DOMIX – A Modular Open-Source Home Automation System

Hi everyone! I'd like to share DOMIX, a modular DIY home automation system I've been developing and publishing as open-source hardware.

What is DOMIX? DOMIX is a family of custom PCBs designed to cover the most common home automation needs — environmental sensing, energy monitoring, contact inputs, irrigation control, and more — all integrated with ESPHome + Home Assistant via MQTT.

Core architecture Each module runs on ESP32-S3 (or RP2040 for Ethernet-based nodes) and communicates over a shared 8-pole IDC bus with a symmetric pinout. Nodes can use Wi-Fi or wired Ethernet (W5500) for reliability-critical installations.

Happy to discuss the ESPHome YAML design, custom components (ATtiny1616 I²C, display, AC dimmer), or anything else. Feedback welcome!

Hi
That's a very nice idea and concept but closed it's no interest at all :frowning:

Hi Vincèn, what do you mean with closed? It's all on github repository, hardware and software design. Do you need more info about it?

Applying the Creative Commons license to hardware is probably not covering the right set of rights and limitations for hardware designs. I suggest you take a look at the Cern OHL family of licenses
