Tell HA that the sensor is a water sensor

Configuration
#1

Hello,
I like to add my water meter to the energy dashboard. Only I don’t get the HA configuration right for it.
I got this sensor working in my config:

sensor:
  - platform: serial
    name: Water Meter
    serial_port: /dev/serial/by-id/usb-1a86_USB2.0-Ser_-if00-port0
    baudrate: 9600 
    value_template: "{{ value.split(':')[1][:-1] }}"

I didn’t find any usefull information how to configure the sensor for this. So what do I have to add to the config so Ha knows this is a water sensor?
Thanks

Refer to the example posted here:
Manual Customization

Add the following two lines then restart Home Assistant (or execute Developer Tools > YAML > Reload all YAML Configuration).

sensor.water_meter:
  device_class: water

Here’s the result:

thanks, for the help. Only it doesn’t work yet. Is the order important?
I now have this:

homeassistant:
  customize:
    sensor.water_meter:
      icon: "mdi:water-pump"
      unit_of_measurement: "m3"
      device_class: water
sensor:
  - platform: serial
    name: water_meter
    serial_port: /dev/serial/by-id/usb-1a86_USB2.0-Ser_-if00-port0
    baudrate: 9600 
    value_template: "{{ value.split(':')[1][:-1] }}"

You’re going to need more than just device_class to get a sensor included in energy statistics. You will also need state_class and unit_of_measurement.
