The problem I'm having is that I can't connect to both at the same time. My older Prime connects via Wi-Fi but for some reason I can't connect to the new one with Wi-Fi. I can only connect to it using Bluetooth. My phone won't allow me to do both at the same time. (Turning on Bluetooth disables the Wi-Fi connection).In the app, when you click in light- you will see option to parent and enter serial number, etc
