below picture shows how WIImote receiver and 3-point IR led work
Since Steam Client's Update 2022-09-21, Steam detects Wiimotes and takes full control over it, which makes Opentrack not detect it as a real Wiimote anymore: You need to set it on Steam's blacklist.
I have to make a rack to stick WIImote with monitor.
as solution 2 is better for me, because solution 2 can keep good distance between my hat and WIImote. and solution 1 is too close to my hat
