Homeassistant - sometimes 0 m³ and always gaps in the graphics.

[Mkay505]

First of all - great project.

I have a problem with the display of the water meter value in Homeassistant.
Sometimes the value is given as 0 m³, sometimes the right value is present.
As a result, the graphics have gaps.
Can I fix the fact that it always shows the last value and the graphic curve is continuous in Homeassistant?

My code in a "sensor" folder as "wasserzahler.yaml":

• platform: mqtt #Minus instead of point!

  name: "Wasserzähler"
  state_topic: wasserzaehler/main/json
  value_template: "{{ value_json.value }}"
  unit_of_measurement: "m3"
  icon: "mdi:water"

If there is a false value, this is not transfered. You need to make a filter on the receiver side if you want to remove those inputs.

Hi,

does anyone has a proposal for such a filter?
Sorry, but I'm not yet so skilled in programming Homeassistant

I had the exact same issue. Now I simply use the Home Assistant outlier filter, which works great for me:

rest:
  - resource: http://192.168.1.51/wasserzaehler.html
    scan_interval: 300
    sensor:
      - name: Water Consumption (L)
        unique_id: water_consumption_l
        unit_of_measurement: 'l'
        icon: mdi:water-circle

sensor:
  - platform: filter
    name: Water Consumption (L) Filtered
    unique_id: water_consumption_l_f
    entity_id: sensor.water_consumption_l
    filters:
      - filter: outlier
        window_size: 4
        radius: 200

I am using the JSON API with the following code:

  - platform: rest
    resource: http://gasmeter.fritz.box/json
    name: "Gaszähler"
    unit_of_measurement: "m³"
    device_class: "gas"
    icon: "mdi:meter-gas"
    value_template: "{{ float(value_json.main.value) }}"
    json_attributes_path: "$.main"
    unique_id: "gasmeter"
    state_class: "total_increasing"

I think generally the JSON api is a bit more safe to use, though unfortunately sometimes I have errors with that too. I didn't quite got to the bottom of it.

You could try to use the Filter sensor using your MQTT sensor as the base: https://www.home-assistant.io/integrations/filter/ with the setting "range" and a lower_bound of your current value. That way it should filter out the 0 values.

Maybe the JSON MQTT topic gets sent after every run?
I use the value topic and I dont see gabs in Homassistant.

Here my config:

- platform: mqtt
  state_topic: "wasserzaehler/main/value"
  name:  "Wasserzähler"
  unique_id: Wasserzaehler
  state_class: measurement
  device_class: gas
  unit_of_measurement: "m³"

- platform: mqtt
  state_topic: "wasserzaehler/main/raw"
  name: "Wasserzähler_raw"
  unique_id: Wasserzaehler_raw
  state_class: measurement
  device_class: gas
  unit_of_measurement: "m³"

- platform: mqtt
  state_topic: "wasserzaehler/uptime"
  name: "Wasserzähler Uptime"
  unique_id: Wasserzaehler_uptime
  state_class: measurement
  device_class: duration
  unit_of_measurement: "s"

Thanks for all your input. I started to consolidate it in https://github.com/jomjol/AI-on-the-edge-device/wiki/Integration-Home-Assistant
