The arest switch platform allows you to toggle pins of your devices (like Arduino boards with a ethernet/wifi connection, ESP8266 based devices, 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:

# Example configuration.yaml entry
switch:
  platform: arest
  resource: http://IP_ADDRESS
  name: Office
  pins:
    11:
      name: Fan
    12:
      name: Light Desk

Configuration variables:

• resource (Required): IP address and schema of the device that is exposing an aREST API, eg. http://192.168.1.10.
• name (Optional): Let you overwrite the the name of the device. By default name from the device is used.
• 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.

{"return_value": 34, "id": "sensor02", "name": "livingroom", "connected": true}
