Home Assistant will be able to automatically discover many devices and services available on your network if you have [the discovery component](/components/discovery/) enabled (the default setting).

See the [components overview page](/components/) to find installation instructions for your devices and services. If you can't find support for your favorite device or service, [consider adding support](/developers/add_new_platform/).

Usually every entity needs its own entry in the `configuration.yaml` file. There are two styles for multiple entries:

#### {% linkable_title Style 1: Collect every entity under the "parent" %}

```yaml
sensor:
  - platform: mqtt
    state_topic: "home/bedroom/temperature"
    name: "MQTT Sensor 1"
  - platform: mqtt
    state_topic: "home/kitchen/temperature"
    name: "MQTT Sensor 2"
  - platform: rest
    resource: http://IP_ADDRESS/ENDPOINT

switch:
  - platform: vera
```

#### {% linkable_title Style 2: List each device separately %}

You need to append numbers or strings to differentiate the entries, as in the example below. The appended number or string must be unique.

```yaml
media_player livingroom:
  platform: mpd
  server: IP_ADDRESS

media_player kitchen:
  platform: plex

camera 1:
  platform: generic

camera 2:
  platform: mjpeg
```

### {% linkable_title Grouping devices %}

Once you have several devices set up, it is time to organize them into groups.
Each group consists of a name and a list of entity IDs. Entity IDs can be retrieved from the web interface by using the Set State page in the Developer Tools (<img src='/images/screenshots/developer-tool-states-icon.png' alt='service developer tool icon' class="no-shadow" height="38" />).

```yaml
# Example configuration.yaml entry showing two styles
group:
  living_room: light.table_lamp, switch.ac
  bedroom:
    - light.bedroom
    - media_player.nexus_player
```
