I can verify that CentraLite 4256050-RZHAC lamp module can be added to the Zigbee network. It wasn’t one of the lamp modules listed when adding it, but when adding generic zigbee devices, it add just fine. This is a plug module that Time Warner Cable uses in their Intelligent Home Zigbee network. I am a field tech so I was very excited to see that Vera was adding zigbee. Ill be testing some other devices(door sensors, thermostats…) that TWC uses and will report my findings to you guys.
