Setting a value with an automation triggered by another sensor

Configuration
1

I have this automation working but cannot use the value in a utility meter to calculate cumulative usage, do I need to template the value or can it be done within the automation?

alias: Get heat pump power
description: ""
trigger:
  - platform: state
    entity_id:
      - sensor.myenergi_2gm_home_consumption
condition: []
action:
  - variables:
      target_charge: >-
        {{ states('sensor.heatpump_power') | float -
        states('sensor.myenergi_2gm_power_charging') | float }}
  - service: input_number.set_value
    data:
      value: "{{ target_charge }}"
    target:
      entity_id: input_number.daikin_watts
mode: single
2

Why do you says so?

I don’t have it to choose from when I use the helper for utility meter
