I signed up for a Kickstarter for a wireless thermometer that connects to your phone, the Meater. In the tradition of such things, it took forEVER to arrive, but once it got here, we've had good luck with it. The only problem is that our WSM is essentially a Faraday cage, which messes with the Bluetooth signal. As long as you're not far from it, it still works fine. And it's pretty amusing to watch the updates on your phone as your meat roasts in the oven... Chouxfly has had a lot of fun with it. (I'll ask him to check in here and post more about his experience.)

So I think the Meater is an extremely cool idea. It is a bluetooth-enabled temperature probe that tracks both the internal temperature and the ambient temperature in the oven, and broadcasts that information to your phone. One of the coolest features for me (as a science nerd) is that the phone retains a record of the data! Here is a cook of a pork tenderloin in our oven a few weeks ago:



The green line is the ambient temperature, while the pink line is the probe temperature. You can see how long it takes for the oven to get up to temperature after opening it to put the tenderloin in, the heating cycles of the range, and when we pulled the tenderloin out of the oven to start resting. The phone app is pretty nice; it has a database of recommended temperatures (as well as what temperatures you want for rare/medium/well done) for most common cuts of meat, and can give you alerts when your food is approaching the target temperature.

My only complaint, as Mamagotcha mentioned, is that our WSM blocks the bluetooth signal pretty effectively, so you can only get readings when you're within about 3 feet of the smoker. This isn't a problem with our oven (which has a glass door), but unfortunately the smoker doesn't work as well. I am going to try putting the app on one of our old smartphones and leaving it next to the smoker as a repeater (the app is smart enough to share information with multiple devices on the same wifi network) but I wish it had the option for a wire antenna that you could run outside the smoker.
