Calculate total daily energy with Utility Meter

Configuration
1

Hi all,

I’ve just installed HA and I’m puzzling with Utility Meter. I’ve installed the DSMR component and copy and pasted the script for calculating the daily and monthly energy consumption into my configuration.yaml.

utility_meter:
  daily_energy_offpeak:
    source: sensor.energy_consumption_tarif_1
    name: Daily Energy (Offpeak)
    cycle: daily
  daily_energy_peak:
    source: sensor.energy_consumption_tarif_2
    name: Daily Energy (Peak)
    cycle: daily
  daily_gas:
    source: sensor.gas_consumption
    name: Daily Gas
    cycle: daily
  monthly_energy_offpeak:
    source: sensor.energy_consumption_tarif_1
    name: Monthly Energy (Offpeak)
    cycle: monthly
  monthly_energy_peak:
    source: sensor.energy_consumption_tarif_2
    name: Monthly Energy (Peak)
    cycle: monthly
  monthly_gas:
    source: sensor.gas_consumption
    name: Monthly Gas
    cycle: monthly

This works perfectly. But when I wan’t to calculate the total energy per day and per month than I get returned ‘none’. I’ve copy and pasted the code into my configuration.yaml

template:
  - sensor:
    - name: 'Daily Energy Total'
      device_class: energy
      unit_of_measurement: kWh
      state: >
        {% if is_number(states('sensor.daily_energy_offpeak')) and is_number(states('sensor.daily_energy_peak')) %}
          {{ states('sensor.daily_energy_offpeak') | float + states('sensor.daily_energy_peak') | float }}
        {% else %}
          None
        {% endif %}

    - name: 'Monthly Energy Total'
      device_class: energy
      unit_of_measurement: kWh
      state: >
        {% if is_number(states('sensor.monthly_energy_offpeak')) and is_number(states('sensor.monthly_energy_peak')) %}
          {{ states('sensor.monthly_energy_offpeak') | float + states('sensor.monthly_energy_peak') | float }}
        {% else %}
          None
        {% endif %}

I can’t figure out where it’s going wrong. Can someone point me in the right direction?

Kind regards,
Bjorn
