Use Voltcast price forecasts with evcc

Feed local European day-ahead prices and forecasts into an evcc charging workflow.

Short answer

Voltcast supplies zone-specific market prices at their native resolution. Use the same zone in Voltcast and evcc, verify the displayed intervals, and keep evcc safety limits authoritative.

Forecast performance is published daily on the public accuracy board; losing zones remain visible.

Live DE-LU example: €117.43/MWh for 2026-08-29 22:00–23:00 GMT+0000; source smard.

Set it up

  1. 1 Create Home, choose the bidding zone configured for your charge point, and create an API key.
  2. 2 Configure the merged Voltcast tariff integration in evcc with that zone and key.
  3. 3 Confirm today and tomorrow have the expected number of market intervals.
  4. 4 Run notification-only for one day before enabling price-aware charging.

Verify the data first

curl -H "Authorization: Bearer YOUR_API_KEY" "https://voltcast.com/api/v1/prices/DE-LU"

Check zone, units, source, issuance time, native resolution, and gaps before connecting a physical device. An example live public context is at /zones/DE-LU.
