Summation of power consumption of the roller blinds / and lights

Configuration
1

The shutters are integrated via zwave.
The entity for consumption always begins with ‘sensor.rollo*’ and ends with ‘verbrauch_kwh’

I would now like to add up all the values ​​of all roller blinds that have the entity ‘sensor.rollo * consumption_kwh’

My first idea was a template sensor like:

  - platform: template
    sensors:
    verbrauch_rollos_kwh:
    value_template: '{{ states("sensor.rollo*verbrauch_kwh" ) | float }}'
    friendly_name: "Verbrauch Rollos"
    unit_of_measurement: "kWh"

And as a bonus, I would add the consumption of all roller blinds in the energy module to the consumers. Not each blind individually, but summed up as one entity.

The same also applies to the consumption of all lights in the house.
