I’ve written a simple library to manage remote access to Vera devices running UI6/UI7.
There’s not much to it, it just takes care of getting all the session keys and stuff, so you can use the regular Luup requests from http://wiki.micasaverde.com/index.php/Luup_Requests.
The process is based on the excellent notes at http://forum.micasaverde.com/index.php/topic,24942.0.html.
Best,
Wade
