[Sovled] ShellSwitch - Pimatic will not post the Error from the Script

---

Hey Guys,

made this little script with snippets that i found. In the comandline works the script fine if there is a Error, but as ShellSwitch pimatic will just say “timeout” or Pimatic is just switching it in without any trouble.

Here the Script:

#!/usr/bin/php

<?php
if(empty($argv[1]) or empty($argv[2])){
        die("Arguments missing.");
}

// build URL with IP and the Command
// possible commands are for example: CLEAN_START, PAUSE, HOMING

$URL = "http://$argv[1]:6260/json.cgi?%7b%22COMMAND%22:%22$argv[2]%22%7d";

// create a new cURL resource
$ch = curl_init();

// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, $URL);
curl_setopt($ch, CURLOPT_HEADER, 0);

// options for errors
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FAILONERROR, true);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5);

// grab URL and pass it to the browser
curl_exec($ch);

// grab Errors
if(curl_exec($ch) === false)
{
    $error = curl_error($ch);
    die("Error: $error");
    curl_close($ch);
}

// close cURL resource, and free up system resources
curl_close($ch);
?>

I got this snippet form the Fritzbox Script from @Swen in his Script it works fine, i just added a 2nd Value

if(empty($argv[1]) or empty($argv[2])){
        die("Arguments missing.");
}

If i give no Argument in his script i got this Message in Pimatic:

error [pimatic-shell-execute,ShellPresenceSensor]: Error getting attribute value windowsphone-short.presence: undefined
error [pimatic-shell-execute]: [ShellPresenceSensor#windowsphone-short] Error: unknown state="Arguments missing."!

Here my tests in the commandline:

pi@Leetwerkberry:~ $ ./testphp.php

Arguments missing.

pi@Leetwerkberry:~ $ ./testphp.php 192.178.168.60

Arguments missing.

pi@Leetwerkberry:~ $ ./testphp.php 192.178.168.60 START_CLEAN

Error: Connection timed out after 5001 millisecondsp

maybe i found by myself … to get Errors work only with presence sensors?

@tehmilcho You execute START_CLEAN instead of CLEAN_START?

// build URL with IP and the Command
// possible commands are for example: CLEAN_START, PAUSE, HOMING

$URL = "http://$argv[1]:6260/json.cgi?%7b%22COMMAND%22:%22$argv[2]%22%7d";

pi@Leetwerkberry:~ $ ./testphp.php 192.178.168.60 START_CLEAN

Also, i dont know if it is some build-in function of fritzbox but CLEAN_START has no defined function so i assume it is a fritzbox action?

Edit;; Wait im getting confused, did you use a script for a vacuum robot cleaner created @ openhab? If so, CLEAN_START is not defined, it has no action so it would be normal to error out…

What are you trying to do?

Hey

the script is for a lg hombot with wlan hack. My problem is that i want that pimatic shows the errors-messages in the webgui under messages… I check the following stuff:

Have you entered 2 arguments? No output error
Is the HTTP request failed? Yes output error

See in post “my tests in the command line”

@tehmilcho well the script only has an error handler, i dont know php.

// grab Errors
if(curl_exec($ch) === false)
{
    $error = curl_error($ch);
    die("Error: $error");
    curl_close($ch);
}

Maybe you could do a IF false Error Else Continue

Or, idk if it works but try adding this to the bottom after the error handler

// No error, end cURL
if(curl_exec($ch) === true)
{
    curl_close($ch);
}

We had contact on chat, and in the end you want to display the error in the pimatic error list. This is not possible as pimatic cant sort a error or success from a shell sensor.

With a Shell Sensor its working but not with a Shellswitch.

With a Shell Senor you will get this Error if you not entered a Argument.

error [pimatic-shell-execute,ShellPresenceSensor]: Error getting attribute value windowsphone-short.presence: undefined
error [pimatic-shell-execute]: [ShellPresenceSensor#windowsphone-short] **Error: unknown state="Arguments missing."!**
`

@tehmilcho so if the script has two arguments you dont want any output at all?

I got it… i have to use this for errors and not “die”

<?php
fwrite(STDERR, "An error occurred.\n");
exit(1); // A response code other than 0 is a failure
?>

now i get my Errors

error [pimatic-shell-execute]: [ShellSwitch#hombot] Error: Command failed: /bin/sh -c /home/pi/testphp.php 192.168.178.50 START_CLEAN
Failed to connect to 192.168.178.50 port 6260: No route to host

@tehmilcho indead, stderr would be a way, well done.
