How to use

Install the WS558 in accordance with local electrical codes by connecting the live and neutral conductors to the device terminals and securing the unit within a suitable enclosure or wall box. Pair the switch with a compatible wireless gateway or smart home hub following the manufacturer’s pairing procedure. After installation and pairing, use the hub, mobile app, or physical wall switch (if routed through the module) to control the connected load. Ensure power is turned off at the circuit breaker before any wiring work.

Recommendations

Use the WS558 for circuits that do not exceed the rated mains capacity and avoid inductive loads larger than the device specification. Place the module where it will not be exposed to moisture, excessive heat or direct sunlight. For reliable wireless performance, keep a reasonable distance from large metal enclosures and follow the hub’s placement guidelines. If in doubt about wiring or load compatibility, consult a qualified electrician.
