The Sonoff Mini Duo (Zigbee) has Dual Control for efficiency. The “Duo” capability allows you to control two distinct electrical circuits (2 Live Outputs) from a single unit. Despite this dual functionality, it retains the ultra-compact “Extreme” form factor, making it small.

Retain Physical Control Don’t lose your traditional wall switches. The S1/S2 ports allow you to wire your existing 2-lever rocker switches directly to the unit, giving you the best of both worlds: smart app control and familiar physical switching.
