I am using the FLS-M LED controller with a BTF-LIGHTING WS2811 Dual IC RGBCCT FCOB COB LED Strip (140 segments). The strip features an interleaved design, with odd ICs controlling RGB segments and even ICs managing WW (warm white) and CW (cool white) segments. This configuration causes compatibility issues: in continuous segments (e.g., 0-140), setting red activates both RGB red and CW, green engages WW, and blue operates without interference.
To demonstrate, I have tested two approaches in the Config-Builder. The first uses individual lights at odd positions (e.g., 1, 3, 5, 7, 9), achieving pure RGB separation without WW/CW activation, as shown in the attached “Odd Segments Configuration - Pure RGB” (screenshot and output).
In contrast, continuous segments (e.g., Layer 1: 1-34 green; Layer 2: 30-90; Layer 1: 70-139 orange/green) result in unintended WW/CW illumination, visible as white interference in the gradient, per the attached “Continuous Segments Configuration - With WW/CW Interference” (screenshot and output).
The manufacturer presumably selected WS2811 for its cost-effectiveness relative to options like WS2805 and its three-wire simplicity. I propose firmware and Config-Builder enhancements, such as an interleaved IC mapping mode, to support independent RGB and WW/CW control — either as a new driver “Dual WS2811 (RGB WW/CW)”, or as an option to turn on interleaving for odd and even segments.
Drawing from my electronics engineering background and expertise in embedded systems, I am available to collaborate or testing.
