Look at the example here (a state-based template sensor).

Can somebody please tell me what i am doing wrong with the gas meter?
It does not takeover the number of decimals?

I had to make my own nuts meter helper but also make my own sensor

  - sensor:
      - name: Monthly_Gas_Meter_in_m3
        unit_of_measurement: L
        device_class: current
        state_class: measurement
        state: >
          {{ states('sensor.monthly_gas_meter') | float(default=0.0) | multiply(1000) | round(0)}}
