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 pin you wish to toggle.
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}
```
