I added the Blazn Wifi controller to my Gridiron a couple of weeks ago, I love it. The ap is kind of cheesy with a slide control to adjust the temp, it is kind of touchy to get the exact temp. It comes as a plug in to the existing controller and an externally mounted antenna. Other than drilling a hole for the antenna it is just a matter of installing the software to get your wifi connected to Roanoake Cloud. I can now control my grill wherever I have wifi or have access to the internet over phone connection.
