Unable to see any of zigbee devices to the iHub, in ewelink app on my iphone. Everything can be seen on web on pc, but on the app only ewelink wifi smart switches. Well the old zigbee free was able to display any of the connected zigbee devices including the smart zigbee buttons. So in esence if I want to see when a button was clicked or to create scenes using the zigbee button, that is not possible to be done from your phone. To me this is bad, they might advertise CAST but I am not sure if thats worth the money.
