Hey @Sargon151!
Ha, this file extension makes me laugh every time I see it as well. It actually stands for Signed Transfer Firmware Update.
Wizard will likely include WS2814 support in an upcoming release. Based on historical release cycles, I’d estimate 1-3 months.
From what I’ve read on the forums and my discussions with Wizard, the company is concerned about the cost of supporting people experiencing problems on clones or forks, as well as the ongoing commercial viability (and quality). I watched this tragedy happen to the ArduPilot boards.
He’s talked about licensing before here.
You can see the list of components and peripherals that are open-source on the github readme. It includes the open source drivers he’s released for the three major pixel protocols. In fact, I think I see some color order and hasWhite stuff in the WS281X adapter (also see this line), though my C++ is not strong enough to look through this and know if someone could essentially contribute WS2814 support.
