Can't add API data from template to Energi Solar or power calculation

Hello,

I have my rest sensors from template:

    solax_api_yieldtoday:
      friendly_name: "Solax AC energy out daily"
      value_template: "{{ state_attr('sensor.solax_api', 'yieldtoday') | float(0) }}"
      availability_template: "{{ state_attr('sensor.solax_api', 'yieldtoday') | is_number }}"
      unit_of_measurement: "kWh"
      device_class: energy
      icon_template: mdi:solar-power-variant-outline
    solax_api_yieldtotal:
      friendly_name: "Solax AC energy out total"
      value_template: "{{ state_attr('sensor.solax_api', 'yieldtotal') | float(0) }}"
      availability_template: "{{ state_attr('sensor.solax_api', 'yieldtotal') | is_number }}"
      unit_of_measurement: "kWh"
      device_class: energy
      icon_template: mdi:solar-power-variant-outline

How I can use those into Energy consumption in home assistant? I tried to add:

#      state_class: total_increasing
#      last_reset: '1970-01-01T00:00:00+00:00'

But then I receive error.
