aiohomematic-config

What it is and what it does

aiohomematic-config is a presentation-layer library that bridges Homematic device configuration data and UI rendering. It takes paramset descriptions and current device values from aiohomematic, then generates Pydantic-backed form schemas optimized for display in a configuration UI. The library handles grouping flat parameter lists into logical sections, mapping technical parameter IDs to human-readable labels, and selecting appropriate widget types for each parameter.

The package operates purely on data structures—it does not communicate with a CCU or make RPC calls. It includes components for schema generation, parameter grouping, label resolution, change tracking with undo/redo support, and configuration serialization. Output is JSON-serializable Pydantic models, making it straightforward to send schemas to a frontend or API consumer.

Use it for:

• Generate form schemas for a Homematic device configuration web UI from paramset metadata and current values.
• Map device parameter types to appropriate UI widgets (dropdown, text input, slider, etc.) automatically.
• Group flat parameter lists into logical sections for better UX in device configuration interfaces.
• Track configuration changes with undo/redo and dirty-state detection during a user's editing session.
• Serialize and deserialize device configurations for storage or transmission between systems.

Worth the install?

AI-flagged interpretation of the facts on this page — verify before relying

Transforms Homematic device paramset descriptions into UI-ready form schemas using Pydantic models, without requiring RPC or CCU access.

Yes, if you are building a Homematic device configuration UI and need to transform paramset data into form schemas. The low install friction, active maintenance, and permissive MIT license make it a straightforward choice. Be aware it is in early alpha (API may shift) and requires Python 3.14, which is not yet widely deployed—verify your target environment supports it before committing.

Install

aiohomematic-config on PyPI

pip install aiohomematic-config

uv add aiohomematic-config

poetry add aiohomematic-config

Installing aiohomematic-config

Before you install

Low install friction; pure Python wheel with three runtime dependencies. Active maintenance with recent release (13 days old) and passing test suite. Early alpha status (Development Status :: 3) means the API may shift.

License in practice

MIT License permits commercial and private use with minimal restrictions; you must retain the license notice in distributions.

Quickstart

from aiohomematic_config import FormSchemaGenerator

generator = FormSchemaGenerator(locale="en")
schema = generator.generate(
    descriptions=descriptions,
    current_values=current_values,
    channel_type="HEATING_CLIMATECONTROL_TRANSCEIVER",
)
print(schema.model_dump_json(indent=2))

Requires Python 3.14 or later (capped_below_current); aiohomematic and openccu-data must be installed first.

Verify before relying

• Whether the package supports locales beyond English and German despite declaring both in classifiers.
• What the undo/redo and dirty-state tracking in ConfigSession actually persist to or whether they are in-memory only.
• Whether FormSchemaGenerator's output is compatible with common web form frameworks or if it requires custom rendering.
