Integrating Arduino Sensors with KNX: A Community Collaboration

General
1

I’ve been exploring the integration of an Arduino sensor network with my KNX home automation system, and I’m excited to share my progress and seek your insights. Here’s my current setup:

  1. Raspberry Pi as the Vera Server: I’m using a Raspberry Pi to act as the Vera server, leveraging Henrik’s Lua plugin. This allows me to override the luup object and integrate my sensors seamlessly.

  2. Linknx Integration: Linknx is running on the same Raspberry Pi, managing the KNX communication. The Lua script pushes sensor values to specific group addresses in the KNX network, formatted as prefix/radioId/childId.

  3. Rule Creation and Administration: Through knxweb/knxweb2, I can create and manage rules, which is incredibly handy for automating various home functions based on sensor data.

I’m considering releasing this KNX Lua extension as open source, alongside Henrik’s existing code, to benefit the broader community. However, I’d love to hear your thoughts on potential improvements or alternative approaches. Have any of you successfully integrated Arduino sensors with KNX? What challenges did you encounter, and how did you overcome them?

This project has been a fantastic learning experience, and I’m eager to collaborate with others who share my enthusiasm for DIY home automation. Let’s continue to innovate together!

Best regards,
Johan
