Upload to pachube

[stefferber]

I could not find a build in way in metehub to upload data to http://www.pachube.com.
Did I miss the information? Is there a plan for this?

Looks like nobody has a solution yet. Here is what I would propse and maybe you give me a feedback before I start implementing.

The goal is to produce an xml file accorinding to this style sheet http://www.eeml.org/ and send it to http://www.pachube.com feed. Pachube offers both push and pull.

• As I could not find a configurable "http push" in meteohub I will use the ftp upload mechanism.
• Putting a html file at "/graphs/pachube-template.html"
• Graph Uploads selecting "pachube-template *" every 5 Minutes with the target filename "pachube.xml"
• Configuring my web-page for FTP in "Set up Push services"
• Configuring the pachube feed to fetch the "pachube.xml" file from my web-site

Anything wrong with this?

Today I finished the above implementation. Below you find one template file for this feed https://pachube.com/feeds/2056:

Code: Select all

I have one problem left. How to change the formatting of the date-time string and time-zone in meteohub to the pachube format? Here is one example:

Code: Select all

Meteohub:  "20111223173934"

has to become

Code: Select all

Pachube: "2011-12-23T16:39:34.894650Z"

Any ideas?

Pachube can be triggered to send messages e.g. for twitter. Here is my first "debugging" event from my weather station. Really fun! Check out yourself at

Thanks a lot "wfpost"! This explain my syntax question very well.
But leads to the next question: Which time is measured here?

• Let's assume a sensor captures a value at time t0.
• The sensor transmitts data later to its console at time t1 (+ 2 min).
• The console sends data to meteohub at time t2 (+ 5 min).
• Meteohub publishes data to weather network at time t3 (+ 5 min).

As far as I understand the meteohub documentation, the above code would put time t3 in the html file, correct?
The difference between t0 and t3 could be 12 Min!
But I want to have time t0 in this file. How do get this information?
