Energy Dashboard calculate "consumption - solar - return"

Configuration
1

Hi,

Enmergy calculation of the three sensors

  • Grid Consumption - Shelly 3EM sensor
  • Production Solar Sensor Live, Daily & Total
  • Export ?? no Sensor available

Energy export is only when I produce more than I consume.
I’m still missing a sensor for the energy dashboard.
What is the best way to calculate this?

I currently have my solar sensor under “Production” & “Return”.
But that leaves the “Sefl-consumed” scale at 0% - logical in itself.
But I would like it to be 100% with this picture status, because I use the solar power myself.

Hi,

I built a solution that should work.

If the “solar” value is greater than the consumption, the value is displayed in the “export” sensor.
If the value is smaller - the “export” sensor indicates a “0.0”.

Sensor config:

  - platform: template
    sensors:
      energy_shelly3em_total:
        unit_of_measurement: "kWh"
        value_template: "{{ states('sensor.shelly_a') | float | round (2) + states('sensor.sensor.shelly_b') | float | round (2) + states('sensor.sensor.shelly_c') | float | round (2)}}"
        device_class: energy
        
  - platform: template
    sensors:
      energy_export:
        unit_of_measurement: "kWh"
        value_template: >-
           {% if states('energy_shelly3em_total') | float(0) - states('sensor.energy_solar') | float(0) < 0 %}
              {{(states ('sensor.energy_solar') | float(0) - states('energy_shelly3em_total') | float(0)) | round (3) }}
           {% else %}
              {{(states ('0.0') | float(0)) |round(3) }}
           {% endif %}      
        device_class: energy

Maybe it is helpful for you…

hello, thanks for your suggestion, i can see the sensor, but it’s not shown on the combobox “return to grid” on the energy dashboard config.
i did something wrong? thank you,

Here is my current config - hope it helps.
