The SONOFF MINI-2GS (MINI DUO) is an ultra-compact 2-gang smart switch module with Matter over Wi-Fi support. It fits into standard electrical wall boxes and adds smart functionality to your existing wall switches, including remote on/off control, scheduling, group control, and scenes. It handles up to 16 A total load (up to 10 A per gang for resistive loads), enabling the automation of two separate circuits from a single, hidden module.
Thanks to Matter support, the MINI-2GS integrates seamlessly into multiple smart home ecosystems with unified control and fast pairing. Physical switch control is retained, while remote control expands through app, voice, or automation.
Note: The SONOFF MINI-2GS Matter edition does not support the eWeLink-Remote protocol, so it cannot be used with Sonoff wireless Bluetooth switches or modules. As expected from SONOFF, the product’s quality is backed not only by CE certification but also by testing from TÜV Rheinland.
Compatible with Home Assistant, SmartThings, IFTTT, and Apple Home.
