Title: pywws setup on Rpi
Post by: MattHB on April 06, 2013, 09:55:49 AM

hi all,


im having trouble setting up on my RPi.


weatherstation testing checks out no problem, all read.me instructions followed for weather.ini.


with livelog I get this error in the log file.  it sems to be having trouble finding the .xml files, even though th path in weather.ini is find and the files are present.  permissions are set to 777.


any ideas? Im running out of brain.


cheers

Hi Matt,

Try a new fresh copy from archive for the xml file.

If not ok, remove the call to that xml file in weather.ini
to see if it could continue processing without that file.

Hope this help,

Regards,
Jacques

Cheers ill try that.


Am I right in my understanding that its this line that's failing?

Code: [Select]

I've tried replacing all the XML files in the plot directory with the ones in Jims examples directory.  I've even used a new templates directory elsewhere and set permissions to 777.


I'm still getting a 'no such file or directory' error.


Any further ideas?

I've just remembered I didn't try taking out all the plot file references in weather.ini.


I've just done that and it got to the FTP bit before it errored (which is good as I can work on that).


So it does seem to be something with the XML files.

Ok nearly there now!


Turned out I'd not installed gnuplot!  :o


One final problem.  When it tries to FTP I get 'name or service not known' in the log file.  What have I missed/forgotten to do this time?


Cheers

Hi Matt,

'name or service not known' refer to your FTP login informations.
see in weather.ini if your FTP user/password are ok.

Example weather.ini:
site = ftp.MyWeatherSite.com
user= ....

Jacques

Wow.. What an idiot. I put ftp.domain when I know full well it won't work! So fixed thanks!


I do have one more recurring issue. Occasionally I get an error like this..

Code: [Select]

Exception USB.core.USBError: USBError(None, 'Unknown error') in <bound method Device.__del__ of <usb.core.Device object at 0x12f7ef0>> ignored.


I'm a bit clueless

Hi Matt,

For that one I have not encountered this error, then since a software issue,
have to refer you to pywws support list (https://groups.google.com/forum/?fromgroups#!forum/pywws).
