Combined energy sensor not available for selection in energy dashboard

Configuration
1

I have 2 solar inverters that each create a sensor by using the Huawei plugin.

I created a manual sensor in configuration.yaml that combines the output of both inverters into a new sensor.

- platform: template
    sensors:
      totalinverterpower:
        friendly_name: "Inverters Input Power"
        device_class: energy
        unit_of_measurement: "kWh"
        value_template: "{{ (states('sensor.inverter_input_power_1') | float) + (states('sensor.inverter_input_power_2') | float) }}"

The sensor is working when I look at it. The problem is that I cannot select this sensor as a solar input in the energy dashboard. I gave it the energy class but that also did not help.

What am I missing here?

Use the template integration for new sensors. Supply default values for your float filters. Include a state_class and an availability template.

configuration.yaml

template:
  - sensor:
      - name: "Inverters Input Power"
        device_class: energy
        state_class: total_increasing
        unit_of_measurement: "kWh"
        state: "{{ states('sensor.inverter_input_power_1') | float(0) + states('sensor.inverter_input_power_2') | float(0) }}"
        availability: "{{ states('sensor.inverter_input_power_1') | is_number and states('sensor.inverter_input_power_2') | is_number }}"

so I should NOT put this under sensors?

what does the total_increasing mean? I dont want to have it added up. I want the current inverter output. Or did I understand this wrong?

If these are power sensors you have the wrong device class and unit of measurement.

template:
  - sensor:
      - name: "Inverters Input Power"
        device_class: power
        state_class: measurement 
        unit_of_measurement: "kW"
        state: "{{ states('sensor.inverter_input_power_1') | float(0) + states('sensor.inverter_input_power_2') | float(0) }}"
        availability: "{{ states('sensor.inverter_input_power_1') | is_number and states('sensor.inverter_input_power_2') | is_number }}"

Power and energy are two different things. You can not use power sensors with the energy dashboard.

And yes, that does not go in your sensors.yaml file.

got it ,thank you
