Slimme WLAN-wandschakelaar Sonoff M5-3C-80 – 3-voudig, wandgemonteerde slimme schakelaar, model M5-3C-80

Sonoff M5-3C-80 is a Wi‑Fi smart wall switch designed for installation in a standard wall box or in the Sonoff M-80 frame-holder (holder sold separately). The M5-3C-80 provides three independent mechanical channels for controlling lights or other AC loads and supports local and remote control via the eWeLink app, voice assistants and LAN. It works on 2.4 GHz Wi‑Fi and is compatible with Sonoff ecosystem devices such as NSPanel, R5 scene controller and DW2-WiFi sensors.

Advantages

The smart wall switch offers three quick-response mechanical buttons with adjustable LED indicators for easy detection in darkness and ergonomic operation even when wearing gloves. It supports full Sonoff functionality — timers, scenes, device grouping, status sync and sharing — and can operate without cloud access when local LAN is configured. The compact modern design matches other Sonoff products and fits standard wall installations.

Suitable for

• Controlling multiple lights from a single wall location

How to use

Connect the live and neutral wires and the individual output lines for each channel following local electrical codes and the product wiring diagram.

After setup, control each gang by pressing the mechanical buttons, via the eWeLink app, by voice through a linked assistant, or by scenes and schedules configured in the app.

Recommendations

For reliable operation, use on a stable 2.4 GHz Wi‑Fi network and avoid connecting loads exceeding the per-gang ratings. If multi-way control is required, pair with Sonoff Scene Controller R5 and follow wiring instructions to implement two-way or multi-way circuits. Ensure installation is performed by a qualified electrician according to local regulations.
