If your bathroom occupancy switch turns on from hallway traffic, the problem is usually an open door creating a line-of-sight slice. Use a quick walk test, then aim or mask the sensor so it catches the first step in but ignores pass-bys.

Older homes often lack a neutral in the wall box, and that wiring reality determines whether a PIR sensor switch will be stable or glitchy with LEDs. This guide explains what to check, why no-neutral switches misbehave, safer alternatives, and what to avoid.

Make multi-location stair lighting feel like a normal 3-way using Rayzeek PIR switches. Learn placement, the one-decider principle, safe timeout tuning, and a walk-test protocol that prevents flicker and mid-stair darkness.

LEDs that glow when off, flicker at timeout, or shut off “randomly” usually aren’t a bad switch. This field guide shows how to name the symptom, run one-change tests, and match the fix to drivers, heat, load, or false triggers.

Conference rooms can pass a walk test and still go dark mid-call when people sit still. Learn a practical control contract—often vacancy mode—plus validation steps for seated presence, sensor placement, and timeouts that keep video meetings reliable without making rooms always-on.

Fitting rooms fail in two ways: lights that shut off mid-change or never shut off at all. Learn a practical trigger-hold-release approach, plus a 10-minute per-room checklist and humane settings that prevent both outcomes.
