Hello,
First off here are my details:
- Raspberry Pi 3, Raspian 9 (Jessie)
- Davis Vantage Pro (model 6160)
- Serial to USB, connected at /dev/ttyUSB0
- Python 2.7.9
- weewx 3.8.2 (according to my weewx.conf)
I am a long time (since 2008ish) user of wview and made the switch a few
weeks ago to weewx. The install went smooth, moved my sdb files over, but I
couldn't see any pages being generated in the html folder. I have lurked a
bit here and read about how to set the debug level in the weewx.conf and I
have been watching the logs. I also haven't had a ton of time to sit down
and think things through until today. What I have been observing is, I
believe, weewx can connect to my data logger and download data, parse it,
and insert into the sdb. There is a odd thing happening though, the date
time stamp is in UTC but the time zone designation is Pacific Daylight Time
(which is my time zone). After weewx downloads from the data logger it
tries to connect to the console, and start the "main loop." It's here that
the program crashes and exits. I have attached the log
(mainLoopError_NoneType.txt), if you take a look you will see that weewx
acknowledges that my raspberry pi's clock (PDT) is less than the UTC time
coming that the record has (my vantage console has the PDT time displayed).
Also you will see in the log file that at line 1677 in the vantage.py file
is where the program crashes. It looks like the value passed into the
_null_int() function is null and the function cant return the integer of a
null value. So, here is where I decided to try and handle the error. I
edited vantage.py and added an if statement to only return the integer if
the value is not None. I don't really know the repercussions of doing this
because I haven't dug through the entire program to trace out what this
value is.
> # Try to handle NoneType error
>
> def _null_int(v):
>
> if v is not None:
>
> return int(v)
>
>
After saving and restarting weewx the program doesn't error out and my html
pages are finally generated! Very exciting but I am wondering if anyone
here has the experience to know why my console was sending a null value and
whether my error handling will have any negative effects. I am attaching
the log file after my little fix for your review too
(afterEditVantagePy.txt).
Thanks, I am excited to get this up and running!
Mike
