Sanity-check a HyperHDR and WLED Ambilight build before adding Rhythm
Get the capture chain, LED mapping, and white-channel behavior stable before treating the TV strip as a normal room light.
A WLED Ambilight build has two jobs: screen-reactive effects and everyday room lighting. Finish the video chain first, then decide how it should appear in Rhythm or Home Assistant as a normal light.
Before you mount the strip
- Verify the HDMI splitter, capture device, and HyperHDR pipeline at the frame rate you expect.
- Test WLED color order, LED count, corners, and power injection on the bench.
- If using RGBW LEDs, tune white-channel handling so white does not look green or blue.
Use Rhythm for non-TV moments
Keep HyperHDR in charge during screen sync. When the TV is off, expose the WLED controller through Home Assistant and let Rhythm return the room to its Day or Sleep lighting state.
