Now got it working with HomeAssistant and esphome with color temp and brightness control.

Trying out Xe drm driver was fun... Not "boring" sadly. Looks like there's still a lot missing. A bunch of stuff including KDE misbehaves weirdly.
Valoren would only update frames if running in the background, however Minetest worked just fine. And anything with OpenCL just crashed.

I didn't realise Harmony OS Next was not Linux. I had a feeling they were moving away from ASOP, but they moved away from Linux as well.
A custom microkernel is an interesting choice.
