I removed the comment from the code you posted and modified for my needs.
Almost perfect!
Here it is:
// Example how to add a fixed menu item:
$menu['right'][] = array(
'name'=>'Home',
'icon'=>'icon-home icon-white',
'path'=>"redirect_home.php",
'session'=>"write",
'order' => 60,
'divider' => true);
The only problem is that the default path is already 192.168.4.2/emoncms.
So I added a redirect.php in emoncms folder pointing at 192.168.4.2/home.
