## Enable One-Wire Interface
One-wire is a single-wire communication bus typically used to connect sensors
to the RaspberryPi. The Raspberry Pi supports one-wire on any GPIO pin, but
the default is GPIO 4. To enable the one-wire interface explicitly set it in
`local.conf`
ENABLE_W1 = "1"
Once discovery is complete you can list the devices that your Raspberry Pi has
discovered via all 1-Wire busses check the interface with this command
`ls /sys/bus/w1/devices/`
