One lighting scene for your PC and your room. The RGB inside the case and the lights on the wall, driven by a single effect engine: colours flow from the RAM through the strip onto the wall.

profiles
Gaming, work, night: each keeps its effect, colours and which devices are on. Switch from the tray, the phone or a hotkey.
screen ambilight
The lights follow what is on the screen: strips around the edges, a Nanoleaf wall as a mosaic. About 0.1% of an 8-core CPU.
control from your phone
Scan a QR code and the same interface opens on your phone, over your home network only. Shortcuts and scripts can send commands too.
describe a mood
Type “sunset on the beach” and a local language model picks the colours, effect and speed. Runs offline through Ollama.
works like a light switch
Off in the app means really off. When the PC sleeps or shuts down, the room goes dark, or keeps its own state, as you choose.

Nanoleaf Blocks and AiDot bulbs are verified on real hardware; the rest are tested against simulators. Own one of them? Reports on GitHub help a lot.
download
Get haku-control-setup.exe from the latest GitHub release and run it.
allow admin rights
The app talks to the motherboard and memory, so it starts at sign-in through an elevated task.
light it up
It sits in the tray. On first start a short guide shows what was found and scans the network for lights.
Needs Windows 10/11 x64 and the WebView2 Runtime (built into Windows 11). Memory lighting needs PawnIO ↗. Updates install themselves, settings are kept.
