug in the skin, but it could be from the way you are using the tag. I assume it is something like $current.cloudbase?

I think i found it.   I must have been editing the graphs to change the new annual totals, etc after year end.   

I found a typo on line 570 of the graphs.conf file.    Now that it is fixed, things are a bit better. but I am digging into the graphs.conf file to see where I may have broken something.   Here is the latest syslog:

dunno whether this is a config error but the indentation and number of ‘[’s are not consistent here

[gjr80]

Unlike python, configobj has no specific indentation requirements, it's just us humans that like indentation. Square brackets on the other hand are important, in this case there would have been no error (the square brackets were consistent/matched) but [[Belchertown]] and below would have been ignored by CheetahGenerator.

[Graham Eddy]

that was my point. i think it was a subtle config error, not yet picked up by the authour, that did not cause a syntax error, but would truncate his expected reports. but, not knowing belchertown, perhaps this strange configuration was correct for it...
