bfe-tariffs-data

Community-maintained Swiss PV feed-in tariff database for the ha-bfe-rueckliefertarif Home Assistant integration.

What's here

• tariffs.json — utility-specific tariffs + federal Mindestvergütung floors per EnV Art. 12 Abs. 1bis (AS 2025 138). Date-versioned via half-open [valid_from, valid_to) intervals so each yearly utility update appends a new record without editing past data.
• schemas/tariffs-v1.schema.json — JSON Schema (Draft 2020-12) the integration validates against on every fetch. Schema bumps are versioned via schema_version (semver).

How the integration consumes this

The integration fetches tariffs.json daily from raw.githubusercontent.com, validates against the bundled schema, caches in <config>/.storage/, and falls back to its own bundled copy on any failure (network or schema violation). Manual refresh: bfe_rueckliefertarif.refresh_tariffs service.

Adding or updating a utility

1. Find your utility's published 2026+ Rückliefertarif (Tarifblatt PDF, utility website, or VESE pvtarif).
2. Edit tariffs.json:
   • New utility: add a new top-level entry under utilities with name_de, homepage, and a single rates[0] record carrying valid_from: "2026-01-01", valid_to: null, the power_tiers pricing model, and cap_mode (true only for utilities that enforce the StromVV Art. 4 cost-recovery ceiling on producer payments — EKZ, Groupe E, Primeo today).
   • Yearly update for an existing utility: close the prior record's valid_to to the new year start, append a new open-ended record.
3. Bump last_updated to today's ISO date.
4. Validate locally:

   python3 scripts/validate.py        # validates tariffs.json against the schema
   python3 scripts/test_schema.py     # runs schema $def regression tests
   

   Both scripts require jsonschema>=4.18 and exit non-zero on failure.
5. Open a PR.
