Controlling WLED via KNX, Home Assistant, and direct audio input
Hi everyone,
This might be a newbie question, but I want to do a quick sanity check to make sure I’ve understood everything correctly before buying the rest of the hardware and flashing firmwares.
Here is what I'm trying to achieve:
- Control WLED (probably QuinLED DigQuad) using physical KNX wall switches.
- Integrate with Home Assistant via a KNX-IP interface for smart automations and dashboards.
- Audio reactivity: Make the addressable LEDs react to music from my multi-room audio setup (WiiM streamers).
KNX integration: To make the QuinLED controller act as a native KNX device, would i need to flash OpenKNX firmware onto it and use an OpenKNX UP1-UART module connected to the board? Or is this possible using WLED with KNX-IP?
Audio input: To feed a physical line-in audio signal (3.5mm / RCA) directly from my WiiM streamer into the WLED controller, I need an I2S ADC module (like a PCM1808 or WM8960) wired to the ESP32’s I2S pins, right?
For audio reactivity across multiple rooms, would you recommend feeding line-in via an I2S ADC directly into the DigQuad, or running LedFX on Home Assistant and streaming DDP data over Ethernet instead?
If I control DigQuad through KNX commands over UP1-UART, do I lose the ability to push DDP data over ethernet from Home Assistant server?
Probably the easiest way would be to send KNX signals to Home Assistant server, and just let HASS command WLED. But I don't want the basic functionality of my led strips to rely on the HASS server running 24/7.
Would love to hear your thoughts or info about similar KNX + WLED + Audio setups!
Thanks!
