## Installation
To install this Hass.io add-on you need to add the ESPHome add-on repository
first:
1. Add the epshomeyaml add-ons repository to your Hass.io instance. You can do this by navigating to the "Add-on Store" tab in the Hass.io panel and then entering https://github.com/esphome/hassio in the "Add new repository by URL" field.
2. Now scroll down and select the "ESPHome" add-on.
3. Press install to download the add-on and unpack it on your machine. This can take some time.
4. Optional: If you're using SSL certificates and want to encrypt your communication to this add-on, please enter `true` into the `ssl` field and set the `fullchain` and `certfile` options accordingly.
5. Start the add-on, check the logs of the add-on to see if everything went well.
6. Click "OPEN WEB UI" to open the ESPHome dashboard. You will be asked for your Home Assistant credentials - ESPHome uses Hass.io's authentication system to log you in.

## Configuration
**Note**: _Remember to restart the add-on when the configuration is changed._
Enables/Disables encrypted SSL (HTTPS) connections to the web server of this add-on.
Set it to `true` to encrypt communications, `false` otherwise.
Please note that if you set this to `true` you must also generate the key and certificate
files for encryption. For example using [Let's Encrypt](https://www.home-assistant.io/addons/lets_encrypt/)
or [Self-signed certificates](https://www.home-assistant.io/docs/ecosystem/certificates/tls_self_signed_certificate/).
### Option: `certfile`
The certificate file to use for SSL. If this file doesn't exist, the add-on start will fail.
**Note**: The file MUST be stored in `/ssl/`, which is the default for Hass.io
### Option: `keyfile`
The private key file to use for SSL. If this file doesn't exist, the add-on start will fail.
**Note**: The file MUST be stored in `/ssl/`, which is the default for Hass.io
### Option: `leave_front_door_open`
Adding this option to the add-on configuration allows you to disable
authentication by setting it to `true`.
### Option: `esphome_version`
Manually override which ESPHome version to use in the addon.
For example to install the latest development version, use `"esphome_version": "dev"`,
or for version 1.10.0: `"esphome_version": "v1.10.0""`.
Please note that this does not always work and is only meant for testing, usually the
ESPHome add-on and dashboard version must match to guarantee a working system.
### Option: `relative_url`
Host the ESPHome dashboard under a relative URL, so that it can be integrated
into existing web proxys like nginx under a relative URl. Defaults to `/`.
### Option: `status_use_ping`
By default the dashboard uses mDNS to check if nodes are online. This does
not work across subnets unless your router supports mDNS forwarding or avahi.
Setting this to `true` will make ESPHome use ICMP ping requests to get the node status. Use this if all nodes always have offline status even when they're connected.
