Which entity stores the net grid consumption?

Configuration
1

So I am using an Iammeter module to monitor my grid. It provides me two sensors which I have configured in the Energy dashboard:

sensor.imeter_xxxxxxxx_importenergy_x
sensor.imeter_xxxxxxxx_exportenergy_x

The energy dashboard uses these to calculate and display the “Grid Total”.

Is that value available to use via an entity?

I have created a template sensor which I use as input for daily, weekly, etc… Utility Meter helpers, but I regularly get spikes which basically makes these helpers unusable.

  # Grid net energy
  - sensor:
      - name: "Grid Net Energy"
        unique_id: grid_net_energy
        unit_of_measurement: "kWh"
        state_class: total_increasing
        device_class: energy
        state: >
          {% set import = states('sensor.imeter_613677eb_importenergy_x') | float(0) %}
          {% set export = states('sensor.imeter_613677eb_exportenergy_x') | float(0) %}
          {{ import - export }}

Apparently, the built-in “Grid Total” does not have this issue so I’d like to build mob helpers on that value.

You need to add an availability template to the above sensor:

# Grid net energy
  - sensor:
      - name: "Grid Net Energy"
        unique_id: grid_net_energy
        unit_of_measurement: "kWh"
        state_class: total_increasing
        device_class: energy
        availability: >
          {{ has_value('sensor.imeter_613677eb_importenergy_x') and 
             has_value('sensor.imeter_613677eb_exportenergy_x') }}
        state: >
          {% set import = states('sensor.imeter_613677eb_importenergy_x') | float(0) %}
          {% set export = states('sensor.imeter_613677eb_exportenergy_x') | float(0) %}
          {{ import - export }}

If you don’t, when one or more of the base sensors are available, they are counted as 0, creating weird values that lead to the spikes.

Hi Edwin,

Thnx for the help :sunglasses:. I’ll give it a shot right away.
