SONOFF MINI-2GS MINI DUO - Matter Wi-Fi Dual Channel Smart Switch 16A

SONOFF MINI-2GS MINI DUO - Dual Channel Connected Switch Matter Wi-Fi 16A

GENERAL OVERVIEW

The MINI DUO (MINI-2GS) is an ultra-compact dual channel smart switch from the SONOFF MINI Extreme series. With its reduced dimensions of only 45×39.4×16.8mm and weighing 36.5g, this micro-module easily fits into any standard flush-mounted box, even the most compact ones.

Based on the Matter over Wi-Fi protocol, this switch offers universal compatibility with all major home automation ecosystems on the market: Apple Home, Google Home, Amazon Alexa, Samsung SmartThings, Home Assistant, and any Matter certified platform. This interoperability ensures seamless integration into your existing setup, regardless of your preferred platform.

The MINI-2GS manages two independent switching channels with a capacity of 10A per channel and a total maximum load of 16A. Each channel can be controlled separately via the eWeLink app, by voice command, or locally via external switches (toggle or push button). The ESP32-C3FH4X microcontroller from Espressif ensures reliable performance and stable 2.4GHz Wi-Fi connectivity.

Important note: this model requires a neutral wire to operate. Installation must be carried out by a qualified electrician and protected upstream by a circuit breaker or RCBO with a maximum of 16A.

KEY FEATURES

• Guaranteed universal Matter compatibility: The adoption of the Matter protocol ensures seamless integration with all current and future home automation ecosystems. Control your two channels simultaneously via Apple Home on iPhone/iPad, Google Home on Android, Alexa on Echo, or SmartThings on Samsung. Create complex multi-brand routines mixing SONOFF, Philips Hue, Eve, Aqara, and other devices without platform limitation.
• High-capacity independent dual channel: Each of the two outputs switches up to 10A (2400W at 240V), with a cumulative maximum of 16A to ensure installation safety. Ideal for controlling two separate lighting zones in the same room (ceiling light + wall lights), two bedside lamps, or lighting + fan combinations. Each channel remembers its last state after a power outage to automatically restore its configuration.
• Preserved local control via existing switches: Inputs S1 and S2 accept both traditional toggle switches and modern push buttons. The switch type can be easily changed with a triple press on the configuration button without any disassembly. This flexibility allows you to maintain the aesthetics and ergonomics of your existing wall switches while adding smart connectivity.
• Ultra-compact professional installation: With its 45×39.4×16.8mm size, the MINI-2GS fits into absolutely all standard European flush-mounted boxes, even the oldest or shallowest ones. The 16-14AWG automatic terminals directly accommodate solid or stranded copper conductors without requiring additional connectors. Perfect for renovating existing installations without modifying wall wiring.
• Advanced Matter automations and smart scenes: Schedule personalized weekly timings for each channel independently. Create scenes combining your two channels with other Matter devices: "Good night" gradually turns off the ceiling light (channel 1), keeps the nightlight on (channel 2), and locks the connected door. Automations synchronize across all your compatible Matter platforms.
• Native Home Assistant integration: Automatic recognition via Matter integration in Home Assistant without manual configuration. Full exposure of both switch entities with state, consumption, and diagnostic attributes. Compatible with complex YAML automations, community blueprints, and customized Lovelace dashboards. Also works with Node-RED for advanced visual automation flows.
