Smart mini Wi‑Fi dimmer controller Sonoff MINI‑DIM — compact in‑wall module for LED/lighting dimming, Matter compatible

Sonoff MINI-DIM Matter Smart Mini WiFi Controller/Dimmer

Sonoff MINI-DIM WiFi is an ultra-compact, flush-mounted smart dimmer that turns a regular switch into an advanced smart home system. It offers on/off switching, smooth 0-100% dimming, scenes, schedules, remote and voice control, energy monitoring, and full integration with the Matter over WiFi ecosystem. It fits most installations, supports multiple lighting types, and fits in a standard flush-mounted box. It's a quick way to add "smart" to your existing installation—no need to chisel walls or replace lamps.

Matter and efficient WiFi – one device, all platforms

Thanks to its support for the Matter standard, MINI-DIM works seamlessly with Apple Home, Google Home, Amazon Alexa, SmartThings, and Home Assistant. You don't have to choose one system or worry about compatibility – the module works where you are. At the heart of the device is an energy-efficient ESP32-C3 chip that ensures fast operation, a stable 2.4 GHz WiFi connection, and OTA updates. MINI-DIM can receive new features and improvements with subsequent software versions, keeping it modern for years to come.

Smooth dimming without flickering – light exactly as you want it

The trailing-edge dimming technology used ensures exceptionally smooth brightness control without flickering, humming, or power surges. The light naturally adapts to the situation – strong for work, subtle for relaxation, atmospheric in the evening. Comfort for the eyes and a more pleasant atmosphere in every room. Built-in power measurement allows you to check how much electricity the lighting consumes. This makes it easy to optimize the operation of the lamps, eliminate unnecessary losses, and reduce bills.

Wide compatibility with lamps – install and it works

You don't need to replace light sources or adapt the installation to a specific type of lighting. MINI-DIM works seamlessly with dimmable LEDs up to 200 VA, classic incandescent and halogen bulbs up to 400 W, and dimmable electronic transformers up to 200 W. This means complete flexibility of use – from subtle decorative lighting to powerful main lighting in the living room or kitchen – without compromise or additional costs.

Smart control – app, voice, calibration, and LAN

From the eWeLink app, you can remotely turn the light on and off, adjust the brightness, set schedules, timers, scenes, and automations, and control energy consumption. Voice assistant support allows you to control the lighting with a command – without having to go to the switch. Built-in automatic calibration automatically adjusts the dimming range to the connected lamp, eliminating flickering and dead zones of brightness. In addition, control works locally on the LAN, so the device responds immediately even without internet access – faster, more stable, and whenever you need it.

Robust construction and reliable electronics

The housing made of flame-retardant PC plastic with a V-0 fire resistance rating, combined with high-quality electronic components, guarantees safe and stable operation. A built-in NTC temperature sensor, overheating protection, surge and impact protection effectively protect the installation and connected lighting. CE and RoHS certifications confirm compliance with European safety standards.

Simple installation, quick pairing, immediate effect

Connect the wires, pair the device in the app or via the Matter code, and you're done. MINI-DIM works with both classic wall switches and fully wireless. With dimensions of only 45 × 39.4 × 16.8 mm, MINI-DIM fits easily behind a traditional switch. In just a few minutes, you can turn your traditional lighting into a smart system that improves your everyday comfort.

Included in the set:

• MINI-DIM smart dimmer
• User manual

How to use

Turn off mains power, install the MINI-DIM module into a standard flush-mounted box behind the switch, and connect live, neutral and load wires following the wiring diagram. Restore power, pair the device using the eWeLink app or Matter setup code, then configure brightness, schedules and scenes. Voice assistants and local LAN control can be enabled through the respective platform during setup. Automatic calibration runs when a compatible lamp is connected to optimize dimming range.

Recommendations

Use with dimmable lamps within the specified load limits (LED up to 200 VA, resistive/halogen up to 400 W). Ensure a neutral wire is available and follow local electrical regulations; installation by a qualified electrician is recommended. Place the module indoors in the recommended temperature and humidity range and keep the WiFi router on 2.4 GHz for stable connection.
