If no one else replies with a better answer you could look at
https://github.com/glennmckechnie/weewx-uradmon which takes json values on
a uradmon and injects it into a DB and then has a skin to display graphs.

If you are willing to get your hands dirty I came up with code to do this:

https://github.com/evilbunny2008/weewx/blob/61173c762fd30b33251ec304cbc3864c08c96eee/bin/weewx/imagegenerator.py

You just stick that in /usr/share/weewx/user/ assuming you installed from a 
deb file

In my case I'm using a modified Standard skin I 
put user.imagegenerator.ImageGenerator to replace the weewx standard 
ImageGenerator

Can you tell me what weather station you are using?

My guess is your station isn't spitting out as many variables as other 
stations.

Wouldn't using high charts be able to do some/all of this?

I too was after this and I submitted a PR but I'm yet to be told of a 
simple way to do it without patching manually patching things.

I've just published a new version of the app (0.5.13) which now exposes the 
underlying exception strings.

The previous way was to show general descriptions and these weren't, in 
hindsight, as useful in solving problems with config settings.

[weewx-user] Re: Android weather app for weeWx users

[John Smith]

Just to give everyone an update, I've been adding getting some really great 
feedback about the app and requests to implement new features.

However one of the changes requires adding an additional field of 
$day.windGust.max.formatted 
to be added to the data.txt.tmpl file. I've uploaded templates with the 
changes so anyone using the app just needs to download install it.

wget 
https://github.com/evilbunny2008/weeWxWeatherApp/releases/download/0.3.4/data-0.3.4-imperial.tar.gz
wee_extension --install data-0.3.4-imperial.tar.gz

OR

wget 
https://github.com/evilbunny2008/weeWxWeatherApp/releases/download/0.3.4/data-0.3.4-metric.tar.gz
wee_extension --install data-0.3.4-metric.tar.gz

Changelog

0.3.4 - Shifted about to the main settings drawer and added a zoom option 
to the stats page
0.3.2 - This release adds more caching so it doesn't try updating when 
manual updating is selected.
0.3.1 - Fixed bugs when authentication isn't used.
0.3.0 - Added a drawer layout for settings, added the ability to specify a 
username/password in the URL for settings.txt and data.txt
0.2.25 - Added an option to show forecast on first page
0.2.22 - Added code to wipe settings, fixed up forecast code to be a little 
better
0.2.21 - Added code for weatherzone forecasts
0.2.20 - Fixed crash when update in the background was unticked.
0.2.19 - Removed the refresh button and added SwipeRefreshLayout to most 
screens so manual updates work similar to other apps 
0.2.18 -- Added manual refresh button to the settings page for those that 
only want to update manually.
0.2.17 -- Bug fixes to prevent app from crashing if the data.txt file has 
unexpected characters.

I just added a manual refresh button on the settings page, although long

of refreshing everything

After waking up properly, it seems they are utf-8 chars and for what ever 
reason the method I used to download and parse them isn't working, I'll try 
to work out a proper fix, but for the time being I just pushed out an 
update that strips non-ascii chars which then works with your settings

[weewx-user] Android weather app for weeWx users

[John Smith]

Just to give some background I made an android app similar to Pocket PWS. I 
liked the app, but it was closed source so I couldn't do anything to add 
new features.

With Tom's blessing I named the app weeWx Weather App and I have published 
it to google play 
https://play.google.com/store/apps/details?id=com.odiousapps.weewxweather

To use the app there needs to be some small changes made to weeWx, to 
automate some of the steps needed I created a pair of weeWx extensions, one 
for metric and one for imperial units.

I've outlined the installation steps on 
github: 
https://github.com/evilbunny2008/weeWxWeatherApp/wiki#concise-instructions

All comments and requests about the app should go to 
github https://github.com/evilbunny2008/weeWxWeatherApp/issues

Have you tried adding the username and password to the URLs?

eg
http://username:passw...@mydomain.com:777/cgi-bin/video.jpg

[weewx-user] Re: Generating files less often

[John Smith]

I wanted to create a yesterday report similar to the today report, which 
worked ok, but it kept generating images even though I had stale_age for 
the report. I fixed this by adopting the stale_age code from 
cheetahgenerator.py and putting in a slightly modifies imagegenerator.py

It was most likely due to the ten year graphs I generate.

I'm using a rock64, bit quicker than a rpi, with 4G of ram and usb3 for the

stale_age it completes in about 4-5seconds before it was take 150-160s

Thanks for that,  stale_age seems the easiest way to go.

I've looked through the documentation and nothing jumped out to me, I'm 
wondering if it's possible to generate the monthly and yearly templates 
daily instead of every archive record received.

Not sure if this is any help to you but I did a 10 year page (522 weeks) 
and used the following:

$span($week_delta=522).outTemp.max at 
$span($week_delta=522).outTemp.maxtime.format("%d/%m/%y %H:%M")

Why not just put the current timestamp as a parameter...

filename.png?time=

This is usually enough to stop caching in all browsers, without needing to

[weewx-user] ten year graphs

[John Smith]

I'm relatively new to weewx and have successfully imported data from a 
previous weather station, and so I have 9 years or so of data and I'd like 
to have ten year graphs.

I managed to get graphs by copying yearly sections in the skin.conf file 
and bumping time_length to 31536, but the problem is the axis values 
overlap each other and there are far too many axis bars.




Any help would be greatly appreciated...

Did you try to stop it then start it, I had the same problem with the 
/etc/init.d/weewx method, it won't start if it dies for what ever reason.

Re: [weewx-user] Re: After Updating to Latest Version of Ubuntu I get Segmentation fault (core dumped)

[John Smith]

To latest version 16.04 I did a " do-release-upgrade " I am running a 
server, not graphical linux.


And Ubuntu is up to date ...

root@dzone:/# do-release-upgrade
Checking for a new Ubuntu release
No new release found


if I do apt-get install owfs it reports latest version,

root@dzone:/# apt-get install owfs
Reading package lists... Done
Building dependency tree
Reading state information... Done
owfs is already the newest version (3.1p1-2ubuntu1).
0 upgraded, 0 newly installed, 0 to remove and 6 not upgraded.

apt-get install weewx does not make sense however 

root@dzone:/# apt-get install weewx
Reading package lists... Done
Building dependency tree
Reading state information... Done
weewx is already the newest version (2.6.4-1).
0 upgraded, 0 newly installed, 0 to remove and 6 not upgraded.

Because I was previously running 3.5.0  as per the web pages that 
were uploaded before the unbuntu upgrade ...


What I imagine I will do is re-install v3.5.0 weewx and use the backed 
up copy of my weewx.conf  and suck it and see  not sure why 
linux chose to downgrade weewx or sees an older version ... however I 
did have a very full boot partition, and was a bit cramped for room, 
which is why I chose to tidy up the os in the first place. Perhaps 
somewhere along the way it lost its way ... which I seriously doubt, as 
all appears to be very stable at the moment ... owhttp reports the 
attached 1 wire devices ... so it appears to be a python thing ... or a 
lack of permission to use the usb resource  although I have tried 
that with udev .. rules.


A bit of a mystery. Getting a bit peeved at the 1 wire setup anyway  
looking very hard at a pi 3 or a dual arduino setup in the future  
after all it is a hobby :-)
