Wall switch dimmer Sonoff MINI-DIM-E — smart WiFi in-wall dimmer switch for LED and incandescent loads

Sonoff MINI-DIM-E is a compact in-wall WiFi dimmer and smart switch designed to control lighting loads such as dimmable LED and incandescent lamps. Built to fit behind a standard wall plate, this module enables remote on/off control, smooth brightness adjustment from 0 to 100%, scheduling and integration with Matter-compatible smart home systems. The device includes automatic calibration for the connected load, energy monitoring and built-in protections to improve operational safety and reliability.

Advantages

MINI-DIM-E provides smooth trailing-edge dimming for wide compatibility with modern light sources and reduced flicker. It supports Matter for unified integration with platforms such as Apple Home, Google Home, Amazon Alexa and Home Assistant (a compatible Matter hub is required). The unit offers built-in power measurement for basic energy monitoring, schedule and scene support, voice control, automatic load calibration and protections against overheating and surges. Its compact form factor fits common European wall boxes for straightforward installation.

Suitable for

• Wall-mounted control of dimmable LED bulbs in living rooms and bedrooms
• Replacing standard switches to add remote dimming and scheduling
• Integration into Matter-based smart home scenes and automations
• Energy-aware lighting control where basic power monitoring is useful

Key specifications

• Compatibility: Dimmable LEDs, incandescent and halogen lamps, dimmable electronic transformers (not for fluorescent lamps, LED strips or inductive loads)
• Load capacity: up to 200 VA for dimmable LED bulbs and electronic transformers, up to 400 W for incandescent/halogen
• Dimming range: 0–100% with trailing-edge dimming
• Connectivity: Wi‑Fi IEEE 802.11b/g/n 2.4 GHz; Matter over Wi‑Fi support (requires compatible Matter hub for ecosystem integrations)
• Power measurement: built-in real-time energy consumption monitoring
• Rated voltage: 220–240 V ~ 50 Hz
• Operating temperature: -10 °C to 40 °C
• Housing material: flame-retardant PC; fits 86-type and 60 mm round European boxes
• Protections: overheat protection and surge protection

How to use

Install the MINI-DIM-E module behind a wall plate inside a compatible 86-type or 60 mm round box following local electrical regulations and ensuring power is switched off during installation. Connect the live, neutral and load terminals as indicated in the user manual, then restore power. Pair the device with your Matter-compatible hub or configure it via the vendor app for Wi‑Fi setup; once added, set brightness levels, schedules and scenes through the app or voice assistant. Use the automatic calibration function after connection to optimise dimming performance for the attached lamp.

Usage recommendations

Use MINI-DIM-E with dimmable lamps within the specified load ranges and avoid fluorescent tubes, LED strips and inductive loads. Ensure a compatible Matter hub is available for Matter ecosystem features and verify wiring is performed by a qualified person if you are not familiar with in-wall electrical work. For stable Wi‑Fi operation, place the hub or router within reliable range of the installation point.
