I looked at that and may have to have one of those. BBQ Guru makes a temp controller / meat thermometer that can be controlled from your phone but I think you have to have wifi at your grill, I think! This works via Bluetooth so that would be great.There is a new I want but haven't met anyone who has it. I want a more thorough review than what I have seen online. It is called an iGrill Thermometer and interfaces with your iProducts from Apple.
Anyone have this yet? Like it? Hate it?
