cool! |

Ich stehe gerade wieder auf dem Schlauch. Wo muss ich das eintragen? |
|
I added a template for both tariffs. |
Ih wuerde keine Zeit darein investieren - gibt zu viele Preismodelle. evcc hat mit dem charge/tax oder Formel alles dabei, um das lokal zu loesen. |

Hi, this is my mistake. I accidentally enabled the paywall too early. I actually wanted to test it properly on other platforms first. For now, I will reopen the forecast horizon again. Due to the high traffic, the costs are becoming significant for me, so I am considering making the forecast paid from, for example, 48 hours onward. I am thinking of a very small amount, such as €1 per month. I think that would be fair. Please feel free to share your opinion on this. I would like to keep CO2 completely free. I hope that together we can reduce our CO2 footprint a little and help slow down climate change. I would like to unlock these premium features using an API key. If you are interested in taking part in a test phase, I would be very happy to hear from you. Just send me a short informal email and I will provide you with a test key. I would be glad if we can find a good way forward together, so that everyone is happy. Best regards, |

Starting on October 1, 2026, the electricity price forecast will be limited to a maximum of 48 hours when used without an API key. With a Private Pro API key, the full forecast horizon of up to 120 hours will remain available. The CO₂ forecast will continue to be completely free of charge and can still be used without an API key for the full 120-hour forecast period. Climate protection is particularly important to me, so I want to keep this part of the service freely available to everyone. Existing evcc configurations will continue to work. Without an API key, the electricity price data will simply be shortened to 48 hours. The endpoint will not return a hard error, so existing setups should not suddenly stop working. The updated configuration, including an example using a Bearer token, is available here: https://energypriceforecast.eu/de/evcc-strompreis-co2-prognose/ The Private Pro subscription is mainly intended for power users and supporters who would like to use the extended 120-hour electricity price forecast. The small subscription fee is not intended to turn this project into a large commercial service. It simply helps me cover the ongoing server and development costs of a project that I have built and continue to maintain on my own. The free 48-hour electricity price forecast should still be sufficient for many common use cases, while users who benefit from the longer forecast horizon can support the project and help keep the service running. Would anyone be interested in testing whether the new API-key integration works correctly with evcc? I would especially like to verify that the Bearer token is transmitted correctly, that the full 120-hour forecast is returned, and that existing configurations continue to work as expected. The first person willing to test the integration will receive one year of Private Pro access free of charge as a thank-you for helping me verify the setup. Please reply here or send me a private message if you would like to test it. |

I found a Tester, thank you! |

Hi zusammen,
ich habe für meine Strompreis- und CO2-Prognose einen evcc-kompatiblen Custom-Tariffe-Endpunkt gebaut und lokal mit evcc 0.305.1 getestet.
Der Endpunkt liefert das von evcc erwartete Forecast-Format mit start, end und value. evcc akzeptiert die stündlichen Werte und stellt sie intern viertelstündlich dar.
Beispiel Preisprognose Deutschland:
tariffs:
currency: EUR
grid:
type: custom

uri: https://api.energypriceforecast.eu/api/v1/evcc/tariff?country=de&type=grid&hours=120
Beispiel CO2-Prognose Deutschland:
tariffs:
co2:
type: custom
forecast:
source: http
uri: https://api.energypriceforecast.eu/api/v1/evcc/tariff?country=de&type=co2&hours=120
Unterstützte Länder/Preisregionen aktuell:
DE, NL, BE, DK1, DK2, FR für Preis
DE, NL, BE, DK1, DK2 für CO2
Hier meine Erklär und Landing-Page:
https://energypriceforecast.eu/de/evcc-strompreis-co2-prognose/
Wichtig:
Die Preiswerte sind Börsen-/Prognosewerte in EUR/kWh bzw. für DK optional DKK/kWh. Persönliche Netzentgelte, Steuern und Anbieteraufschläge sind darin nicht automatisch enthalten. Für reine Ladezeit-Optimierung ist vor allem der relative Verlauf relevant.
Bei Interesse kann ich hier gerne nachsteuern.
Ich würde mich über Feedback freuen, ob das in echten evcc-Setups sauber funktioniert und ob ein zusätzlicher Endpunkt mit Haushalts-Endpreis-Annahmen sinnvoll wäre.
Die Besonderheit bei meiner Preisvorhersage ist, dass die Qualitätszahlen öffentlich einsehbar sind und meiner Meinung nach ganz ordentlich sind :) -> https://energypriceforecast.eu/
Die CO2-Prognose ist noch in der Beta. Der Verlauf passt schon einigermaßen, an einem einheitlichen System arbeite ich noch.
Ich freue mich auf euer Feedback
Hendrik
