Hi.
I have a Zenner watermeter and it has one gauge with metal on top of it.
Iā€™ve tested and the Homewizard reads that gauge. Iā€™m now wondering if the homewizard reads it correctly because the gauge is the x0,001 version so 1 cycle of that gauge is 10 litres. Does the homewizard think that the 1 cycle is 1 litre?

Hi
I use a Homewizard WIFI Watermeter for nearly 15 months by now and am totally satisfied with its usage. Now I added it to HA and am puzzled on how to reset the counter of total Water used - is there a way to do this without resetting the complete device? I wanted to start ā€œall newā€ with my HA instance up and running.

You canā€™t do this with the device, but you can create a utility sensor (search the docs for this) and reset that :wink:

I added this to my configuration.yaml to get it to match my actual meter reading. 2 years on and near spot-on in measurements.

template:
  - sensor:
      - name: Water Meter Reading
        unique_id: water_meter_running_total
        state_class: total_increasing
        unit_of_measurement: mĀ³
        device_class: water
        icon: mdi:gauge
        state: "{{ (382.188 + states.sensor.water_meter_total_water_usage.state |float) }}"

The number was the difference between what Homewizard was reporting and the actual meter reading, so it reports the ā€˜actual meter readingā€™.
