Allumage d'un gpio avant lecture ADC:
  sensor:
    - platform: adc
      pin: A0
      id: soil_sensor
      internal: true
  
      #update_interval: 60s
    -  platform: template
      name: "Humidité Sol"
      id: humidite_sol
      accuracy_decimals: 4
      unit_of_measurement: "%"
      icon: "mdi:water-percent"    
  
  interval:
    - interval: 30s
      then:
        - output.turn_on: soil_power
        - delay: 500ms
        - component.update: soil_sensor
        - sensor.template.publish:
            id: humidite_sol
            state: !lambda |-
              return id(soil_sensor).state;      
        - delay: 200ms
        - output.turn_off: soil_power
    
  output:
    - platform: gpio
      pin: D5
      id: soil_power
