Notes

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

If you have enabled “Device tree support” (since Raspbian with kernel 3.18 it's the default configuration), you have to add the following line to /boot/config.txt:

dtoverlay=w1-gpio-pullup,gpiopin=4

This will load the module w1-gpio, so you only have to add w1-therm to your /etc/modules.

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 28- as the correct id, e.g. 0000055bd776.
