      - light.dining_room

Use Cases:

Control multiple devices together
Create logical groupings
Simplify automations
Improve voice control

Device Templates

Template Sensors from Devices:

# Create calculated sensor
sensor:
  - platform: template
    sensors:
      average_temperature:
        friendly_name: "Average Home Temperature"
        unit_of_measurement: "°F"
        value_template: >
          {{ ((states('sensor.living_room_temp') | float +
               states('sensor.bedroom_temp') | float +
               states('sensor.kitchen_temp') | float) / 3) | round(1) }}
