Note

Before pilight can see the sensor, you have to run the following commands:

sudo modprobe w1-gpio
sudo modprobe w1-therm

To make sure this is done every reboot, edit /etc/modules and add the following lines:

w1-gpio
w1-therm

To find the correct sensor id, you have to run the following commands:

cd /sys/bus/w1/devices
ls

The result will look like:

28-0000055bd776  w1_bus_master1

Use the part after 20- as the correct id, e.g. 0000055bd776.
