no, there is NO PROBLEM

Describe the solution you'd like

Today, datasets entities provide both: used and available values, but there is no usage in %. It would be very valuable to have such sensor or even attribute without a need of creating it in Home Assistant.
Today, with this super nice integration, to see in HA the usage in % and i.e. act on it if its value is above the defined threshold, I need to:
1- create sensor in HA (template) and calulate it, i.e:

• platform: template
  sensors:
  truenas_pool_usage:
  friendly_name: "Truenas pool usage"
  unique_id: truenas_pool_usage
  unit_of_measurement: "%"
  value_template: "{{ (100 * state_attr('sensor.truenas_datasets_pool', 'Used') / (state_attr('sensor.truenas_datasets_pool', 'Used') + state_attr('sensor.truenas_datasets_pool', 'Available'))) |float|round(1) }}"

2- use the new sensor called: "truenas_pool_usage" in lovelace, i.e.:

3- use the new sensor called: "truenas_pool_usage" in automations to i.e. send the message: "pool usage too high" or so
