Product detailed description

🧠 Sonoff Mini DUO - L: Simplicity and intelligence in one!

SONOFF MINI DUO-L (MINI-ZB2GS-L) is a dual-channel Zigbee 3.0 smart switch designed for installations without a neutral wire. It supports two independent channels with a total rated load of up to 12 A, allowing two-way control of two devices for flexible and seamless lighting management across floors, while preserving manual control via traditional wall switches.

Zigbee Protocol

Thanks to the Zigbee 3.0 protocol, it works with various open-source platforms (Home Assistant (ZHA, Zigbee2MQTT), SmartThings, and other Zigbee 3.0 hubs for cross-device automation. You can control it via app, voice control with Alexa / Google Home (via a supported Zigbee hub), or set timers for automatic operation.

Small Size, Double Control

Thanks to its ultra-thin casing, it fits into most European wall boxes (Ø60 mm), making it an ideal solution for retrofitting smart control into older buildings.

No Neutral Wire Required

Thanks to its ability to adapt to single-wire installations in older apartments, it allows direct installation without any circuit modifications. It is a practical solution for hassle-free upgrades of legacy home wiring.

Time and Labor Saving

Smart load control from 3W, easy to set up – no additional anti-flicker module required (its use is not recommended).

Smart Upgrade

Highly flexible and compatible with various types of external switches, ensuring broad usability and adaptability to all your needs.

Upgrades conventional switches with smart features that enable control via app or voice, and easy timer configuration for convenient, automated home control.

Detach Relay
