How to create a new (Homewizard water) sensor to keep track of daily usage

[RapTile]

Hi,

The homewizard watermeter has two sensors that i can read (translated):

• sensor.watermeter_actual_water_usage (which indicated the usage in Liter)
• sensor.watermeter_total_water_usage (which indicates the usage in m3)

I’ve tried several things but i can’t get a new sensor that tracks the usage daily.

Besides other things, i tried the code below with the other (current) sensor as well but i can’t get it to work.

What am i doing wrong? I can see the sensor but the value stays zero

utility_meter:
  daily_water:
    source: sensor.watermeter_total_water_usage
    name: Water Usage Daily Utility Config
    cycle: daily

template:
  - sensor:
      - name: "Water Usage Daily"
        unique_id: water_usage_daily
        unit_of_measurement: "L"
        device_class: water
        state_class: total_increasing
        state: >-
          {{states('sensor.daily_water') | float(0)  * 0.001}}

If I am not mistaken; You can create a utility meter directly from the UI without having to make any YAML. After connecting the Water meter to Home Assistant you can create a daily-usage meter out of the box.

1. Click here →
2. Then hit ‘Create helper’ → Utility meter
3. Select ‘Total Liter’ from your water meter, and configure the rest (self explaining)

Hope this helps . if it does you can mark this as ‘solution’, that will help others.

Thanks for your quick reaction!

I tried that but the status was unknown:

After turning on the water to test,
It was working.

Thanks a lot for your help!

Because the total value is in m3,

I created a template so it could present the value in Liters.

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

The Liters are not being calculated correctly

Where did i go wrong?

Because of the measurement in the helper i changed the template.

  - sensor:
      - name: Daily_Water_Meter_in_Liter
        unit_of_measurement: L
        device_class: current
        state_class: measurement
        state: >
          {{ states('sensor.daily_water_meter') | float(default=0.0) | multiply(100) | round(2)}}

That seems to be working:

But with a larger amount this was not working so i had to bring it back to 1000.

It would be 16,6 and thats not good So for a lower usage it is less accurate.

Is there a way to also print the decimal value if the volume is less then 10?

Just as Raptile I’m running into some issues.
I can’t get it to duplicate the values that the HomeWizard app is displaying
Could you paste your helper and dashboard card in this topic please?

i´m also struggling!

[RapTile]

anybody got it working eventually?

This is working for me. I setup daily, weekly, monthly and quarterly helpers.
A couple things to check:

• use the total consumption sensor (or make sure you specify during creation that it is a delta value)
• know how often the sensor reports and watch the value in the devtools State tab to see if there is any change over time
• if the helper isn’t working, try creating it in yaml. This also worked for me:

daily_water_use:
  source: sensor.watermeter_value
  cycle: daily
