Adding devices to Home Assistant
Home Assistant will be able to automatically discover many devices and services available on your network if you have the discovery component enabled (the default setting).
See the components overview page to find installation instructions for your devices and services. If you can’t find support for your favorite device or service, consider adding support.
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”
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
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.
media_player livingroom:
platform: mpd
server: IP_ADDRESS
media_player kitchen:
platform: plex
camera 1:
platform: generic
camera 2:
platform: mjpeg
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 ().
# Example configuration.yaml entry showing two styles
group:
living_room:
entities: light.table_lamp, switch.ac
bedroom:
entities:
- light.bedroom
- media_player.nexus_player
For more details please check the Group page.
