Make the odometer suitable as a long-term statistic

[mthmulders]

Is your feature request related to a problem? Please describe.
I'd love to see a chart of the mileage of my Skoda car. I thought I would need a Statistics Graph Card for that, but it doesn't show the odometer as a source.

Describe the solution you'd like
The Expected data source not listed page suggests that the state_class of the entity may not be correct.

Describe alternatives you've considered
n/a.

Additional context
I'm quite a starter when it comes to using Home Assistant - so if my understanding of how HA or this Skoda integration works is insufficient, I'm definitely open for alternative approaches.

Seems reasonable. We're currently setting state_class for 'battery_level', 'adblue_level', 'fuel_level', 'charging_time_left', 'charging_power', 'charge_rate', 'electric_range', 'combustion_range', 'combined_range', 'outside_temperature'. (see

homeassistant-skodaconnect/custom_components/skodaconnect/sensor.py

Line 65 in 6bde424

def state_class(self):

)

Settings state_class = total for the appropriate sensors (like odometer) seems valid. Setting state class does result in long-term statistics being stored for it.

Note that if all you want is a graph with recent values I'd recommend looking into mini graph card and apex charts card, which aren't tied into the native HA statistics stuff.

E.g. minigraph with the odometer sensor (so without state_class):

type: custom:mini-graph-card
hours_to_show: 168
entities:
  - sensor.tmxxxxxxxx_odometer

I made my own "helper" in configuration.yml file like this

• name: "ENYAQ KILOMETRES"
  state: >-
  {{ states('sensor.skoda_enyaq_odometer') }}
  unit_of_measurement: km
  device_class: distance
  state_class: total_increasing

I think this odometer needs state_class: total_increasing attribute. This works fine for me.

In Tesla integration the odometer contains this total_increasing

I would like to be able to plot a statistics bar chart of the daily mileage based on the odometer reading but I can't plot the "change" in a statistics chart, it only gives the total Odometer. I suspect this is what the original poster was also referring to. If there is a way of doing this with the current code in HA then I am happy to learn how to do it.

@CaptSB , as mentioned previously, take a look at the ApexCharts card.

type: custom:apexcharts-card
graph_span: 7d
series:
  - entity: sensor.tmxxxxxxxxx_odometer
    type: column
    group_by:
      func: diff
      duration: 1day

@MaZa78 @mthmulders , setting state_class: total_increasing for the odo sensor sounds like the right thing to do. I'll take a look when I have time but feel free to submit a PR.

That is perfect! I now have the daily mileage chart I wanted! Many thanks Richard Sent from Gmail Mobile
