I don't know about wifi, but I'd like something like that could some how incorporate with your controller and remote. I don't know if that is at all possible, but I thought that I've read somewhere that some American made controllers are able to monitor temps for more than one piece of meat and multiple pits. I would need one for multiple pits as I don't compete and only cook for my family, but from what I've read something like that for competitors would be great and I bet would be worth your time and effort.
