Send Z-Wave command in script?

[Ben0it]

Hello,

Is it possible to send a Z-Wave command to a device in LUA?

For instance, I would like to change the ring color of a Fibaro wall plug (FGWPE). Using the OpenZWave control panel (as shown in the picture below) I can do this, but using a LUA script, is it possible also?

Don't know about lua, but possible in PHP:

Code: Select all

<?php 
$domoticzurl='http://127.0.0.1:8080/';
$zwaveidx=7;
file_get_contents($domoticzurl.'json.htm?type=openzwavenodes&idx='.$zwaveidx);

function ValuePost($command) {
	global $domoticzurl;
	$zwaveurl=$domoticzurl.'ozwcp/valuepost.html';
	$zwaveoptions = array('http'=>array('header'=>'Content-Type: application/x-www-form-urlencoded\r\n','method'=>'POST','content'=>$command,),);
	$zwavecontext=stream_context_create($zwaveoptions);
	$result=file_get_contents($zwaveurl,false,$zwavecontext);
	return $result;
}

echo ValuePost('85-CONFIGURATION-config-list-1-62=Green illumination');

What to post can be looked up in developer view of your browser. The example above sets the illumination to green of node 85.
The first file_get_contents is just for authentication.

Thanks for the code, I will try it and report about the result here.

Good evening,

Finally, I could find some spare time to play with these commands...it works!

Thanks a lot for the hint.

You're sure the 3th line is still in the code?

Code: Select all

file_get_contents($domoticzurl.'json.htm?type=openzwavenodes&idx='.$zwaveidx);

Without that line the second url fails after some time.

Hi,

Here is my code, I invoque from BASH interpreter with arguments:

Code: Select all

$domoticzURL = 'http://127.0.0.1:8080/';

if (count($argv) != 4)
{
    $command = basename($argv[0]);
    echo "Usage: {$command} node function value\n";
    exit(0);
}

$zwaveNodeID = $argv[1];
$nodeFunction = $argv[2];
$nodeFunctionValue = $argv[3];

function Authenticate($domoticzURL, $zwaveIDX)
{
   $result = json_decode(file_get_contents($domoticzURL.'json.htm?type=openzwavenodes&idx='.$zwaveIDX, false, NULL), true);
   
   if (strtoupper($result['status']) == "OK") 
   {
       return true;
   }
   return $result;
}

function SetNodeValue($domoticzURL, $zwaveNodeID, $functionNumber, $functionValue)
{
    $zwaveURL = $domoticzURL.'ozwcp/valuepost.html';
    $zwaveCommand = "{$zwaveNodeID}-CONFIGURATION-config-list-1-{$functionNumber}={$functionValue}";
    $zwaveOptions = array('http'=>array('header'=>'Content-Type: application/x-www-form-urlencoded\r\n','method'=>'POST','content'=>$zwaveCommand,),);
    $zwaveContext = stream_context_create($zwaveOptions);

    $result = file_get_contents($zwaveURL, false, $zwaveContext);

    if (strtoupper($result) == "OK")
    {
       return true;
    }
    return $result;
}

$result = Authenticate($domoticzURL, $zwaveNodeID);
if ($result != true)
{
    echo "Failed to authenticate: {$result}";
    return 1;
}

$result = SetNodeValue($domoticzURL, $zwaveNodeID, $nodeFunction, "{$nodeFunctionValue}");
if ($result != true)
{
    echo "Failed to set parameter: {$result}";
    return 2;
}

return 0;

Invocation from shell is performed as follows:

Code: Select all

php -f bin/ozwcmd.php 3 62 "Red illumination"

2016-03-28 - Actually, it seems to fail after a while. Once it fails, if I manually change a parameter from Domoticz' web interface in the OZW control panel, my script works again.

If I look at the PHP code, I would say that one should be able to convert this to a curl command.
I don't know how I should use the PHP code. I don't have the file: 'ozwcp/valuepost.html';

I want to have a simple curl command to switch the alarm sound of the zwave aeotec siren dependend of the situation.

Curl command equivalent:
curl --data "85-CONFIGURATION-config-list-1-62=Green illumination" http://127.0.0.1:8080/ozwcp/valuepost.html

valuepost.html does not exist as webpage, it's a page "inside http Domoticz server"

Hi there,

I was wondering. When invoking the script with nodeID, Function and Value, how does one know the id of the function and the possible values. In the examples the function '62' is called. What is function 62 and what are the other functions?

Hope someone can help.

Thanx in advance.

I have the same question. How did you come up with the "85-CONFIGURATION-config-list-1-62=Green illumination" string? Thanks.
