---Vera
1. Installed AD2USB plugin (It creates 2 devices, one for Panel, one for Partition)
2. Uploaded latest, patched L_VistaAlarmPanel1.lua from this thread
3. On the Panel device add the overNetwork setting in UI7 manually:
Panel device > Advanced ... New Service/Variable
New Service: urn:micasaverde-com:serviceId:VistaAlarmPanel1
New Variable: overNetwork
New value: 1
4. On the Panel device change the 'ip' variable to the ser2net ip:port from your raspberry pi
5. On the Partition device set the KeypadAddresses to 31(yours may be different)
