Reset sensor data on energie dashboard

Configuration
1

hi all, is it possible to delete all the data from 1 sensor on the energy card? I want to reset the data for the “export to the network” sensor since I am now enabled for export

2

i found this guide for reset data Energy Management in Home Assistant - #455 by markss, but this sensor is not 0, the value is 280 (old sum)

and see more problem on statics, i recive this error (i know the problem, i send it only for more data)

this the sensor template

  - name: FV immissionew
    state: >
          {% if states ('sensor.on_grid_export_power') | float > 0 %}
          {{ states('sensor.on_grid_export_power') | float /1000}}
          {% else %}
            {{0}}
          {% endif %} 
    unit_of_measurement: 'w'
    device_class: energy
    state_class: total_increasing

and this is sensor on tab energy

    source: sensor.fv_immissionew
