It is the Tappeque from Innovative solutions LLC. I've had it for close to a year.
1. pretty good accuracy compared to several other top thermometers like the Thermapen. Not as accurate as the Thermapen - but it is within a few degrees and for my don't open the smoker monitor - that is good enough for me.
2. 4 probes - can be assigned to any function - such as chamber, different meats, etc., and you can create your own custom labels for the probes.
3. controlled by an app that you download for free on iOS, Android and Windows mobile devices. I have only used it with my iPhone and iPad and it works fine on those.
4. stores results on the cloud and at the end of the session, can e-mail you a file of all the data so you can see your temp profiles - here is an example the blue line is the chamber - can you tell when I opened the smoker to check on things and when I pushed up the temperature to speed things up?
It comes with a program on your PC or Mac and you have to plug it into the computer to set it up for your WiFi network, set variables, etc. Once you have set it up, you don't have to re-do that unless you change your network.
There is a small box that needs electricity out by the smoker that the probes plug into and which communicates through your WiFi.
The only issue so far is that I have had some connectivity problems if I push the smoker too far from the house and my WiFi router.
I really like being able to see all the temps on my phone from anywhere. I do have a serious warning though. If it looses communication, or the temperature falls outside the range you have set up, it gives you an alarm, which you can disable if you want to.) I learned the hard way to disable it when I am out in a public place like a bar or restaurant. The alarm is:
You get a loud alarm sound, followed by this pretty loud voice saying "Check Your Meat!" I got some pretty strange looks from people in a bar when this happened to me!
