Gas consumption in kWh

[developerGM]

Hi, why if I add these 2 entities

Ariston domestic hot water gas consumption Ariston central heating gas consumption

on Energy board, I see kWh and not SMC ?

this is a gas consumption, not an electricity consumption.

[developerGM]

No, there isn't a sensor about it.

But my question is why I see kWh in energy board and not SMC (or m3)?

I pay by SMC consumption so I prefer see this value

Hi @developerGM

You could update desire units through ariston web portal / mobile app, here is example for web portal

Or through home assistant - an ariston instance configuration

Hello guys, same here. I prefer to see Smc instead of kWh. I've tried to change the parameters in the app and in the integration aa shown by @developerGM but still works onlt with kWh WTF :(

[developerGM]

Yes, confirm that if you change the params in App (Ariston) or in HomeAssistant, not works. In Energy board I see always kWh

As @fustom (see https://github.com/fustom/ariston-remotethermo-home-assistant-v3/discussions/87#discussioncomment-5179684) says:

The official app convert the kWh energy locally based on those settings. But you can do the similar thing in HA by change the settings for the [ariston_central_heating_gas_consumption] entity and set different unit of measurement.

To solve this problem, I created a couple of sensors: https://github.com/fustom/ariston-remotethermo-home-assistant-v3/discussions/87#discussioncomment-6123134

@salvadorbs Ok, I will test it, thanks To integrate I need to add your code on sensors.yaml file?

[salvadorbs]

Configuration.yaml or your sensor yaml file, if you are using it.

[developerGM]

Configuration.yaml or your sensor yaml file, if you are using it.

@salvadorbs I am testing on sensors.yaml but I don't understand what kind of platform I need to write

• platform: XXX

[salvadorbs]

Why platform? You do not need it. https://www.home-assistant.io/integrations/template/#state-based-template-binary-sensors-buttons-images-numbers-selects-and-sensors

Same issue here.

SMC in Ariston/ATAG webportal, but not the option to use SMC (or M²s) is not possible to select.

Small update for sensor gas:

template
  - sensor:
      - name: "Ariston Gas Riscaldamento m³"
        unique_id: ariston_gas_riscaldamento
        state: "{{ (states('sensor.ariston_central_heating_gas_consumption') | float / 10.69) | round(2) }}"
        unit_of_measurement: "m³"
        icon: mdi:cash
        device_class: gas
        state_class: total
        attributes:
          last_reset: "{{states.sensor.ariston_central_heating_gas_consumption.attributes.last_reset}}" 

Changed state_class from total_increasing to total and added last_reset attribute, like original sensor. I noticed that, especially with the heating sensor, the total_increasing state ignored the new values if they were similar (see home assistant docs). So I decided to use the state_class and last_reset attribute from the original sensor. For now it seems to work.

@salvadorbs how can I set the card in HA to show always the m3 of today? so only totale current day

[salvadorbs]

I use these sensors in the energy dashboard. In any case, you should use stat cards:

• Statistic card https://www.home-assistant.io/dashboards/statistic/
• Statistics graph card https://www.home-assistant.io/dashboards/statistics-graph/

Stat type = change Period = today

[developerGM]

This is perfect but I see different values

In HA, I see for this month 30.46m³ In Ariston app, I see for december a total of 64SMC

Why?

[hellcatmon]

It could be missing consumption because of unavailable sensor values from API (API calls successful less that 50% in my case). By default the gas consumption sensor is updated every hour. In case bad response the last hour consumption will be unavailable and it could affect the total numbers. Try to set more frequent gas sensor updates (e.g. every 10 mins) to be guaranteed a consumption value every hour.
