Using Domoticz with Eastron SDM 220

videodrome · Post by **videodrome** » Thursday 11 August 2016 18:20

I need a help to edit a php script
The script below, reads from a meter (eastron sdm 220 c) under rs485 modbus.
I can't import the reading of the imported energy from the grid. (-i) on this php script for eastron. All the readings works well.
I entered in line n. 5 -i for reading, but this seems not to work.

Code: Select all

#!/usr/bin/php

@Egregius (thanx for previous solar script): i try using your script, but this seems not to work at all, what's wrong?
Maybe I forgot to enter some parameters?

Code: Select all

if ($data[8] = 'OK') {
  $tensione = udevice(1,0,$data[0]);
  $corrente = udevice(2,0,$data[1]);
  $potenza = $data[2];
  $cosfi = udevice(4,0,$data[3]);
  //$frequenza_2 = $data[4];
  $immessa = udevice(43,0,$data[5]);
  $prelevata = udevice(44,0,$data[6]);
  $energia = udevice(3,0,$data[7]);

function udevice($idx,$nvalue,$svalue) {

can you add a 'echo $x;' line after x=...
and a 'print_r($data);' after $data=...

The script for the Fronius is working now?
If you can get the data of the Eastron in variable $x we'll get it in domoticz.

A tip while programming in PHP:
add many echo's for your variables. If the output of echo is just 'array()' you need to use print_r($variable) to show it. Also adding <hr> to it helps finding what's outputted from where. The html tag <pre> shows the array in a nice way.

So for your peace of code:

Code: Select all

#!/usr/bin/php
<?php
$data = array();
inizio:
$x = exec("/usr/local/bin/sdm120c -v -c -p -g -f -e -i -t -q -w3 -z5 /dev/ttyUSB0");
echo 'x = '.$x.'<hr>';
$data = preg_split('/[[:space:]]+/', $x);
echo 'data = <pre>';print_r($data);echo '</pre><hr>';
if ($data[8] = 'OK') {
    echo 'data 8 ok<hr>'.$data[0].'-'.$data[1].'-'.$data[2].'-'.$data[3].'-'.$data[4].'-'.$data[5].'-'.$data[6].'-'.$data[7];
  $tensione = udevice(1,0,$data[0]);
  $corrente = udevice(2,0,$data[1]);
  $potenza = $data[2];
  $cosfi = udevice(4,0,$data[3]);
  //$frequenza_2 = $data[4];
  $immessa = udevice(43,0,$data[5]);
  $prelevata = udevice(44,0,$data[6]);
  $energia = udevice(3,0,$data[7]);
}

sleep(2);
goto inizio;

function udevice($idx,$nvalue,$svalue) {
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, "http://192.168.0.10:8080/json.htm?type=command&param=udevice&idx=$idx&nvalue=$nvalue&svalue=$svalue");
    curl_exec($ch);
    curl_close($ch);
}

There's also no need to mask the ip address as it is an internal IP. Nobody can do anything with it.
A script like this should be run from command line. Because of the sleep and loop a browser would never show the output.

Yes the solar script works well.
And i I took your advice by increasing the sleep in the script (eastron) to 30 seconds. Looking at the log there were too many redundant and close readings. Now is much better.
When at home, I edit the script of the Eastron and I'll tell you.

Or use var_dump

There's no error in line 6.

try it with doubl quotes

I don't know what to say. The code is good, tested it.
If I don't know the value of x I can't help you putting it in an array.

I'm a totally newbie of php
but if you ask me the output of x (Eastron) is:
230.68 4.86 1055.34 0.94 50.02 1228547 794604 2023151 OK

where the outputs are:
voltage - current (A) - active power - power factor - frequency - exported power (Wh) - imported power (Wh)- total power (Wh)

Well, if I use that as x it works fine for me:

Code: Select all

#!/usr/bin/php
<?php
$data = array();
inizio:
$x = "230.68 4.86 1055.34 0.94 50.02 1228547 794604 2023151 OK";
echo '<hr>x = '.$x.'<hr>';
$data = preg_split('/[[:space:]]+/', $x);
echo 'data = <pre>';print_r($data);echo '</pre><hr>';
if ($data[8] = 'OK') {
    echo 'data 8 ok<hr>'.$data[0].'-'.$data[1].'-'.$data[2].'-'.$data[3].'-'.$data[4].'-'.$data[5].'-'.$data[6].'-'.$data[7].'<hr>';
  $tensione = udevice(1,0,$data[0]);
  $corrente = udevice(2,0,$data[1]);
  $potenza = $data[2];
  $cosfi = udevice(4,0,$data[3]);
  //$frequenza_2 = $data[4];
  $immessa = udevice(43,0,$data[5]);
  $prelevata = udevice(44,0,$data[6]);
  $energia = udevice(3,0,$data[7]);
}

//sleep(2);
//goto inizio;

function udevice($idx,$nvalue,$svalue) {
    echo $idx.' '.$nvalue.' '.$svalue.'<br/>';
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, "http://192.168.0.10:8080/json.htm?type=command&param=udevice&idx=$idx&nvalue=$nvalue&svalue=$svalue");
    curl_exec($ch);
    curl_close($ch);
}

gives this output:
#!/usr/bin/php

x = 230.68 4.86 1055.34 0.94 50.02 1228547 794604 2023151 OK

What version of PHP are you running? Maybe something with that. I use 5.6.

I understand .... for some strange reason the output of the counter reverses the 2 readings of exported and imported energy.... from the command line I run "sdm120c -v -c -p -g -f -e -i -t -q -z5 /dev/ttyUSB0" and the replay was 230.68 4.86 1055.34 0.94 50.02 1228547 794604 2023151, but the correct reading should have been 794604 1228547 ( I noticed it reading the real output from the Eastron's display).
I changed my first script as below and now everything works well.

one last thing ... is it possible to add in this script another sensor that calculates the autoconsumption (ie total energy generated by the PV, sensor from solar.php) + imported energy (sensor n.72) - exported energy (sensor n.69)?

You should use a function for the udevice command. Code will be lots smaller and better readable.
You could also combine the two scripts into one.

Where do I enter in the script the reference to the total energy sensor (sensor n. 57, sensor name "Energia tot. prodotta Pv Fronius")?

Egregius · Post by **Egregius** » Friday 19 August 2016 23:47

Did you look at the code or just copy/paste it? Have you seen the 'Calculate the total' line?

Yes but, correct me if I'm wrong, the value of "$prelevata1" in the line "calculate the total" does not match with the value of energy produced from my photovoltaic. This value (on Kwh) is from another sensor (below) from solar.php script.

Egregius · Post by **Egregius** » Saturday 20 August 2016 1:24

then combine the script into the solar.php script?

I don't know. What's in solar.php? What does it do?
And do you really need all that data every 30 seconds? For what purpose?
I'm always trying to limit the calls to Domoticz to keep it as fast as possible.

videodrome · Post by **videodrome** » Saturday 20 August 2016 19:19

solar.php reads the production of photovoltaic system. 3 sensors, 58, 59 and 60 give me the output of power, day and total energy of inverter.
In the function totalenergy to calculate the auto consumption I should replace the value of $prelevata1 with the value of sensor 58 (day energy).

//Calculate the total
$totalenergy = $prelevata1 + $prelevata2 - $immessa;
udevice(123,0,$totalenergy);

Code: Select all
