Hi Wes,
UDI is adding support all the time for new Z-Wave devices. A lot of these devices reports multiple device information such as a sensor ON/OFF status along with battery level. I'm thinking specifically of the Aeon MultiSensor which has two nodes. One reports motion on/off and battery level and the other reports Temperature, Humidity and Lumins (lux). It's really a pain to open up the Admin Console on the ISY to see these values. Hopefully you're working on a solution for these type of devices?
