The device and concept are great, and makes my Summit Grill Center a smart grill.  I got this a a gift, and I also have a SmokeFire with three built in hub.  The problem is that the App only allows for one Hub.... either my SmokeFire or the Connect hub.  Each time I use one grill or the other,  I have to forget the other device and re-pair the hub.  Weber has no plan for the app to support pairing data from more than one device.
