+The arest switch platform allows you to toggle pins of your devices (like Arduino boards with a ethernet/wifi connection, the ESP8266, and the Raspberry Pi) running the [aREST](http://arest.io/) RESTful framework.
+
+To use your aREST enabled device in your installation, add the following to your `configuration.yaml` file:
+
+```yaml
+# Example configuration.yaml entry
+switch:
+  platform: arest
+  resource: http://IP_ADDRESS
+  pins:
+    11:
+      name: Fan Office
+    12:
+      name: Light Desk
+```
+
+Configuration variables:
+
+- **resource** (*Required*): IP address and schema of the device that is exposing an aREST API, e.g. http://192.168.1.10.
+- **pins** (*Required*): An array with all used pins of your board.
+  - **name** (*Required*): The name of the variable you wish to monitor.
+
+Accessing one of the endpoints (eg. http://192.168.1.10/analog/2/) will give you a JSON response. The interesting part is `return_value` which represents the sensor's data.
+
+```json
+{"return_value": 34, "id": "sensor02", "name": "livingroom", "connected": true}
+```
