openccu-loom-types 0.1.13

Generated Pydantic / enum types for the openccu-loom REST + WebSocket contract

openccu-loom-types-py

Generated Pydantic models + enum definitions for the openccu-loom REST + WebSocket contract. Sister-repo to the openccu-loom daemon; publishable as openccu-loom-types on PyPI.

What this package provides

• openccu_loom_types.enums — every enum from the daemon's pkg/hmenum. Each enum is a str-typed Python Enum whose values match the wire strings the CCU emits. Source of truth: assets/schemas/enums.json in the openccu-loom repo.
• openccu_loom_types.rest — Pydantic models for the REST surface. Generated from assets/openapi.yaml via datamodel-code-generator.
• openccu_loom_types.ws — Pydantic models for the WebSocket envelope + push payloads. Generated from the same OpenAPI document (the WS envelope schemas live in components.schemas per ADR-0020).

Why this exists (asks.md C1 + C3)

Higher-level clients (py-openccu-loom-client, the future homematicip_local refactor) need stable typed bindings against the daemon. Without a published types package each consumer would duplicate the model code and drift away from the daemon's wire contract. This package is the single import every Python consumer shares — version-pinned and CI-rebuilt on every openccu-loom release.

Regeneration workflow

Set OPENCCU_LOOM_REPO to a local checkout of the daemon repo (default: ../openccu-loom):

# Step 1 — make sure the daemon repo's schema export is fresh:
make -C "$OPENCCU_LOOM_REPO" export-schemas

# Step 2 — regenerate this package's models:
make generate

The two-step split keeps the daemon repo authoritative; this package never re-parses Go source.

Tooling required

• Python >= 3.11
• datamodel-code-generator >= 0.25 (for REST + WS Pydantic models)

Install both with pip install -e '.[dev]'.

Versioning & contract identity

The package version (const.VERSION) is independent of the daemon version; the regeneration workflow bumps the patch number on every daemon release. The daemon coupling is carried by two stamped constants in const.py (written by make generate → scripts/stamp_const.py):

• SCHEMA_DIGEST — canonical digest of the daemon's contract assets these types were generated from (definition: daemon ADR-0028). Clients compare it against GET /api/v1/info.schema_digest to verify exact type/daemon parity at connect time.
• DAEMON_API_VERSION — the daemon's api_version at generation time. Minor bumps add fields without breaking existing consumers; major bumps remove or rename payload fields, scopes, or capabilities — see ADR-0020 in the daemon repo.

Regeneration is automated: the daemon's release workflow fires a repository_dispatch (daemon-release) at this repo; the regenerate-on-daemon-release workflow checks out the daemon at the released tag, regenerates all modules, stamps the constants, bumps the patch version, and opens a PR. Manual fallback: workflow_dispatch with the tag, or the local two-step flow above.

What this package does NOT contain

• HTTP / WebSocket transport — see py-openccu-loom-client (when published) for the higher-level client.
• Any business logic — types only.
• Async helpers — types are framework-neutral.
