Display of water consumption in the Energy dashboard from a knx meter

[Stives25]

Hi,
I was able to display in the “Energy” dashboard the consumption of electricity and gas from indexes stored in knx meters but I am blocked for the display of water consumption.

knx.yaml

sensor:
#Compteur elec (Wh)
  - name: compteur_elec
    state_address: "9/7/0"
    type: "active_energy"
    
    
#Compteur gaz (m3)
  - name: compteur_gaz
    state_address: "9/7/1"
    type: "volume"
    state_class: total_increasing

#Compteur eau (litres)
  - name: compteur_eau
    state_address: "9/7/12"
    type: "volume_liquid_litre"
    state_class: total_increasing

customize.yaml

ensor.compteur_gaz:
  device_class: gas
  unit_of_measurement: "m³"

sensor.compteur_eau:
  device_class: water
  unit_of_measurement: "L"

KNX

The list to add a source for water consumption is empty

As you can see in the input field, the water consumption expects an entity reporting its usage in m³ or gallons. You’re measuring liters. You can divide your liter value by 1000 and set the unit to m³, and you should be able to select it in the dropdown.

With version 2022.12.4 I can display the water consumption history with the following code:
knx.yaml

#Compteur eau (m3)
  - name: eau_m3
    state_address: "9/7/3"
    type: "volume"

customize.yaml

sensor.eau_m3:
  device_class: water
  unit_of_measurement: "m³"

It’s not perfect :

1. On the line device_class: water I always have this error message :
