Hi everyone,
I built a free public API for Home Assistant automations that provides forecasted electricity prices and CO2 values for several European markets.
The idea is simple:
- use it for dynamic tariff automations
- shift EV charging or appliances into cheaper hours
- or prefer lower-CO2 hours instead of only lower-price hours
No custom integration is required at the moment. It works with the public endpoints plus standard REST/template sensors in Home Assistant.
Setup guide and more detailed Information:
Currently supported:
DE, NL, BE, DK1, DK2, FR, AT, CZ
soon NO1-5
later the rest of europe
A typical use case would be:
- charge when the forecasted price is low
- or charge only when price is acceptable and CO2 is below a chosen threshold
A few notes:
- these are forecasted market values
- household-specific grid fees, taxes, and supplier add-ons are not always included automatically
- for many automations, the relative curve is more important than the exact final household price
Feedback is welcome.
