You can do it without a proxy by adding a snippet of php code.
Here's an example:
<?php
$data = simplexml_load_file('
http://TED5000/api/LiveData.xml'); print ("<tr>");
print (" <td>Solar Generation</td>");
print (" <td><h4>" . $data->Power[0]->MTU2->PowerNow/-1000 . " KW</h4></td>");
print ("</tr>");
print ("<tr>");
print (" <td>Peak Today</td>");
print (" <td><h4>" . $data->Power[0]->MTU2->PeakTdy/-1000 . " KW</h4></td>");
print ("</tr>");
print ("<tr>");
print (" <td>House Consumption</td>");
print (" <td><h4>" . $data->Power[0]->MTU1->PowerNow/1000 . " KW</h4></td>");;
print ("</tr>");
print ("<tr>");
print (" <td>Net Usage</td>");
print (" <td><h4>" . $data->Power[0]->Total->PowerNow/1000 . " KW</h4></td>");
print ("</tr>");
print ("<tr>");
print (" <td>Sample Time</td>");
print (" <td><h4 id=\"sampTime\"></h4></td>");
print ("</tr>");
//get the sample time
print ("<script type=\"text/javascript\">");
print (" var h=" . $data->GatewayTime[0]->Hour . ";");
print (" var m=" . $data->GatewayTime[0]->Minute . ";");
print (" var s=" . $data->GatewayTime[0]->Second . ";");
?>
There are a couple of prerequisites - this has to be served by a server that supports php, and you need to name your source xxx.php, not xxx.html.
