RPi and Bootstrap template

[Nick Dajda]

Please feel free to add my site to the sample stations list...

Location: Royston, UK

It uses some (very unpolished) python code I wrote to show latest readings as visual gauges. I'll post the source at some point. It also uses Bootstrap for the general layout with everything running on a raspberry pi.

I'm really impressed with Weewx, it made the whole thing very easy indeed!

Done.

Nice looking site, Nick!

Thanks!

Not sure if the gauge generation code is any use to anyone however I've uploaded it anyway. www.dajda.net/nicksengines.py
My python is very rudimentary :)

I like those gauges! will have to see if I can steal some of those...

It actually looks pretty good. Really, you should break out the gauge imaging code from the reporting code. Then it could be used in other applications.

Is it possible to use the gauge_generation with mysql?

Not currently. It polls the archive.sdb database directly rather than go through the proper weewx helper services.

Although if anybody can recommend an easy way to read the last x number of readings then I'm happy to add this.

Currently it uses this SQL code to get the data it needs (from archive.sdb).

cur.execute("SELECT * FROM archive ORDER BY dateTime DESC LIMIT %d" % numPoints)

[Thomas Keffer]

That's exactly what you do, except you do it on an instance of Archive (NOT TESTED):

archive_db = config_dict['StdArchive']['archive_database']

archive = weewx.archive.Archive.open(config_dict['Databases'][archive_db])

for row in archive.genSql("SELECT * FROM archive LIMIT %d" % numPoints):

  print row

Thanks very much, this worked very nicely.

Hi Nick
I downloaded and tested your skin and nicksengines.py from your page, but when i started generate html pages i get this error. I thinks, you have some mistatekes there. Can you fix it (give gen to package, ...).

Hi Petr,

I believe this is fixed in the latest release (2.4.0).

This thread has some more information on this error: https://groups.google.com/forum/#!topic/weewx-user/jPapzLfhazQ

Hi Nick,
I discovered that problem is with generation of yeartempchill graph.It seems that can solve my problem. I try it. Thanks for info and quick answer.

Hi Nick,

I am using the fantastic skin you made, good job there! I seem to be having problems getting the gauges to generate the correct data, and the log indicates the input us wrong. Could it be the "Celsius" value after 1.0 that makes it to error out?

if so, is there any way to filter it out?

[Andrew Milner]

It's not the C - that is just a log string that is built for logging purposes.

Try and turn off the history setting for the gauge - should clear the error at least!!

Do you have records in the archive that cover the history period you have got specified for the gauge, or is it an empty (new) archive?

Are you using Nick's latest version of gaugeengine - I know that earlier versions had bugs related to None processing in several places.

Andrew

[Kenneth Edwall]

Yes, you are right! I installed the new version of of gauge generator.py and the error is now gone! But I still get some errors(even though everything appears to be normal?):

Have you checked your archive database to see if you have some strange values in there during the hours of history you are trying to display on the gauge?

What happens if you comment out history for the out temp gauge in the skin??  Can you attach the gauges section of your skin?  Do the other gauges (without history) work OK?

[Christian Müller]

Hi!
I also downloaded and tested this really very nice skin.
My Problem is that one of the Sensors (outTemp) of the Ventus W831 ran out of Battery and the Station is about 700 km far away :-(
The transmitted Value for outTemt is now "None" and the gaugeengine complains about this strange value an generates no HTML-pages.
Is it possible to turn of the outTemp temporary until the sonsor gets fresh Batteries?

 GaugeGenerator: outTemp, could not plot reading value of = None

The 'simple' way would be to just comment out the out\Temp gauge - so he does not even try and generate it.  Your error is coming from the histogram part though - so just remove the history line.  You wil stil get the onfo log about 'none' but will not get the error condition.  Also comment out the temperature tables - or get inside the code as it looks like it cannot handle all None for a month correctly - but that is an unusual situation!!  May be easier to just temporarily replace the history page with one that is fixed and says 'Not available' until you are able to sort it out!!
