Hey Guys,

does anyone know the Youless energymeter?
there is a wiki here

I bought one andwould like to get some data of the youless into PH...
The postman (who always rings twice...

) will deliver it monday 31st

found some php-code:

Code:

<?php

 //////////////////////////////////////////////////////////// ////

// Script to read minute data of Youless te lezen

//

// 

//

// Result showm as echo on screen

 //////////////////////////////////////////////////////////// ////

$sserver='localhost';

$sdatabase_name='';

$susername='';

$spassword='';

//$con = mysql_connect($sserver, $susername, $spassword) or die('Could not connect: ' . mysql_error());

//$condatabase = mysql_select_db($sdatabase_name, $con) or die ('Could not select database' . mysql_error());

 //////////////////////////////////////////////////////////// ////

//Bijhorende tabel

/*$sql="

CREATE TABLE IF NOT EXISTS `YL_data_minute` (

  `id` bigint(20) unsigned NOT NULL AUTO_INCREMENT,

  `tijdstip` datetime DEFAULT NULL,

  `meting` float DEFAULT NULL,

  `kWh` float DEFAULT NULL,

  `kWh_cumm` float DEFAULT NULL,

  UNIQUE KEY `id` (`id`),

  KEY `YL_minute` (`tijdstip`)

)";

$result = mysql_query($sql) or die("Query failed. create table  ".mysql_error());

*/

$richd=json_decode($json);

     //$row = mysql_fetch_array($result);

     //$max_tijdstip=strtotime($row[0]);

     //$cumm=$row[1];

     //echo date('Y-m-d H:i:s', $max_tijdstip)." ($max_tijdstip) - $cumm<HR>";

for ($i=0;$i<count($value)-1;$i++){ // Lees de meetwaarden in de array

     }

     else echo "rejected: $i, $tm, $dt -> ".date('Y-m-d H:i', $tijdstip).", $value[$i]<br>";

}

?>

was found here: http://gathering.tweakers.net/forum/list_messages/1494214 (dutch language)

and this short piece to get the total readout of the meter:

Code:

<?php

///Get Youless data

$url="http://192.168.0.14/a?f=j";

$handle=fopen($url, "r");

$json="";

$json=fgets($handle, 1000000);

$Youless= json_decode($json);

$YL_meterstand=1000*str_replace(",",".",$Youless->cnt);

echo "Youless meterstand: ".$YL_meterstand;

?>

Hey guys,

need your help for starters I would like to import the
current powerconsumption using http://192.168.1.14/a or with http://192.168.1.14/a?f=j

for some reason my code returns only 0

Peter,

Would need to see your code to know why you're getting a
0. Since it looks like this meter has a web interface,
you can probably scrape the data using the URLScraper
plugin.

To get going though, I would run this function:

ph_geturl("http://192.168.1.14/a?f=j")

and post the results.

Dave.

The result is:

Code:

HTTP/1.0 200 OK

Content-Type: application/json

 {"cnt":"134,828","pwr":983,"lvl":21,"dev":"(±8%)","de t":"","con":"OK","sts":"(08)","raw":88}

The CNT is the metercount since startup
The pwr is the current powerconsumption
The LVL is the lightlevel which is reflected by the meter
The DEV is the lightlevel which is responsisble for detecting a puls

the rest is of no importance, been trying to get the powerconsumption by putting the ph_url function to [LOCAL1]
and then with ph_setglobal_s("YOULESSTEMP1",ph_regexdiff1("kWh,Watt",",","[LOCAL1]",1,2,0,0,0)) but the string always is emtpy...

Peter,

Your ph_regexdiff1 function needs some work.
Particularly since the LOCAL1 var will contain double
quotes, you'll want to use ph_getvar_s(1,1) instead of "
[LOCAL1]" (variable substitution). You'll also want to
delimit your strings within the function with single
quotes instead of double quotes to work around this
issue.

I was going to bang it out real quick for you but the
biggest problem is your search strings. According to
your function, you're trying to return data between the
string "kWh" and "Watt" (I think) but neither of those
strings appear in the returned JSON data.

Dave.

Peter,

Reread your post and since you state you're interested in
returning the powerconsumption value (the value
identified by "pwr"), I went ahead and did the function
below that will do that for you:

Code:

ph_regexdiff1('"pwr":','"',ph_gevar_s(1,1),1,1,0,0,

0)

Of course, this assumes that LOCAL1 contains the returned
data from the ph_geturl function.

Hope this helps,

Dave.

I am getting a synthax error:

here is the macro

Code:

insert into macroheader values ('HVACPWRCONS','HVACPWRCONS',0,0,1);

insert into macrodetail values ('HVACPWRCONS',1,15,'[LOCAL1]',NULL,'ph_geturl("http://192.168.1.14/a?f=j") ',0,'','');

insert into macrodetail  values   ('HVACPWRCONS',2,10,'YOULESSTEMP1',N ULL,'ph_regexdiff1(''"pw r":'',''"'',ph_gevar_s(1,1),1,1,0,0,0)',0,'','');

  insert into macrodetail values ('HVACPWRCONS',3,36,'',NULL,'{YOULESSTEMP1}',0,'','');

I went on and changed the macro to this:

Code:

insert into macroheader values ('HVACPWRCONS','HVACPWRCONS',0,0,1);

insert into macrodetail values  ('HVACPWRCONS',1,38,'',0,'ph_setvar_s(1,1,ph_geturl("http:// 192.168.1.14/a?f=j"))',0,'','');
 
insert into macrodetail values ('HVACPWRCONS',2,36,'',NULL,'ph_getvar_s(1,1)',0,'','');

insert into macrodetail values  ('HVACPWRCONS',3,10,'YOULESSTEMP1',NULL,'ph_regexdiff1(''"pw r":'',''"'',ph_gevar_s(1,1),1,1,0,0,0)',0,'','');
 
insert into macrodetail values ('HVACPWRCONS',4,36,'',NULL,'{YOULESSTEMP1}',0,'','');

and got the same result:

Peter,

Didnt look at your second macro and just went with
troubleshooting the first. The problem is a typo (that I
originally made).

Within the ph_regexdiff1 function, the get variable
function should read ph_getvar_s instead of ph_gevar_s
(the "t" is missing).

Also, you'll (sometimes) have problems with the last line
of your macro unless you enclose {YOULESSTEMP1} within
single or double quotes (if YOULESSTEMP1 only contains a
number, you'll be ok. If it ever contains a string, it
will fail. Putting quotes around it fixes it for all
datatypes).

Dave.

Yep, it is working now, crazy that I did not find the typo

Now I can go on and extend the macro with more functions like history etc. The usermessage was just used for checking what was in LOCAL1, it can be removed now.

The first thing I did was make this:

Now it would be nice to get the totalcount in here too but that is for later

Here is the same meter with the totalcount:

code used was:

ph_regexdiff1('"cnt":"','"',ph_getvar_s(1,1),1,1,0,0,0)

Here is some more work on the youless... what I've done is get a basic Chart-script and convert this for PH and added a calendar which says what the total used electricity is on each month and the used kWh so far for the running month.

to get this data into PH is pretty basic. On the last day of each month I put the metercount into a GV and subscract the last month from the totalcount.

here is a screenshot:
