Greetings everyone, My first post around here. Let me say these message boards are extremely helpful for beginners so thanks to all of you!
I saw someone here is already using 1wire devices to monitor temperature in the 'Fermoire'. I had some hardware laying around and thought it would be useful to keep an eye on the temperature of the area around my carboy as it's pretty darn cold out here in Colorado lately.
WRT54g Linksys Router, Flashed with DD-WRT
Linksys NSLU2, flashed with unraid
1-wire Thermometer from hobby-boards.com
USB converter to attach 1wire device to NSLU2
OWW software on the NSLU2
Also used some scripts that pulled the temperature from the 1wire probe and put it into some RRD (round robin databases) used to trend data, and built a webpage every 5 minutes with graphs and high/low information.
I tend to do little projects like this just to see if it's possible but found this morning it's actually useful! We turned the heater down overnight as it was warming up to almost 40 outside last night and warmed the upstairs a bit. When I woke up to check the status I didn't even have to leave the bed - grabbed my iphone, brought up the webpage, ahhh good consistent temperatures overnight.
I'll post some pictures if wanted but it's nothing special visually - just a few pieces of hardware tucked in a corner hidden as best as possible so the Boss doesn't get angry
