Battery with a different sensor for charge and discharge

[SNAPE15]

Is it possible to use 2 sensors for the battery flow, 1 showing charge and 1 showing discharge? As my inverter doesnt give a single sensor with negative and positive values.
Love the card, slowly working out how to use it with a Sungrow Inverter.

Hi. You need to create a template sensor that does this. I think it may have been asked here before but if not you can also find examples on the HA forum. Something like the below

sensor:
  - platform: template
    sensors:
      battery_power_combined:
        friendly_name: "Battery Power Combined"
        unit_of_measurement: "W"
        device_class: "Power"
        value_template: >-
          {% set charge_power = states('sensor.battery_charge_power') | float %}
          {% set discharge_power = states('sensor.battery_discharge_power') | float %}
          {% if charge_power > 0 %}
            {{ -charge_power }}
          {% elif discharge_power > 0 %}
            {{ discharge_power }}
          {% else %}
            0
          {% endif %}

Thanks. That one didnt work for me but i was able to create a helper to perform the task.

Another question if you don't mind?

Is there a way to make the energy_cost_sell figure display even when there is no exporting happening? Currently it only displays when the system is exporting.

The easy way is to use the same sensor (sell cost) for energy_cost_buy

Thank you! Was the easy option.
The best power/energy flow card i've used. Got most of it working very well with my Sungrow Inverter/battery system.
