title: "Adding devices to Home Assistant"
description: "Steps to help you get your devices in Home Assistant."
---
Home Assistant will be able to automatically discover many devices and services available on your network if you have [the discovery component](/integrations/discovery/) enabled (the default setting).
See the [integrations overview page](/integrations/) 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/).
Classification for the available integrations:
- [IoT class](/blog/2016/02/12/classifying-the-internet-of-things): Classifier for the device's behavior.
- [Quality scale](/docs/quality_scale/): Representation of the integration's quality.
Usually every entity needs its own entry in the `configuration.yaml` file. There are two styles for multiple entries:
## 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"
name: "Weather"
switch:
- platform: vera
```
## 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
sensor bedroom:
platform: mqtt
state_topic: "home/bedroom/temperature"
name: "MQTT Sensor 1"
sensor kitchen:
platform: mqtt
state_topic: "home/kitchen/temperature"
name: "MQTT Sensor 2"
sensor weather:
platform: rest
resource: "http://IP_ADDRESS/ENDPOINT"
name: "Weather"
switch 1:
platform: vera
switch 2:
platform: vera
```
## 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 {% my developer_states title="States page in the Developer Tools" %}.
```yaml
# Example configuration.yaml entry
group:
living_room:
entities:
- light.table_lamp
- switch.ac
bedroom:
entities:
- light.bedroom
- media_player.nexus_player
```
For more details please check the [Group](/integrations/group/) page.
