Re: [weewx-user] Re: Change archive interval for single report

[A.J. Burnett]

Hi Gary...

I never did THANK YOU for all your help with this issue from months ago. I 
got it all to work very well, thanks to your assistance! It is much 
appreciated!

I'm working on another station/page for work now and have a similar but 
different issue that I'm hoping you can assist with.

I have installed the realtime gauge data extension on a RPi. The same Rpi 
is hosting the intranet page to display the data. I've set up the guages.js 
script to write to the directory I need gauge-data.txt to go to, but the 
file is not making it there.

weewx root = /home/weewx
skin = [weewx root]/skins/ss
HTML root = /var/www/html  // This is where I'm hoping to get the realtime 
gauge-data.txt file to, every 2.5 seconds or LOOP packet generation.

My syslog is attached as a .txt file (shows the file being generated, but 
no more info available).

Any thoughts?

Thank you once again!

A.J.

Sorry, meant RTSG (Real-time Steel Guage).

Re: [weewx-user] Re: Change archive interval for single report

[A.J. Burnett]

So I've managed to get the JSON file to update every minute, but would love
to get it every 2.5 seconds. I installed the SGRT skin, but still only get
the file every minute. What should I be doing now?

Thank you all for all your help!

[weewx-user] Re: Change archive interval for single report

[A.J. Burnett]

Hi Andrew,

Station type is a VP2. My StdArchive interval is set to 300, which should 
be every 5 minutes, but the gauge-data.txt file only updates every 10 
minutes. My web page only updates at that same 10-minute interval too.

[weewx-user] Re: Change archive interval for single report

[A.J. Burnett]

UPDATE:

I stumbled across SteelSeries Gauges and saw that it produced a great JSON 
file (and has some cool gauges to go along with it too!). So I have a JSON 
file now, but I want SteelSeries to update every 2.5 seconds (near 
real-time). I can't find that interval anywhere...right now, it appears to 
be every 10 minutes.

Any ideas on how to get the 2.5-second interval going?

[weewx-user] Re: Change archive interval for single report

[A.J. Burnett]

Hi Gary,

Thanks so much for your response! I'll admit, I'm very lost.

I have done some minor customization to templates and have some basic 
Python knowledge, but I'm not understanding the steps in your very detailed 
message (thanks again!)

Perhaps harnessing the loop packets is the way to go, since I'd love to 
display the data in a "rapid-fire" manner, similar to Wunderground's very 
frequent updates.

How do I go about accessing those and spitting it into JSON format?

A.J.

[weewx-user] Change archive interval for single report

[A.J. Burnett]

Hi everyone!

I'm producing a simple JSON report using weeWX, in addition to all my other 
reports. I'd like to keep the interval I'm currently using for everything, 
but I want to fire off the JSON report every 5-10 seconds, if possible. Can 
anyone recommend where I can achieve this, if it's even possible?

Thank you!
