Update:

I went ahead and cut the last pixel off of the first drop. Drop was 6 pixels long so now it’s 5.

  • Test 1: Connected the 6th cut off pixel to controller and told WLED there was 1 pixel. It lit.

  • Test 2: Connected icicle string to controller and set WLED to 5. First drop lit. Set it to 6 first drop (remember there are only 5 pixels there now) still lit. Set to 7, first drop lit and first pixel of second drop lit.

  • Test 3: connected icicles and connected Argb fairy string to where I cut the pixel off. Set WLED to 6, First drop and 1 pixel on fairy string light. Set to 7 and first drop, 2 pixels on fairy string light AND first pixel on second drop light. Set it to 8, First drop and 3 pixels on fairy string light AND first 2 on second drop light.

Mystery solved!

It looks like the first pixel of each drop is a fixed/hard coded one and the ones below it are regular addressable pixels. Test 1; supports this.

The interesting thing here is that the hard coded pixel must still be passing on the data to the addressable pixels below it and also letting them know to take the address after it’s hard coded one.

So as long as the first pixel of every drop is good you can replace any of the other pixels if they fail, with an addressable one.

:yawning_face: glad that’s over lol.
