Yaml code for battery in energy dashboard

Energy

1

Hi all, i have a sensor called : sensor.victron_system_battery_power telling me if battery is charging or discharging. This is only 1 figure. The energy dashboard ask for 2 figures (battery in and battery out). How to create this via a template?
so when sensor shows -1.250W, it means battery is discharging. So i would need the following in my energy dashboard: battery in:0 & battery out: -1.250W.

Can someone help me on this?
Many thanks!

configuration.yaml

template:
  - sensor:  
      - name: Battery Power In
        unit_of_measurement: W
        device_class: power
        state_class: measurement
        state: >
          {% if states('sensor.victron_system_battery_power') | float > 0 %}
            {{ states('sensor.victron_system_battery_power') }}
          {% else %}
            0
          {% endif %}
        availability: "{{ has_value('sensor.victron_system_battery_power') }}"

      - name: Battery Power Out
        unit_of_measurement: W
        device_class: power
        state_class: measurement
        state: >
          {% if states('sensor.victron_system_battery_power') | float < 0 %}
            {{ states('sensor.victron_system_battery_power') |float | abs }}
          {% else %}
            0
          {% endif %}
        availability: "{{ has_value('sensor.victron_system_battery_power') }}"

Note: To be used in the energy dashboard you will need energy sensors, not power sensors.

So you will have to feed both sensor.battery_power_in and sensor.battery_power_out into the Riemann Sum Integral helper to convert power to energy. Make sure to use method: left to minimise approximation errors.

You can then use these two energy sensors in your energy dashboard.
