Summing several counters

Posted: Tuesday 25 April 2017 12:15

Hi, I have 3 energy meters (pulse counters) for three separate phases, how to make a virtual device that will show me the consumption of kWh for all three?

Create a time script where you update a virtual device with the sum of the others.
Code could be lua, php, bash, whatever you like.
If you like to go with PHP I can help you or even provide a example.

This should work:

Code: Select all

<?php
$sumusage=0;
$sumtoday=0;
$domoticz=json_decode(file_get_contents('http://127.0.0.1:8080/json.htm?type=devices&plan=3'),true);
if($domoticz){
    foreach($domoticz['result'] as $dom){
        $usage=number_format(str_replace(' Watt','',$dom['Usage']),0);
        $sumusage=$sumusage+$usage;
        $today=number_format(str_replace(' kWh','',$dom['CounterToday']),3);
        $sumtoday=$sumtoday+$today;
    }
}
Udevice(516,0,$sumusage.';'.$sumtoday);

function Udevice($idx,$nvalue,$svalue){
    echo file_get_contents('http://127.0.0.1:8080/json.htm?type=command&param=udevice&idx='.$idx.'&nvalue='.$nvalue.'&svalue='.$svalue);
}
Place the devices that you want a total of in a roomplan.
Adjust the roomplan (and ip:port) in de $domoticz= line
Adjust the idx in the Udevice call.
Execute the script every minute (or every x seconds) from cron.

If you like to be adventurous and start with my Pass2php script you wouldn't need cron for this and could have a total in realtime.

Thank You but something not working.

Thats what I change

Everything seems to work, but my virtual device with the sum, all the time = 0

My roomplan

When I run manualy php script

Code: Select all

root@raspberrypi:~# php  /home/pi/domoticz/scripts/php/energia.php
{
   "status" : "OK",
   "title" : "Update Device"
}
Maybe do I need make some special dummy switch?

Thanks again

Seems you have only 'CounterToday' and no 'Usage'
is this correct?

Yes, that's why I did #

Code: Select all

if($domoticz){
    foreach($domoticz['result'] as $dom){
       # $usage=number_format(str_replace(' Watt','',$dom['Usage']),0);
       # $sumusage=$sumusage+$usage;
        $today=number_format(str_replace(' kWh','',$dom['CounterToday']),3);
        $sumtoday=$sumtoday+$today;

so you will only sending the sum of the 3 Kwh devices to your 'new virtual device' and not Kwh and Watt

maybe I'm also wrong :)
But i learned alot from Egregius his Pass2php script

In my case i got 2 roomplans, first with kWh and second with Watt usage.

only kWh in my case is now:

Code: Select all


<?php
$sumtoday=0;
$domoticz=json_decode(file_get_contents('http://192.168.1.247:8080/json.htm?type=devices&plan=2'),true);
if($domoticz){
    foreach($domoticz['result'] as $dom){
        $today=number_format(str_replace(' kWh','',$dom['CounterToday']),3);
        $sumtoday=$sumtoday+$today;
    }
}
Udevice(372,0,$sumtoday);

function Udevice($idx,$nvalue,$svalue){
    echo file_get_contents('http://192.168.1.247:8080/json.htm?type=command&param=udevice&idx='.$idx.'&nvalue='.$nvalue.'&svalue='.$svalue);
}
Only Watt usage:

Code: Select all


<?php
$sumusage=0;
$domoticz=json_decode(file_get_contents('http://192.168.1.247:8080/json.htm?type=devices&plan=3'),true);
if($domoticz){
    foreach($domoticz['result'] as $dom){
        $usage=number_format(str_replace(' Watt','',$dom['Usage']),0);
        $sumusage=$sumusage+$usage;
    }
}
Udevice(371,0,$sumusage);

function Udevice($idx,$nvalue,$svalue){
    echo file_get_contents('http://192.168.1.247:8080/json.htm?type=command&param=udevice&idx='.$idx.'&nvalue='.$nvalue.'&svalue='.$svalue);
}
First script work i think correctly (i must check this more carefully) but second with Watt only i have error

replace:

with:

$usage=number_format(str_replace(' Watt','',$dom['Data']),0);
and try again ;)

kWh count not sum data correctly

Code: Select all

  $today=number_format(str_replace(' kWh','',$dom['CounterToday']),3);
What mean 3 on the end this line ?

lg function not work for me:
after add lg('$today: '.$today);

Code: Select all

pi@raspberrypi:~ $ php /home/pi/domoticz/scripts/php/energia.php
PHP Fatal error:  Call to undefined function lg() in /home/pi/domoticz/scripts/php/energia.php on line 7

lg is a function of pass2php to log a message in the Domoticz log:

Code: Select all

function lg($msg){file_get_contents('http://192.168.2.2:8080/json.htm?type=command&param=addlogmessage&message='.urlencode('=> '.$msg));}
The 3 at the end is a parameter of the number_format function defining the number of decimals. 1.23456789 becomes 1.235 with that.

I think that when you add both watt and kWh devices in one roomplan it must be possible to also make a sum of the kWh.
You could then post both numbers to one dummy device.

Ok, before i go forward i need run pass2PHP

Edit: tempolary moved to pass2PHP viewtopic.php?f=64&t=12343&p=131489#p131489

It's not required to use pass2php for this. But once you start with php you can't stop :P
For pass2php questions: viewtopic.php?f=64&t=12343

For this, you could just add the lg function to your script.

Nice script. Yesterday I was very happy with it. Now it seems the script cannot add up if the individual values exceed 1000. Any thoughts on this?
