Combining modbus energy data for energy dashboard usage

[skitex (Stinuz)]

dear,

I’m moving from a KNX energy meter towards a modbus TCP energy meter (countis e27)

I can succesful retrieve the values but I don’t succeed to reconfigure my energy dashboard.

to be able to get the correct kWh value I need to combine two modbus values (see picture below)

I combine the data with a template sensor to get the proper value

- platform: template
  sensors:
    countis_total_energy_kwh:
      friendly_name: "Countis Total Energy kWh"
      unit_of_measurement: 'kWh'
      value_template: "{{ (states('sensor.countis_net_active_energy_balance') | float) + (states('sensor.countis_net_residual_active_energy_balance') | float / 10000) }}"
      device_class: 'energy'

this looks like this

But I’m unable to select this newly created sensor inside the Energy dashboard configuration.

Help is welcome
Stijn

I was using the old templating option. It works with the new templating integration

template:
  - sensor:
      - name: "Countis Total Energy kWh"
        unit_of_measurement: "kWh"
        state: >
          {{ (states('sensor.countis_net_active_energy_balance') | float) + (states('sensor.countis_net_residual_active_energy_balance') | float / 10000) }}
        device_class: energy
        state_class: measurement
        last_reset: '1970-01-01T00:00:00+00:00'

this thread solved my problem

How to enable power consumption statistics

Have found it: (from 123) The documentation doesn’t show the state_class option for legacy Template Sensor. My understanding is that the energy integration includes entities containing that option (and set to measurement). Without that option, the entity is excluded. Easy way to find out is to convert one or more of your Template Sensors from legacy to the new format and add state_class: measurement. https://community.home-assistant.io/t/2021-8-0-feel-the-energy/326853/83

- sensor:
  - name: "Countis Total Energy Wh"
    unit_of_measurement: "Wh"
    state: >
      {{ (states('sensor.countis_net_active_energy_balance') | int / 0.001) + (states('sensor.countis_net_residual_active_energy_balance') |int / 10) | round(0) }}
    device_class: energy
    state_class: total_increasing

I ended up with the code above to get the measurements right in the dashboard
