It exists diferent ways to communication between add-ons or home-assistant inside Home-Assistant.
{% linkable_title Network %}
We use a internal network. That allow to speak with every add-on or from Home-Assistant to add-on by name or alias. Only the a add-on they run on Host network are a bit limited. They can speak with all internal add-ons over there name but all other add-on can't speak with the add-on name to this add-on, but alias work wheel. So use the name/alias to communicate inside Hass.io
i.e. use hassio to speak with internal API.
{% linkable_title Home-Assistant %}
A Add-on can speak to Home-Assistant API with our internal proxy. That make it very easy to speak to this API without you need know the password, port or any other information for the Home-Assistant instance. Use this url: http://hassio/homeassistant/api and they will internal redirected to the right place. As next add homeassistant_api: true to config.json.
It is also possible to speak direct to Home-Assistant instance with name homeassistant over our internal Network. But you need know the running config.
We have severals services for Hass.io inside Home-Assistant to execute some task. So you can also use hassio.addon_stdin to send data over STDIN to a add-on.
{% linkable_title Hass.io API %}
To call to our Hass.io API add hassio_api: true to config.json. Now you can use the API over this url: http://hassio/.
