Definitely. I had assumed it was some weird Sofaskin thing, but maybe no.

[weewx-user] Strange problems using FTPgenerator just started happening.

[Peter Neilley]

Hi! I've been using weewx on a raspberrypi for many years including 
uploading reports to an account on a cloud provider (1and1.com)  to post 
standard reports on my personal webpage.About 2 weeks ago I started 
having problems with getting the reports uploaded to the cloud via the 
weewx FTPgenerator process.  Digging through log files, I'm getting 
"connection refused" errors from the ftpGenerator process.   I didn't make 
any changes to weewx or the raspberrypi to trigger the errors, hence 
suspect something changed on provider's side.  

But the issue is strange and I can't figure it out hence posting here even 
though I suspect the issue is not weewx related.  Since there's lots of 
smart people here I thought I might get some ideas on how to solve it.  
 Here's some facts:

 1.  95% of the products I'm trying to ftp from weewx to the cloud account 
are not getting through.  Mysteriously, a handful here and there do make it 
through.
2.  I upgraded my rPi kernel to 4.19.x and weewx to 4.10.2 and no 
improvement in the issue.
3. I can manually ftp the products using the command line ftp program 
supplied with rPi linux with no issues at all.  Same if I use sftp or scp.
4.  I double checked my credentials in weewx.conf to make sure nothing was 
wrong with those. But again, the fact that some products get through 
suggests credentials are not the issue.
3.  log files in /var/log (both system.log and messages.log) indicate the 
weewx ftpGenerator process is failing with a "connection refused" error 
messages.
4. I can reproduce the error if I manually start a python shell and try to 
upload the files manually using ftplib in python.  I'm using python 2.7

This is telling me something about a new incompatibility between the python 
library in rPi linux and my cloud provider's FTP server is causing the 
issue.  But I haven't been able to figure it out.   So wonder if anyone 
here has any guesses and ideas.

Thanks for your support.

Re: [weewx-user] Weird error with days_ago in 3.8.0

[jterr...@gmail.com]

No sure if this is related to your errors, but it looks like the tag 
*$days_ago($days_ago=$n).dateTime.raw 
*is not correct.

According to weewx documentation, ($days_ago=x)  should be used with the 
*day* aggregation period   : *$day($days_ago=$n).dateTime.raw *

[weewx-user] Re: Belchertown / Graphs

[jterr...@gmail.com]

It appears that you are running weewx 3.9.2.  
The error you have shows that the new  belchertown.py (v1.3) script want to 
access to functions in  weewx.xtypes , which does not exists in version 
3.9.2

You will need to install weewx 4.0 or higher to avoid this error.

[weewx-user] Re: Embedding weather data from Weewx into webcam snap shot

[Gerard Cerchio]

I use ImageMagik convert 
to
 
copyright my webcam. 

convert snapshot.jpg  -font FreeMono -gravity SouthEast -pointsize 16 
 -fill "#fffdc3" -annotate +10+10 "(C) Gerard Cerchio 2023" snapshot.jpg

If you run your video at 30 sec a frame that might work out for you.

Re: [weewx-user] Weird error with days_ago in 3.8.0

[wxstor...@gmail.com]

Thanks Tom for your response. I have isolated it to that line of code. The 
line works perfectly when going back 350 days (setting $n=350) but not 360 
($n = 360). I have checked the database and there is data in there 360 days 
ago. I just don't get the real number not str error. There is no string or 
text in the dateTime column. I will keep digging around.
