How to extract/show a Entities power "Attribute" as a card on Frontend?

Configuration Frontend

  1. Please format pasted code correctly for the forum. It helps us help you.

  2. Binary sensors only have the states on and off. Power is not a binary_sensor, it is a sensor.

  3. Heed the warning box here: https://www.home-assistant.io/docs/configuration/templating/

  1. You should use the new format for new sensors. Try this:

configuration.yaml

template:
  - sensor:
      - name: "Kogan Plug 06 Power" # or whatever you want to call it
        unit_of_measurement: "W"
        device_class: power
        state_class: measurement # only include this line if you want long term statistics
        state: "{{ state_attr('switch.kogan_smart_plug_06', 'current_consumption') }}"

      - name: "Kogan Plug 07 Power" # or whatever you want to call it
        unit_of_measurement: "W"
        device_class: power
        state_class: measurement # only include this line if you want long term statistics
        state: "{{ state_attr('switch.kogan_smart_plug_07', 'current_consumption') }}"

      - name: etc...

You can then add these entities to any dashboard card. See the right hand column here. History graph or Entities cards would be good choices.
