๐Ÿ“Œ Overview

DOMIX is an open-source modular home automation system that integrates the core controller and I/O modules within a centralized control cabinet, and unifies buttons, switches, door sensors, relays, valves, and environmental sensors in the home into a single structure. Rather than scattering individual Wi-Fi devices like a typical DIY smart home setup, it aims for a structurally manageable approach by combining DIN rail-mounted hardware, wired Ethernet, I2C expansion, and an RS485 sensor network. Both the Hackster introduction and the GitHub README describe this project as an open system characterized by โ€œno cloud, no vendor lock-in.โ€

๐Ÿ“Œ Features

Modular DIN Rail Structure

It is based on a system where expansion modules M2โ€“M9 are added as needed around the M1 core. Functions that are not installed can be excluded, allowing flexible configuration ranging from simple relay control to energy metering, sprinklers, and I/O expansion.

Wired Ethernet-Centric Design

The M1 core uses W5500-based 10/100 Ethernet. The README explicitly states โ€œEthernet first,โ€ and handles MQTT, OTA updates, and ESPHome integration over a wired network. The design prioritizes reliability and maintainability over wireless instability.

Separated Sensor Network Architecture

Indoor sensor nodes are separated into the RP2040-based S series, communicating with the M1 via RS485/Modbus RTU. In other words, cabinet-level control and distributed indoor sensors are separated by role, improving scalability and wiring stability.

Open-Source Ecosystem Compatibility

It officially supports integration with Home Assistant, Node-RED, OpenHAB, and MQTT platforms. The GitHub repository also includes BOM, 3D print files, software, and circuit documentation, ensuring high reproducibility and learning value.

High System Integration Relative to Cost

According to the Hackster description, the total system BOM is estimated at around โ‚ฌ420. Compared to commercial building automation systems, it is low-cost, and offers a more structured control configuration than typical DIY setups. However, this figure is provided by the author and has not been validated as a mass-production cost.

๐Ÿ“Œ System Architecture

๐Ÿ“Œ System Architecture
๐Ÿ“Œ System Architecture

 

Central Control Unit (M1)

  • The ESP32-S3 operates as the main application processor, managing the W5500 Ethernet controller, CC2652-based Zigbee module, MAX13487E RS485 transceiver, and the IยฒC expansion bus together.
๐Ÿ“Œ System Architecture
๐Ÿ“Œ System Architecture
๐Ÿ“Œ System Architecture
  • The M1 module uses the ESP32-S3 and W5500.

The ESP32-S3 was selected because it is well-suited as a central application processor that must integrate and control Ethernet, Zigbee, RS485, and IยฒC, thanks to its sufficient processing performance and support for various interfaces.

The W5500 was adopted to reduce the communication load on the MCU through its hardware TCP/IP stack and to provide a more stable wired network environment compared to Wi-Fi, thereby ensuring the reliability and real-time performance of the smart home control system.

Internal Module Connections

  • Modules M2โ€“M9 are connected to M1 via a multidrop IยฒC bus. The documentation clearly defines bus arbitration rules to avoid address conflicts, and in expansion boards, the bus is further extended using TCA9548A-series IยฒC switches.

External Platform Integration Flow

  • Upper-level systems connect to M1 via Ethernet, and M1 exposes its status through MQTT, Home Assistant, Zigbee2MQTT, and a web interface. The documentation also considers MQTT and Home Assistant auto-discovery features.

Sensor Expansion Flow

  • The S-series room sensors are built as RP2040-based nodes and connect to M1 via RS485/Modbus RTU. In other words, cabinet internal modules use IยฒC, while room sensors use RS485, separating roles by communication method.

Data Flow Summary

  • External platforms/sensors/wireless devices โ†’ M1 (Ethernet, Zigbee, RS485) โ†’ internal IยฒC module control โ†’ status/data collection โ†’ re-exposed via MQTT, Home Assistant, OpenHAB, etc.
  • This design aligns with the documentationโ€™s description of โ€œcentralized intelligence + function-specific distributed modules.โ€

๐Ÿ“Œ Role and Application of the WIZnet's Chip

Chip Model Used: W5500

Role in the Network

  • In the DOMIX M1 core, the W5500 is responsible for the wired Ethernet interface.
  • Through this Ethernet link, MQTT communication, native integration based on ESPHome, OTA updates, and local network access are handled.

Why the W5500 is Important

๐Ÿ“Œ Role and Application of the WIZnet's Chip
  • This project places a core value on an always-connected wired network instead of the instability of Wi-Fi-based DIY smart homes. The README also declares โ€œEthernet first, always,โ€ indicating that the W5500 is not just a simple component but a key element that embodies the design philosophy of the project.

Technical Advantages

  • By applying the W5500, an ESP32-S3-based system can be relatively easily connected to a 10/100 wired network, securing the stable network backbone required for a cabinet-based control system.
  • Especially in a structure like this projectโ€”where MQTT, Home Assistant, OTA, and remote diagnostics are all considered simultaneouslyโ€”the use of the W5500 goes beyond simply โ€œreplacing Wi-Fiโ€ and functions as a means of ensuring overall system reliability. This demonstrates that WIZnet chips can be used not just for simple TCP server examples, but as a structural smart home backbone.

๐Ÿ“Œ Market & Application Value

Applicable Markets and Industries

  • The most direct markets include residential smart homes, small building automation, custom electrical cabinet manufacturing, and advanced DIY automation for makers and prosumers.
  • In terms of functionality, it covers lighting, shutters, contact monitoring, energy metering, sprinklers, and indoor air quality and occupancy detection, making it applicable to small commercial spaces and technology-oriented housing projects.

Market Evaluation

  • It is more suitable for a B2B-adjacent market or a professionally installed prosumer segment rather than mass-market B2C products.
  • The actual buyers are more likely to be smart home integrators, electrical panel manufacturers, advanced home lab users, and small automation solution providers rather than general consumers. This assessment is based on expert interpretation of the system complexity and wiring structure described in the available materials.

Competitiveness

  • Compared to commercial systems such as KNX or PLC, its advantages include lower entry cost, open-source nature, and high customizability.
  • On the other hand, compared to Zigbee/Wi-Fi-based DIY setups, it offers advantages in centralized architecture, ease of maintenance, clear wiring structure, and modular expandability. While this structural differentiation is clear, it has weaknesses in certification, installation responsibility, and compliance with safety regulations compared to commercial products.

Productization Potential

  • Structurally, it has strong potential for product development. The BOM, 3D files, schematics, and firmware are publicly available, and the modular design is well-organized.
  • However, the author explicitly states in the README โ€œnot certified for production useโ€ and on Hackster โ€œThis is not a product. It's a research platform.โ€ Therefore, at its current stage, it is closer to an advanced research and experimental platform than a commercial product.

๐Ÿ“Œ External Indicators

GitHub (Link)

  • Based on the public repository, it has 5 stars, 0 forks, 0 issues, 0 pull requests, and 242 commits. This indicates that it has not yet reached a stage of broad external adoption, but it does show that it is not a short-term, neatly packaged project, and that a substantial amount of development has actually been accumulated.

Hackster (Link)

  • The Hackster project page shows 1,500 views and 0 comments. Since the posting date is very recent (April 9, 2026), these figures should be considered an initial response. In other words, there has been some incoming interest right after publication, but it has not yet expanded to active discussion or engagement.

YouTube (Link)

  • The YouTube video appears to be technical reference content focused on the process of building the DOMIX system from scratch. While quantitative metrics such as views, likes, and comments are not clearly confirmed at this time, it emphasizes a โ€œfrom scratchโ€ build process, indicating that it is intended more for learning and implementation reference rather than general promotion. Therefore, it is likely to have long-term value within ESPHome, Home Assistant, and DIY automation communities, rather than achieving short-term mass adoption.

OSHWLab (Link)

๐Ÿ“Œ External Indicators
  • DOMIX is a project with schematics and PCB designs publicly available on OSHWLab, featuring a structure completed to a level of actually manufacturable hardware. While quantitative metrics such as likes, views, and clones are not currently confirmed based on available data, the nature of the platform provides a practical foundation for design reuse and manufacturing. This goes beyond simple idea sharing and can be evaluated as an open hardware reference project with reproducibility and scalability.

๐Ÿ“Œ WIZnet Strategic Value

Implications from the WIZnet Maker Ecosystem Perspective

  • DOMIX demonstrates that WIZnet chips are not just simple network connectivity components, but can serve as the core wired backbone of a smart home control cabinet.
  • In particular, it is significant that the W5500 is used not as a standalone DIY board, but as the central communication interface in a cabinet-based control system.

Message to Other Customers and Developers

  • It conveys the message that โ€œWIZnet is well-suited for building structured wired IoT systems in environments where Wi-Fi is unstable or difficult to maintain.โ€
  • Additionally, as a real-world use case integrated with Home Assistant, MQTT, Zigbee, and RS485, it serves as a strong reference for proposing WIZnet products in field automation, building control, and sensor gateway applications.

Potential for Expansion into Similar Projects

  • This architecture can be extended beyond residential automation to small factory auxiliary control panels, server room environmental monitoring, remote facility I/O aggregation, and agricultural or irrigation control systems.
  • In fact, the inclusion of energy metering and sprinkler control in the DOMIX module lineup suggests a broad application range for WIZnet-based wired control
