Forgot to mention - unfortunately with this method, the Elk can't really keep track of status either... that's just inherent to the way the Elk manages scenes - and a giant weakness in my opinion. Lots of the software out there will poll the switches on occassion to figure out when things changed; especially if a known scene was triggered. This is because UPB can't transmit light levels after responding to a scene just because it has no idea how many switches were affected - 1 to 250; and with several, it'd kill the network - so it just doesn't do it at all.
