I have
3 Hobby Board temperature sensors. They are 1 week old.
1 USB 1-wire adaptor, Model: DS9490R-A
1 RJ45 to RJ11 Cable
2 cat 5 cables
Ubuntu Linux 9.04
OWFS 2.7p21
I have the RJ11 in the USB 1-wire, the RJ45 in the first probe, and I daisy chain the other 2 probes with the 2 cat 5 cables.
What works:
After I mount /opt/owfs/bin/owfs -u /var/1-wire/mnt/ I can see the interfaces 10.*
I can query each device and cat stuff like ./settings/units/temperature_scale. ( "C" is what shows up)
I can query each device for temperature like " cat 10.<snip>/temperature" and get a number.
What does not seem to work:
While I get a temperature, it seems to be wrong.
My therostat in this room shows 83 degrees
The temp sensors show between 28.8 - 29.
Goal
I would like to adjust the sensors to the correct temperature.
What is my next step/s ?
