I’m using WLED to control some WS2805 on my slat wall project. First photo is the design I’m going with. 2nd photo is how I plan on wiring them up, green square is the controller and connecting each end to the starting point of the following segment. I’ll end up with 12 segments using almost 10 meters. I tested both 5 meter strips using a 12v 10a power supply and didn’t see any issues.

Would I need to inject power using 10 meters?

Does this wiring direction seems correct?

If you have the wall open, I would run power to the far end. You may not need it, but it will at least make the lighting more uniform and leave the option to go brighter.

I have access to the back, it can be wired in anyway.

As I’m looking at this, is it better if I started from the middle using the two shorter strips as the starting point, using GPIO 16 for one and GPIO2 for the second? Would this give me more control of the scenes or is WLED customizable to say if I want the sequence to start from the middle outward or from the two outter edge inward regardless of how I wire them and just segment properly?

For WLED it doesn’t really matter since you can use segments to rearrange the pixels. If you have 1000+ pixels might be a good idea to improve frame rate, but not so likely with WS2805 where you only have 10 or 20 pixels per meter.
