I've knocked together a Networked Temperature Controller using the Raspberry Pi, a Teensy 3.0 board, Pi Plate, and 1-wire devices that can be used to remotely monitor and control multiple devices. I plan on using this to monitor and control my beer storage coolers, fermentation chambers, and
brewstand, but it could also be used for other uses such as brooder temperature control for avian breeders, sous vide, etc. You can see the complete write up at my
TeensyPi website. Comments are welcome.
