@ -17,7 +17,7 @@ There are different ways for communication between add-ons inside Hass.io.
We use an internal network that allows to communicate with every add-on, even to/from Home Assistant, by using its name or alias. Only the add-ons which run on the host network are a bit limited. These can talk with all internal add-ons by their name but all other add-on can't address these add-on by name - using an alias works for both!
Name/alias are used for communication inside Hass.io.
The name is generated using the following format: `{REPO}_{SLUG}`, e.g., `local_xy` or `3283fh_myaddon`. In this example, `{SLUG}` is defined in an add-ons `config.json`. If an add-on is installed locally, `{REPO}` will be `local`. If the add-on is installed from a Github repository, `{REPO}` is a hashed identifier generated from the GitHub repository's URL (ex: https://github.com/xy/my_hassio_addons). See [here](https://github.com/home-assistant/hassio/blob/587047f9d648b8491dc8eef17dc6777f81938bfd/hassio/addons/utils.py#L17) to understand how this identifier is generated. Note that this identifier is required in certain service calls that use the [Hass.io add-on API](hassio-addon-api). You can view the repository identifiers for all currently installed add-ons via a GET request to the hassio API `addons` endpoint.
The name is generated using the following format: `{REPO}_{SLUG}`, e.g., `local_xy` or `3283fh_myaddon`. In this example, `{SLUG}` is defined in an add-ons `config.json`. You can use this name also as DNS name but you need replace the `_` with `-` to have a valid hostname. If an add-on is installed locally, `{REPO}` will be `local`. If the add-on is installed from a Github repository, `{REPO}` is a hashed identifier generated from the GitHub repository's URL (ex: https://github.com/xy/my_hassio_addons).

Use `hassio` for communication with the internal API.
