Sonoff SwitchMan M5-2C-120W – 2-Channel Smart Switch with Physical Buttons and Wi-Fi Control

The Sonoff M5-2C-120W is a two-channel smart switch from the SwitchMan series, designed to offer modern, refined control over the lighting in your home. This model is equipped with high-precision physical buttons that provide excellent tactile feedback, combined with advanced smart features accessible through the eWeLink app. Its design is adapted for type 120 wall boxes (a standard often used in certain regions or for specific wall installations).

Main Advantages (Selling Points)

• Dual Control with Physical Buttons: Unlike touch models, the M5-2C features robust mechanical buttons, ideal for users who prefer the classic feel of pressing a switch but want all the benefits of a smart home. The two channels allow two lighting circuits to be controlled separately from a single unit.

• Adjustable LED Indicator: The indicator light on the buttons helps you find the switch in the dark. Its brightness can be adjusted from the app so it does not disturb your sleep, making it ideal for bedrooms.

• Remote Control and Voice Commands: Manage the lights from anywhere via the eWeLink app or by voice command using Amazon Alexa, Google Assistant or Siri Shortcuts. It is the perfect solution for those moments when you leave home and are not sure whether you turned the lights off.

• Smart Automations and Scenes: You can create schedules, timers or complex scenes. For example, you can set the lights to turn on automatically at sunset or to all switch off with a single press when you leave home.

• Compatibility with "eWeLink-Remote": The M5-2C can be used together with the S-MATE wall remote or the R5 buttons, allowing the lights to be controlled from several points (virtual two-way switching), with no need for extra wiring between switches.

Installation and Safety

• Requires a Neutral Wire: For stable operation and permanent Wi-Fi communication, this device requires both wires to be connected: Live and Neutral.

• Certification and Protection: Made from flame-retardant materials (PC V0), the switch is designed to withstand high temperatures and provide safe long-term use on the home's electrical network.
