emoncms - Problem sending data kwhd feed

Submitted by Guest on Wed, 05/09/2012 - 09:02

Hi,

I have a problem regarding data posting to emoncms. I have tried the example API URL which work OK. I autoconfigured the inputs and I see that the input and the feeds have been correctly updated with value 252.4. The power-kwhd feed has a value of 0.01 and the corresponding table in mysql has also the correct value.Everything is OK.

When I try to update it using a C# program or php with this code from the forum :

$url = 'http://yourserver/emoncms3?apikey=xxxxxxxxxxxxxx&json={power:252.4}';


$ch = curl_init();

curl_setopt($ch, CURLOPT_URL,$url);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

$contents = curl_exec ($ch);

echo $contents;

Then updated input value is 252 (without .4) and the power-kwhd is now 0 and will always stay 0.

I don't exactly understand what's hapening because the emoncs doesn't care where the request is coming from...

Is there any way to debug what's going on ?

Regards,

If you have access to the web server logs you could check what is being received by it.

Everything looks good in the apache log, I can see the exact string with power:252.4

You can find screenshots of my problem here : http://www.ploumen.be/emoncms/

In the apache log , here's what I see when using the curl or the test API method :

192.168.0.136 - - [05/Sep/2012:19:03:10 +0200] "GET /emoncms/api/post?apikey=6b9a3df24e73d977d849c61408f4968e&json={power:252.4,temperature:15.4} HTTP/1.1" 200 4386

I am using windows XP in french.

What can I do to debug this problem ? I realy would like to use this software.

Regards,

French? Isn't a comma used as a decimal separator in French? No idea how the various software layers would interpret this.

Yes indeed, the decimal separator is a comma. The problem is I have other software running on my server that need this configuration...

Anyway, it doesn't explain why it does work with the API test URL...

Ok I think I figured out what was going on. I changed the prefered language in the account tab and selected FR_fr (downloaded from the dev branch) and now it seems to work. I think this should be much more documented that the prefered language is linked to the input data format...
