 post-up route add default gw 192.168.2.1 eth0

Set the time zone:

 dpkg-reconfigure tzdata

To re-run the config program run

 sudo raspi-config

... now turn on Interfaces / i2c

Enable OWFS

Follow these directions from SheepWalk Electronics

Install:

 apt-get install i2c-tools owfs ow-shell

If you run this:

 i2cdetect -y 1

you should see an "18" in the grid.

Now, edit /etc/owfs.conf and change

 ... comment out server: FAKE = DS18S20,DS2405
 ... and add server: device=/dev/i2c-1
 ... and restart with sudo service owserver restart

If you run this:

 owdir

... you should see the bus things and any connected sensors.

Add DataRe User & Cron Job

• adduser datare
• A cron job for "datare"

 4,9,14,19,24,29,34,39,44,49,54,59 * * * * /home/datare/collect ; /home/datare/send

 mkdir /var/spool/datare
 chown datare /var/spool/datare

• Now unpack the agent code into ~datare.
• Check that the files belong to datare.
• Set the time zone or the midnight resets won't get done at the right time
