Use the IKEA BILRESA scroll wheel (Matter/Thread) as a smooth dimmer for any HA light. Slow rotation = fine adjustment. Fast spin = rapid sweep. Direction-locked, no bounce.
The BILRESA is a Matter Switch cluster device (Thread SED, 9 endpoints across 3 modes).
Mode 2 exposes EP4 (CW) and EP5 (CCW) as scroll endpoints with FeatureMap=22
(MS + MSR + MSM), MultiPressMax=18, ActionSwitch NOT set.
