I have two temp probes in my fermentation fridge that are connected to a Raspberry Pi. The RPi pushes data out to a Website/Service called Xively, which lets me poll the data, and build cool graphs. Below you’ll find real-time temperatures for whatever is currently in my fermenting fridge, as well as the fridge temp itself.
