I have searched the interweb high and low but alas I have not been able to find a Wi-Fi digital thermometer. I know it sounds like a crazy and trivial option. For me to go off site to be able to monitor my smoker temps a few miles away from work while catching a few zzz's or running errands its convenience has saved my butt more than a few times. Especially being able to monitor from my phone, laptop, or desktop. I can roll over in the middle of the night in bed and check my phone and be able to tell at a glance that the smoker hasn't dropped temp or that my pork butts are not overcooked.
It may not be the prettiest setup but it works!

2) Q-See Network Surveillance System
3) IPCam Viewer app available for Android and iOS
I hope that one day someone will release a thermometer that actually can connect to a wireless network and post thermal readouts to a static IP Address. Being able to monitor from anywhere in the world without having to point a camera at my receiver would be awesome! Also if anyone happens to know if such a device already exists I would love to know!
