Energydahsboard muliply factor energy measurement "Wandlermessung"

Hi all,

thanks for this nice forum here. I’m doing my first steps with home assistant so maybe the result is very easy, I only didn’t get the solution. so would be good if you can give me a hint.

I’m having a current measuring with big energy at a bulidung. 80A.
This measurement ist done by a current converter because it’s not directly measureed. (Wandlermessung)
This factor has to be added afterwards. So i’m getting the correct value via tasmota and a smart meter interface.

My questions is where i can add a factor (in my case of 15) for getting the correct kwh result vom the energymeter.

thanks in advance for helping to find this option.

greetings
Michael

Hello, you can create a sensor with the value from the energy meter (your existing sensor) multiplied by 15…
but make sure you measure an energy (KWh) and not a power (W or KW)

Example for energy (I am converting gas consumption from m3 to KWh), this sensor (called sensor.smappee_usage_gaz_c_kwh) has to be defined in template.yaml :

  - name: "Smappee Usage Gaz C Kwh"
    state_class: total_increasing
    device_class: energy
    unit_of_measurement: "kWh"
    state: >
      {{ states('sensor.consommation_gaz_m3_jour') | float(default=0) * 11.2681 | round(3) }} 
    unique_id: "Smappee_Usage_Gaz_C_KWH"

thats sounds perfect. thank you. easier than expected. but not clear for me as beginner. thanks you.

One question again. the multiplier is now very easy.
i’ve added the following to my configuration.yaml but the new template sensor is not showing up in my eneergy dashboard.

template:
  - sensor:
      - name: "Verbrauch"
        unique_id: 8f43aa7e-86e3-11ed-a1eb-0242ac120002
        device_class: energy
        state_class: total_increasing
        unit_of_measurement: "kWh"
        state: >
          {% set raw_value = states('sensor.tasmota_total_in') | float %}
          {% set factor = 15 | float %}
          {{ states if states in [0, '0.0', 'unknown', 'unavailable', 'none'] else (raw_value * factor)| float}}

Did you add it in dashboards?

what you mean with that? i try to add this value to the enery dashboard. at the moment is only displayed aa normal sensor.

how i add this to the dashboard?
