Temperature control in my grill has been an issue for me for a while so I thought it would be helpful to get a remote temperature sensor system. The Weber Connect Smart Grilling Hub gives you two temperature probes, one for your meat and one for the ambient temperature in the grill.  It all connects to an app that you download for either iOS or Android.  I had no issues with syncing everything up and the system works as advertised.  The app is pretty basic in it's current configuration and I would like to see more features added, especially around multiple alerts being allowed.
