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).
Usually every entity needs its own entry in the
configuration.yaml file. There are two styles for multiple entries:
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
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
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: light.table_lamp, switch.ac bedroom: - light.bedroom - media_player.nexus_player
