• different ways to hook these up up to R-Pi
• 1wire USB Adapter from PCSensor.com

I have a couple of these running directly off the GPIO on a pi http://www.adafruit.com/products/374

These are the links I have in my notes but not sure which one/s I ended up using.

• http://www.theturtlepi.com/code/
• http://www.raspberrypi.org/forums/viewtopic.php?t=35508&p=300363

I can share the script when I get home

Also, for some examples of non temperature sensors see

Here is an example I had running for a while https://gist.github.com/chrowe/905a53060ec08882a9bb

Also just ran across http://www.dreamgreenhouse.com/designs/automation/1wire/index.php which seems to have some good concrete suggestions.

I am starting to mess around with this and trying things based on https://github.com/openpipekit/opk-temper1-cli https://github.com/timofurrer/w1thermsensor https://learn.adafruit.com/downloads/pdf/adafruits-raspberry-pi-lesson-11-ds18b20-temperature-sensing.pdf

My work is in https://github.com/chrowe/opk-1-wire-cli

Ok, its basically working. You have to manually add one of the sensor addresses to the pull driver for now.

This could probably be cleaned up but it is now working with both sensor path and temperature scale as arguments
