Statistic Templates

Configuration
1

Hi All,

Trying to setup the new energy information and my various items are all in different units of measurement, so I have created template sensors to align everything… but because of the new requirement that sensors be classed as ‘statistics’ for use in the energy component, none of my new templated sensors display as valid.

I saw that to create a sensor as a statistic, you need to add the

state_class: 'measurement'

but template sensors cannot have this attribute.

Can someone explain how to setup template sensors that can be used in statistics?

Simon.

Did you try adding the attribute with customize instead of directly to the config. This is not recommended but may work.

Unfortunately the answer is, wait patiently for support to be added.

If you can feed your template sensors to Utility Meters and use the utility meter outputs this may also be a workaround.

If you use the ‘modern’ style of template sensors instead of the legacy style, they can be added

example from my installation :

template:
  - sensor:
      - name: "House electricity energy"
        unit_of_measurement: 'kWh'
        state: >
          {{ (states("sensor.mains_consumed_energy") | float + states("sensor.upstairs_consumed_energy") | float) + (states("sensor.extra_consumed_energy") | float)  | round(2) }}       
        device_class: energy
        state_class: measurement      
        attributes:         
           last_reset: '1970-01-01T00:00:00+00:00'

Thanks for the ideas both of you.

I have one of the sensors (the house production one) working, the other two are setup the same way so unsure what the issue is.

Here is the code for those interested:

        friendly_name: 'Energy Consumption'
        unit_of_measurement: 'W'

      energy_grid:

Oh great. See: https://community.home-assistant.io/t/automatically-convert-from-legacy-template-to-modern-template-format/327555/2 Guess I will be making the effort after all.

At least they can be in packages now :rofl:

Sigh. :weary: Wonderful.
