You just don't have to use it. I have a Maverick thermometer I monitor grill and meat temps with. If the grate temp is running 10 degrees hotter than what you want, then crank the controller down 10 degrees for example. Or you can adjust it with the app. You connect your phone straight to the pit and don't have to go through the house WiFi to use the app when cooking, but you have to connect the pit through the app to the house to update the firmware. It's been a while since I did it but the instructions were clear enough I was able to do it. And I'm far from being good with stuff like that.
