Sonoff M5-1C-80M – Smart Switch with Physical Button, 1 Channel, Matter Protocol, SwitchMan Series (Type 80)

Sonoff M5-1C-80M is a new-generation smart switch, specially designed to fit rectangular wall boxes (type 80/American/Italian). This model is part of the elite certified Matter range, offering universal, instant communication with Apple Home, Google Home, Alexa and SmartThings. With a robust physical button and a minimalist design in the "Starry Grey" shade, the M5-1C-80M turns lighting control into a premium, stable experience that is extremely easy to integrate into any smart ecosystem.

Main Advantages

• Universal Matter Compatibility: Thanks to the Matter protocol, this switch can be added directly to the Apple Home app (or any other compatible platform) simply by scanning the QR code, without depending on external servers or dedicated Sonoff hubs.

• Rectangular Format (Type 80): The design is optimised for installation in rectangular wall boxes, making it the perfect solution for setups where standard round wall boxes are not present, or for horizontal/vertical mounting in multi-gang frames.

• Mechanical Tactile Feedback: The large physical button gives a confirming feel with every press, making it much more reliable and easier to use “blind” than touch panels.

• Adjustable LED Indicator: It has an indicator light whose brightness can be controlled via the app. You can leave it at maximum to find it easily at night, or switch it off completely for total darkness in the bedroom.

• Fast Local Control: As a Matter device, commands are processed locally on your Wi-Fi network, which means an almost instant response time and uninterrupted operation even when the internet is down.

• Certified Safety: The casing is made of flame-retardant polycarbonate (PC V0), offering maximum resistance to fire and high temperatures, protecting the integrity of your home.

Smart Automation Examples

1. Multi-Ecosystem Synchronisation: Thanks to Matter, you can turn on the light from this switch using Siri on an iPhone, while another family member can turn it off using Google Home, all working in perfect harmony.

2. “Peaceful Sleep” Scene: Schedule the light to switch off automatically at a certain time and, at the same time, set the LED indicator to 5% brightness so as not to disturb sleep.

3. Interconnection with Sensors: Set the light to switch on instantly when a Zigbee motion sensor (connected to a Matter hub) detects presence in the hallway.

Package contents: 1 x Sonoff M5-1C-80M smart switch, fixing screws, user manual. (Note: Requires a neutral wire to operate.)

Why choose the Sonoff M5-1C-80M?

If you have rectangular wall boxes and want a future-proof device, Matter certification makes this model the safest investment. It is a blend of modern aesthetics, mechanical reliability and total technological freedom, letting you choose how and with what you control your home, without brand limitations.

Practical use cases

• Replaces a classic switch in a rectangular wall box (type 80), keeping manual control from the physical button, but adding control from Apple Home, Google Home, Alexa or SmartThings via Matter.
• In the bedroom, the LED indicator can be dimmed or turned off from the app, and the light can be switched off automatically at bedtime.
• Integrated into an automation that automatically switches off a light left on when nobody is in the room any more.
