Utility Meter - Last Period State Addition

Feature Requests
1

To use the Utility Meter I had to add this template sensor to record only the hourly energy consumption:

    sensors:
      util_meter:
        friendly_name: 'Hourly Utility Meter'
        unit_of_measurement: 'kWh'
        value_template: '{{ states.sensor.furnace_hourly.attributes.last_period | float }}'

Configuration code:

  furnace_hourly:
    source: sensor.sensor_furnace_power_integral
    cycle: hourly

I removed states.sensor.furnace_hourly and sensor.sensor_furnace_power_integral from my recorder because I don’t want to fill up the database with intermediate calculation data.

While I have a workaround, it would be more convenient for users to have a “Last Period” state instead of or in addition to an attribute.
