Eq3 eqiva Bluetooth radiator

Hi to all!

many thanks once again for this great support here!
I placed both files eq3.exp & eq3.php in /etc/openhab2/html/, which is accessible via http://[your OH server]:8080/static/[the file name] (see the following link)

And I think the files are correctly accesible via this, meaning that when i try to run this script via the following url= http://XXX.XXX.X.XX:8080/static/bluetooth/eq3.php?mac=XX-XX-X-X-XX-XX&temperature=20
i get the following:

"auto", "OFF" => "manual"); function readShortStatus($mac) { global $script; $cmd = $script . $mac . " devjson"; return shell_exec($cmd); } function setTemperature($mac, $temp) { global $script; $cmd = $script . $mac . " temp " . $temp; return shell_exec($cmd); } function setComforteco($mac, $comfort, $eco) { global $script; $cmd = $script . $mac . " comforteco " . $comfort . " " . $eco; return shell_exec($cmd); } function setMode($mac, $mode) { global $script; $cmd = $script . $mac . " " . $mode; return shell_exec($cmd); } function setBoost($mac, $off) { global $script; $cmd = $script . $mac . " boost"; if ($off) { $cmd .= " off"; } return shell_exec($cmd); } if(strcasecmp($_SERVER['REQUEST_METHOD'], 'POST') == 0){ $request_parameters = $_POST; } else if(strcasecmp($_SERVER['REQUEST_METHOD'], 'GET') == 0) { $request_parameters = $_GET; } $mac = str_replace("-", ":", $request_parameters['mac']); if (isset($request_parameters['temperature'])) { $temperature = str_replace(",", ".", $request_parameters['temperature']); } if (isset($request_parameters['mode'])) { $mode = $request_parameters['mode']; } if (isset($request_parameters['boost'])) { $boost = $request_parameters['boost']; } if (isset($mac)) { if (preg_match($mac_regex, $mac)) { // temperature if (isset($temperature)) { $temperature = floatval($temperature); $result = setTemperature($mac, $temperature); } // mode if (in_array($mode, array_keys($modes))) { $result = setMode($mac, $modes[$mode]); } // boost if (isset($boost)) { if (strcasecmp($boost, "ON") == 0) { $result = setBoost($mac, 0); } if (strcasecmp($boost, "OFF") == 0) { $result = setBoost($mac, 1); } } $response = readShortStatus($mac); } } header('Content-Type: application/json'); echo $response; ?> 

which should be the content of the eq3.php.

i adapted the link to the exp-file, see

but unfortunately, it does not work, meaning that the radiator does not change the temperature to 20°.
any help?
