Help debuging

Hi,

When my sonos starts playing, I get a upnp event in the event log. is there a way to get the results codes translated.

When I start the sonos using the alarm (wakeup alarm) I get this:

08 05/20/15 18:53:01.188 JobHandler_LuaUPnP::HandleActionRequest device: 490 service: urn:micasaverde-com:serviceId:Sonos1 action: NotifyRenderingChange <0x30c07680>

The <0x30c07680>, can this be translated, so I can see if the system was powered on by remote or by the wakeup alarm.

I need to see if I can hack this plugin so that I can trigger a sceen when the system powers on due to an alarm event (wakeup light in the morning)
