aiohomematic
Homematic interface for Home Assistant running on Python 3.
Decision gist · record as of 2026-08-14
Yes. The library is actively maintained (release 4 days old), has no known vulnerabilities, uses a permissive MIT license, and requires only four lightweight runtime dependencies. It is marked Production/Stable and powers a real Home Assistant integration. Install it if you need to control Homematic devices from Python; the only constraint is a requirement for Python 3.14 or later and network access to a compatible Homematic backend.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.14 or later; requires network access to a Homematic CCU, OpenCCU, Homegear, CUxD, or CCU-Jack device.
- Low friction install with four runtime dependencies (aiohttp, openccu-data, pydantic, python-slugify).
- Active maintenance with a release 4 days old and recent commits; marked Production/Stable with 167 repository stars.

What it is and what it does
aiohomematic is a modern async Python library that abstracts the Homematic protocol stack, allowing you to discover, control, and monitor Homematic and HomematicIP devices connected to a CCU hub or compatible backend. It replaces the older pyhomematic project with automatic entity discovery, fewer manual device definitions, and faster startup times. The library handles connection management, event routing through a unified EventBus, protocol translation (XML-RPC for standard interfaces, JSON-RPC for CUxD/CCU-Jack), and caching of device descriptions and paramsets.
The library is built on asyncio and fully typed (mypy strict mode), making it suitable for integration into larger async applications—most notably as the backend for the Home Assistant "Homematic(IP) Local" integration. It supports extensible entity classes for complex device types (climate, cover, light, lock, siren, valve), hub entities for CCU programs and system variables, and robust operation through circuit breaker patterns, command retry/throttling, and automatic reconnection after CCU restarts.
Use it for
- Build a Home Assistant integration or custom automation platform that controls Homematic devices without polling.
- Monitor Homematic device state and respond to events in real-time via the EventBus in a standalone Python application.
- Integrate Homematic climate, lighting, or lock devices into a broader home automation system using async/await patterns.
- Manage CCU programs, system variables, and inbox messages programmatically alongside device control.
- Test Homematic protocol implementations using pydevccu without requiring physical hardware.
