One thing to check out... is the color order the same?
I might find time tomorrow to try this out.
The color order for Technicolor strings is NOT the same.
Old IP66 TM1804 smart pixel string: RGBOld IP68 TM1804 smart pixel string: RGBNew Ray Wu Technicolor TM1804 string: BGRNew Ray Wu Technicolor WS2811 string: BGRTherefore, you should NOT mix Technicolor pixels with non-Technicolor pixels within the same string. The SSC (and Zeus) can be changed to support one color order, or another... but there is no way to have the color order set in a way that the pixels are consistent -- they simply are not consistent.
Note: this applies not only to patching a string with a pixel, but also appending strings, end-to-end. Use identical color order with each SSC/Zeus.
This info was originally included in the review... nothing has changed, only a reverification.
