Machine status from domoticz Leave a reply

Posted on April 8, 2017 in home automation, linux, raspberryPi

This is how I solved it!

The script that show status on homepage.

<?php
echo "<b>Machine status</b>";
echo "</br>";
$arr = array(5, 7, 9);
foreach ($arr as &$value) {
 
$get_data = "http://10.0.20.11/json.htm?type=command&param=getuservariable&idx=".$value;
$result = file_get_contents($get_data);
$decode = json_decode($result,true);
 
	if ($decode["result"][0]["Value"] == "1"){
 
	$icon = "green-icon.png";
	}
	else {
	$icon = "red-icon.png";
	}
 
switch ($decode['result'][0]['Name']) {
    case "washingmachine_status":
        $unit = "Washing machine";
        break;
    case "dryer_status":
        $unit = "Dryer";
        break;
    case "dishwasher_status":
        $unit = "Dishwasher";
        break;
}
 
 
 
	echo "</br>     " . $unit . "</br><img src=\"/wp-content/uploads/2015/12/" . $icon . "\"><em>" . $decode['result'][0]['LastUpdate'] . "</em><br>";
 
}
?>

The script that check my machines.

--script_time_washingmachine.lua
--This script monitors the current consumption indicated by a Z-Wave plug, placed between the washingmachine and the mains outlet
--It will count the amount of time that the power usage is below the triggervalue to be configured below. This indicates us that the washer has finished.
