Hello, I live in Albi in the Tarn region. In your case, try this formula.:

sensor:
  - platform: pulse_meter
    pin: RX
    name: "${friendly_name} Cpt Eau Piscine"
    unit_of_measurement: "L/min"
    icon: "mdi:water"
    filters:
      - lambda: return x / 12.0;  # Convertit impulsions/min en L/min (1 litre = 12 impulsions)
    total:
      name: "${friendly_name} Cpt Eau Piscine Total"
      unit_of_measurement: "m³"
      accuracy_decimals: 3
      device_class: water
      state_class: total_increasing
      filters:
        - lambda: return x / 12000.0;  # Convertit impulsions en m³ (1 m³ = 12 000 impulsions)
