Sonoff M5-3C-80M – Triple Smart Switch with Physical Buttons, 3 Channels, Matter Protocol, SwitchMan Series (Type 80)

Sonoff M5-3C-80M is the top of the range in the SwitchMan series for rectangular wall boxes (120/80 standard), offering independent control of three electrical circuits from a single elegant panel. This model is Matter certified, which means it removes the barriers between brands: you can add it directly to Apple Home, Google Home or Alexa by scanning a simple QR code. With three physical buttons with excellent tactile feedback and a modern "Starry Grey" finish, it is the ultimate solution for managing complex lighting in a compact, "future-proof" format.

Main Advantages (Selling Points)

• Native Matter Certification: Matter ensures smooth integration into any smart ecosystem. The device communicates locally on your network, offering instant response times and superior data security, without relying solely on the manufacturer's cloud.

• Triple Control in a Single Wall Box: Ideal for rooms with complex lighting scenarios (e.g. a living room with a chandelier, spotlights and ambient lights). You manage three different zones without needing several wall boxes or switches on the wall.

• Rectangular Format (Type 80/120): Designed specifically for installation in rectangular wall boxes, offering perfect aesthetic coverage and a professional look, and very popular in modern interior design layouts.

• Short-Travel Physical Buttons: Unlike touch panels, which can be hard to operate with wet hands or without looking, the mechanical buttons of the M5 series offer clear tactile confirmation and long-term reliability.

• LED Indicator with Adjustable Brightness: You can adjust the brightness of the LED indicator on each button via the eWeLink app. It can be set to a discreet mode for the bedroom or switched off completely so as not to disturb sleep.

• Flame-Retardant PC V0 Materials: Safety comes first. The fire-resistant housing and a design that allows heat dissipation ensure stable and safe operation even at maximum load.

Smart Automation Examples

1. “Cinema” Scene: Configure a button so that a long press turns off all 3 lighting channels and switches on the television or projector at the same time (via a smart scene).

2. Centralised Control via Matter: Use one channel to control the physically connected light, and the other two channels to activate devices from other manufacturers via Matter (e.g. blinds or air purifiers).

3. Holiday Lighting: Schedule the 3 circuits to switch on and off at different times during the night to simulate presence in the house while you are away.
