## About

This add-on allows you to manage and program your ESP8266 and ESP32 based microcontrollers
directly through Hass.io **with no programming experience required**. All you need to do
is write YAML configuration files; the rest (over-the-air updates, compiling) is all
handled by ESPHome.

[_View the ESPHome documentation here_](https://esphome.io/)

## Example

With ESPHome, you can go from a few lines of YAML straight to a custom-made
firmware. For example, to include a [DHT22][dht22].
temperature and humidity sensor, you just need to include 8 lines of YAML
in your configuration file:

Then just click UPLOAD and the sensor will magically appear in Home Assistant:

## 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.

**NOTE**: Installation on RPis running in 64-bit mode is currently not possible. Please use the 32-bit variant of HassOS instead.

## Configuration

**Note**: _Remember to restart the add-on when the configuration is changed._

Example add-on configuration:

```json
{
  "ssl": false,
  "certfile": "fullchain.pem",
  "keyfile": "privkey.pem",
  "port": 6052
}
```

### Option: `port`

The port to start the dashboard server on. Default is 6052.

### Option: `ssl`

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.
