+homeassistant.components.switch.arest
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The arest switch can control the digital pins of a device running with the
+aREST RESTful framework for Arduino, the ESP8266, and the Raspberry Pi.
+Only tested with Arduino boards so far.
+
+Configuration:
+
+To use the arest switch you will need to add something like the following
+to your configuration.yaml file.
+
+sensor:
+  platform: arest
+  resource: http://IP_ADDRESS
+  pins:
+    11:
+      name: Fan Office
+    12:
+      name: Light Desk
+
+Variables:
+
+resource:
+*Required
+IP address of the device that is exposing an aREST API.
+
+pins:
+The number of the digital pin to switch.
+
+These are the variables for the pins array:
+
+name
+*Required
+The name for the pin that will be used in the frontend.
+
+Details for the API: http://arest.io
