Setup One Wire projects on Rasperry Pi

These are some notes on how to setup various of my developments regarding OWFS on a Raspberry Pi.

Install required packages.

apt-get install fcgiwrap
apt-get install ferm lzma nullmailer vim unattended-upgrades #for convenience

• Download phpliteadmin from https://code.google.com/p/phpliteadmin/
  • In phplieadmin's configuration file set $directory = '/var/lib/owst/'
• Create sqlite3 database as well as log and lock file and set permissions
• Insert into the databases' table switch the One-Write Switch you want to control
  • ow_type e.g. DS2413
  • ow_address e.g. 3A.B36249000000
  • ow_pio e.g. PIO.B

• test with 1wgetValues.pl
• run 1wSensorMon.pl, you get an error that the rrd-file cannot be opened, but that's OK, check /srv/1wMonitoring/sensors.txt
• execute libexec/gen_rrd_create.pl - run the output as a command
• execute 1wSensorMon.pl - no error this time
• activate cron job
