Add this to your configuration.yaml file:

template:
  - sensor:
      - name: "Kelvins PC Available Space"
        unit_of_measurement: "%"
        state: "{{ state_attr('sensor.kelvinspc_storage_c', 'AvailableSpacePercentage') }}"

Then do a yaml reload, or restart home assistant.

Worked perfectly, thank so much, over a period of 3 days I reckon I spent
5 hour trying to figure it out.
There should be a repository for templates.
