  • Connectivity

    ZigBee

    Special connectivity network for smart devices that offers high stability and energy savings.

  • Usage

    Lighting

    For remote control of lamps and lighting fixtures.

  • Compatible Application

    The compatible app that you download to your mobile phone to control the switch remotely.

  • Maximum Load

    It is the maximum amount of current that the switch can withstand without burning out. It shows you how many or how powerful devices you can connect: for simple lights, 10A is enough, while for power-hungry devices (such as a water heater) more Amperes are required.

    For example, a typical LED bulb (e.g. 10W) draws very little current, about 0.04 Amperes. This means that a standard smart switch of 10A is more than sufficient for its operation.

  • Wiring

    Without Neutral

    For installations where there is only 1 wire in the switch box on the wall (phase).

  • Dimmer

    It allows you to adjust the brightness of the lighting instead of simple on/off operation. Bulbs that support dimmable function are required.
  • Dimensions 45x39.4x16.8mm

  • Smart Ecosystem

    Alexa

    The Amazon automation platform based on the Alexa voice assistant. It offers voice control capabilities and the creation of "Skills" for connecting and automatically coordinating multiple smart devices.

Description

The SONOFF MINI DUO-L (MINI-ZB2GS-L) is a dual Zigbee 3.0 smart switch designed for installations without grounding. Thanks to its ultra-slim design, it fits most European (Ø60 mm) wall sockets, making it an ideal solution for upgrading smart control in older installations. It supports two independent channels with a total load of up to 12 A, while maintaining manual control via traditional wall switches.

Zigbee management provides reliable local operation without cloud requirements and ensures broad compatibility. With support for schedules, automation, and voice control, the switch seamlessly integrates into everyday routines. Note that the minimum load must be at least 3W.

  • No grounding required for installation: does not require a ground wire, ideal for upgrading older electrical installations. Note: The connected load must be at least 3W.
  • Two independent channels: controls two separate circuits from one compact unit, up to 12 A total supported load.
  • Ultra-compact size: fits behind most Ø60 mm EU sockets.
  • Wide switch compatibility: works with momentary or rocker switches via S1/S2 inputs.
  • Reliable Zigbee control: stable operation with local control even when internet connection is unavailable.

    UNACCEPTABLE. Three have burned out on me so far. Under no circumstances does it withstand the watts & A it claims. Luckily we didn't get burned alive, so that's good. But it's wasted money. For some simple operation at lamp wattage, it's fine, otherwise stay away…
