How do I install RedMatic on my CCU3?

Download the tar.gz file from the releases page and install it via the Homematic web UI under Systemsteuerung -> Zusatzsoftware, then reboot the CCU. Be patient as it can take up to 10 minutes to complete.

Can RedMatic work with Zigbee devices?

Yes, using the node-red-contrib-zigbee node, you can integrate Zigbee devices like Xiaomi Aqara or Philips Hue via a USB interface, as documented in the wiki.

RedMatic vs Home Assistant for Homematic automation?

RedMatic is a Node-RED-based addon specifically for Homematic controllers, offering visual programming and tight integration, while Home Assistant is a more general-purpose platform that runs on various hardware with a broader ecosystem.

How to backup my RedMatic flows?

Use the flow export feature in Node-RED or refer to the Backup section in the documentation for steps on saving configurations to prevent data loss.

Is RedMatic compatible with CCU2?

No, RedMatic is only designed for CCU3, piVCCU3, and specific RaspberryMatic variants, not for CCU1 or CCU2, as explicitly stated in the prerequisites.

How to set up MQTT integration with RedMatic?

Use the included MQTT node to connect to a broker with configurable topic and payload structures; examples are provided in the Flow MQTT documentation for easy setup.

What is RedMatic?

RedMatic is a packaged version of Node-RED designed as an addon for Homematic CCU3 and RaspberryMatic smart home controllers. It enables visual, code-free automation of Homematic devices and integrates with a wide range of external systems and services. The project solves the need for a powerful, user-friendly automation hub that runs directly on existing Homematic hardware without requiring additional servers.

Target Audience

Homematic CCU3 or RaspberryMatic users who want to create advanced automations without deep programming knowledge, and smart home enthusiasts seeking an extensible, self-hosted automation platform with HomeKit support.

Value Proposition

Developers choose RedMatic because it combines the flexibility of Node-RED with seamless Homematic integration, offering a ready-to-use package with pre-configured interfaces and HomeKit support. Its extensive node library and community-driven ecosystem provide unparalleled integration possibilities while running efficiently on existing hardware.

Use Cases

Best For

Creating visual automations for Homematic devices without writing code
Integrating Homematic systems with Apple HomeKit and Siri
Building custom dashboards for smart home monitoring and control
Connecting Homematic CCU to MQTT brokers for data exchange
Extending smart home functionality with community nodes (e.g., Zigbee, KNX, voice assistants)
Replacing or supplementing CCU's Rega logic with more capable automation

Not Ideal For

Projects using older Homematic hardware like CCU1 or CCU2, as RedMatic requires CCU3 or specific RaspberryMatic versions
Environments needing a standalone, hardware-agnostic automation server, since RedMatic is tightly coupled with Homematic controllers
Systems where visual programming is a drawback, such as teams with strong programming skills preferring code-based automation over Node-RED flows
High-scale automations with heavy resource usage, due to potential performance constraints on CCU hardware

Pros & Cons

Pros

Easy Installation

Can be installed via the CCU web UI without Linux skills or editing configuration files, as stated in the README, making it accessible for non-technical users.

Integrated HomeKit Support

Includes RedMatic HomeKit for seamless Apple HomeKit integration of Homematic devices and other systems without additional setup, as highlighted in the features.

Extensive Integration Options

Leverages Node-RED's library of thousands of community nodes for connecting to services like KNX, Xiaomi, databases, and voice assistants, enabling broad smart home expansion.

Visual Automation Interface

Provides drag-and-drop Node-RED flows for creating rules and automations with minimal programming knowledge, based on the project's core use of Node-RED.

Cons

Hardware Dependency

Only compatible with CCU3 and specific RaspberryMatic variants, excluding older models like CCU1 and CCU2, which limits adoption for users with existing hardware.

Long Installation Time

The README notes that installation can take up to ~10 minutes, which might be slow for users expecting a quick setup process.

Community Node Reliability

Relies on community-maintained nodes which may vary in quality and support, potentially leading to integration issues or broken functionality over time.

Open Source Alternative To

RedMatic is an open-source alternative to the following products:

ioBroker

ioBroker is an open-source IoT platform written in JavaScript that integrates and automates various smart home devices and services through a central administration interface.

Homebridge

Homebridge is a lightweight Node.js server that emulates the iOS HomeKit API, allowing non-HomeKit enabled smart home devices to be controlled via Apple's Home app and Siri.

Home Assistant

Home Assistant is an open-source home automation platform that allows local control and automation of smart home devices, with a focus on privacy and local execution.
