Current gas price is dropping to 0 every night.

Current gas price is dropping to 0 every night.

I added a sensor to my system to fix the gap and it works with the energy dashboard.
But would be nice if it's done within the integration.

- sensor:
    - name: "zonneplan current gas tariff fix"
      unit_of_measurement: "EUR/m³"
      state: >-
        {% if is_state('sensor.zonneplan_current_gas_tariff', 'unknown') or is_state('sensor.zonneplan_current_gas_tariff', '0') %}
          {{ states('sensor.zonneplan_current_gas_tariff_fix') }}
        {% else %}
          {{ states('sensor.zonneplan_current_gas_tariff') }}
        {% endif %}`

Released a new version with the feature https://github.com/fsaris/home-assistant-zonneplan-one/releases/tag/0.0.13

Need to check the exact API response for this.

Could be there is no value at all between 0h and 4h.

I'm not buying energy from Zonneplan. But if you are sure what the "rules" are regarding the price and when it's applicable it should be possible to build this in the integration

It is the same in the Zonneplan app. The gas price should remain the same until the next day price takes effect. This is not at 12AM but at 6AM CET.

This is an excerpt from the documentation for TTF Day Ahead: The Day-Ahead contract (DA) is a strip of a single gas day from the next weekday at 06:00 (CET) to 06:00 (CET) on the following calendar day.

Nice workaround, thanks!

[fsaris]

Do we know if the value is none or 0 during the night?
Looks that this change isn't correct a27ab2a that should have prevented it from going to 0. Or we really got 0 from the api

And only fixing this isn't enough right? It should also update at 6h instead of 4h

[graafish]

My solution was a quick fix. I thought the value was 0 because that's what showing in the graph.
Didn't know the price starts at 6am so if it does it needs a fix too.
Nice you're looking into this.

Would be great if this can be fixed. Thanks Frans for all your great work.

[fsaris]

Okay, in current master the 0 values are gone during 0:00 and +/- 4:00.

Currently looking into only updating the gas tariff once a day at 6:00

[loedeman]

Wow, sounds great 👍!

[fsaris]

Current main version updates the gas tariff once a day at 6

[loedeman]

Sounds great, thanks. I just changed the HACS repo to main, hope to see the new behavior tomorrow 😀👍!

[loedeman]

Thanks! I had some trouble reproducing it because I rebooted HA at the wrong time 🤗. But confirming it works indeed, nice!!!

Looks good, thank you for the effort @fsaris!
