Fatal error:  Uncaught Error: Call to undefined function hg_invoke() in /var/lib/homegear/www/rpc/index.php:52
Stack trace:
#0 {main}
  thrown in /var/lib/homegear/www/rpc/index.php on line 52

Hab das Script gerade mal auf die das Homegear Objekt umgeschrieben (quick hack):

Allerdings bringt das homegear komplett zum Absturz:

root@homegearpi:/var/lib/homegear/www/rpc# ps aux | grep homegear
homegear 12208  4.8  4.5 432816 43584 ?        TLsl 01:01   0:05 /usr/bin/homegear -u homegear -g homegear -p /var/run/homegear/homegear.pid

root     12524  0.0  0.2   5888  1900 pts/1    S+   01:03   0:00 grep homegear

listFamilies funktioniert noch, bei listDevices steigt er aus.

Hey @pmayer,

Da hat sich ein Fehler in “listDevices” im letzten Nightly eingeschlichen. Im aktuellen (Versionsnummer ist gleichgeblieben) ist dieser korrigiert.

Die “hg_”-Funktionen habe ich mal entfernt, daher ging es nicht mehr. Ich hatte vergessen, dass ich diese noch im Webinterface verwendet hatte… Deine Änderungen baue ich gleich mal ein.

Viele Grüße

Sathya

Hab die index.php dann doch noch mal aufgeräumt und ein wenig error handling eingeführt:

<?php

$hgDevices = [];
$hgVersion = '-';
$hgError = false;

try {

    $hg = new \Homegear\Homegear();

    $hgVersion = explode(' ', $hg->getVersion())[1];

    $families = $hg->listFamilies();

    $familyNames = [];
    foreach ($families as $value) {
        $familyNames[$value["ID"]] = $value["NAME"];
    }

    $rawDevices = $hg->listDevices(false, ["FAMILY", "ID", "ADDRESS", "TYPE", "FIRMWARE"]);

    foreach ($rawDevices as $item) {

        $info = $hg->getDeviceInfo($item["ID"], ["NAME", "INTERFACE"]);

        $hgDevices[] = [
            'name' => $info["NAME"],
            'family' => $familyNames[$item["FAMILY"]],
            'id' => ($item["ID"] > 999999 ? "0x" . dechex($item["ID"]) : $item["ID"]),
            'address' => $item["ADDRESS"],
            'type' => $item["TYPE"],
            'interface' => (array_key_exists("INTERFACE", $info) ? $info["INTERFACE"] : "&nbsp;"),
            'firmware' => $item["FIRMWARE"]
        ];
    }


} catch (\Exception $e) {
    $hgError = $e->getMessage();
}
