 Hass.io is a managed environment, which means that you can't install applications that can be embedded into Home Assistant using the `command_line` sensor/switch.

+There are three options if you need to run a script to read data from a sensor or send commands to other devices on Hass.io.
 
 The first option is to write a custom component for Home Assistant. Using Python, you can communicate with your device. For more information about developing a custom component, take a  look at the [developer documentation][custom-component].
 
-The second option is to make a local add-on for Hass.io that sends the data to Home Assistant via MQTT. Before we dive into this, read up on [Hass.io add-on development][addons-tutorial] first.
+The second option is to use STDIN inside add-on and use the service `hassio.addon_stdin` to send data. More about this options look into [developer documentation][communication] for internal add-on communication. There is also describe how do you can easy access to Home-Assistant Rest API.
