Hi.
I have a Zenner watermeter and it has one gauge with metal on top of it.
I’ve tested and the Homewizard reads that gauge. I’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 “all new” with my HA instance up and running.

You can’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: mÂł
        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 ‘actual meter reading’.

Doesn’t work for me - even after waiting for one full day I still get the warning message

saying statistics not defined / entity not available. Doesn’t matter whether I use “,” or “.” for decimal separation with configuration.yaml and I double checked that the sensor.water_meter_total_water_usage part matches my local sensor ID.

Is it possible to get data to HA on batteries? Simple Q :slight_smile:
I think i searched whole thread and didnt get direct answer.

edit: never mind, there is HACS solution to fill the gap. You can’t integrate directly to HA on batteries, so you must get data from their cloud. Thanks anyways :slight_smile:
