Hi TR,
I am afraid, IOT is not supported on ZD platform and to use IoT capability, AP's need to be pushed with IOT firmware which is only possible with v/SZ. The main challenge behind not supporting IoT with ZD platform is Ruckus is moving away from ZD platform and ZD1200 is the last product in the ZD family. Small and medium customer environments are transitioning to unleashed or cloud platforms and large scale enterprise customers are moving to v/SZ. However, engineering completely understand the request and they are looking at options to support IoT for residential / smart home owners.
