OPC UA Server for KC868-A16V3: From Smart Home to Industrial Gateway

[aksurd]

1. Introduction
Hello everyone,
I purchased the KC868-A16V3 controller and was genuinely impressed by its hardware capabilities. To explore its potential beyond smart home applications, I developed a fully functional OPC UA server as a proof-of-concept. This project transforms the A16V3 into a practical industrial OPC UA data gateway.
2. Project Overview & Features
This is a stable, working implementation that demonstrates the controller's ability to serve as an industrial communication node:

• OPC UA Server: Full server implementation based on open62541 and ESP-IDF.
  
• Hardware Support: Utilizes all core I/O of the A16V3:
  • 16 digital input/output channels (via integrated PCF8574).
    
  • 4 analog input (ADC) channels.
    
• Performance: Achieves consistent read times of less than 5ms per tag in testing.
  
• Real-World Validation: Successfully integrated and tested with an industrial SCADA system (Simple SCADA). Screenshots are attached below.
  
• Complete & Open: All source code is available, documented, and ready to be built upon.
  

3. Proof of Concept & Evidence
The project is not a commercial product but a verified and stable proof-of-concept. The screenshots below show the server's data points (tags) being actively read and monitored in a real SCADA client interface, confirming successful integration.

4. Project Goals & Status

• Primary Goal: To demonstrate that affordable, accessible hardware like the KC868-A16V3 can be effectively adapted for standard industrial protocols.
  
• Current Status: Stable proof-of-concept. All core functionalities are implemented, tested, and operational. The code provides a solid foundation for further development, pilot projects, or customization.
  
• Disclaimer: This is an open-source community project, not an official or commercial product from KinCony.
  

5. Repository & Files

• GitHub Repository (Full Source Code): https://github.com/Aksurd/opcua-kincony-a16v3
  
• Direct Download: For users who may have difficulty accessing GitHub, I have attached the complete source code archive
  
  Code:

  forum-release.zip
  to this post. It contains all necessary files to explore and build the project.
  

6. Invitation for Discussion
I welcome all feedback, technical questions, and ideas. I am particularly interested in discussions about:

• Potential improvements for reliability in industrial environments.
  
• Use cases for pilot projects or light automation tasks.
  
• Collaboration possibilities to enhance the ecosystem around KinCony hardware.
  

Thank you to KinCony for the versatile hardware platform, and thank you to the community for your attention.
