+# W1-GPIO - One-Wire Interface
+
+To enable the one-wire interface you need to add the following line to /boot/config.txt, beofre rebooting your Pi:
+
+```
+dtoverlay=w1-gpio
+```
+
+Alternatively you can enable the one-wire interface on demand using:
+
+```
+sudo modprobe w1-gpio
+```
+
+once either of the steps above has been performed, you can list the devices your Raspberry Pi can probe via (by default) GPIO4, like so:
+
+```
+ls /sys/bus/w1/devices/
+```
