Sonoff MINI-ZB2GS-L ZigBee 3.0 Two-Channel Mini Switch - No Neutral Required - 2 Circuits Smart Relay Module
Upgrade a traditional wall switch to smart control without rewiring your home. Sonoff MINI-ZB2GS-L is a compact ZigBee two-channel mini switch designed for installations where there is no neutral wire (N) in the wall box - ideal for many older homes. It lets you control two separate circuits (L1 and L2) independently, so you can manage two lighting zones from one location while keeping your existing switches and wall plates.
Once paired with a compatible ZigBee gateway, you can switch lights on/off remotely, create schedules and timers, and build smart scenes for daily routines. It also supports advanced options like disconnected relay mode, where the wall switch can trigger automations without physically cutting power - perfect for smart scene control. OTA firmware updates keep the module current without taking it out of the wall.
Key Features and Specifications
- No neutral wire required - designed for installations with only a live (phase) wire in the wall box
- 2 channels (L1 and L2) for independent control of two circuits or lighting zones
- Load capacity: up to 8A per channel, 12A total (suitable for typical home lighting loads)
- ZigBee 3.0 standard - requires a ZigBee gateway for pairing and remote control
- Compact module size designed for standard 60mm wall boxes (approx. 45 x 39.4mm body footprint)
- Works behind traditional switches and supports multiple switch types, including SPDT (depending on wiring setup)
- Disconnected relay mode to use the wall switch as a smart scene button (automation trigger)
- Power restore settings - choose device state after a power outage
- OTA updates supported for easier maintenance and feature improvements
- App-based control features: remote on/off, timers, schedules, smart scenes, and event history (via compatible platform)
Ideal Examples of Usage
- Living room: control ceiling lights and wall lamps separately using the two channels
- Kitchen: switch main lighting and under-cabinet lighting as independent zones
- Bedroom: manage bedside lamps and main light as two circuits without changing the wall switch
- Hallway + stairs: set one channel for hallway lights and one for stair lights, with schedules for evenings
- Smart scenes: use disconnected relay mode so a wall switch press starts a "Movie Night" or "Good Night" automation instead of cutting power
Why This Product Is Perfect to Buy
MINI-ZB2GS-L is a practical way to modernise older electrical installations because it works without a neutral wire and does not require an extra bypass. You get flexible two-channel control, smart scheduling, and automation features while keeping the look of your existing switch. The ZigBee mesh approach can also improve reliability in multi-device homes, and OTA updates help keep your system up to date without extra work.
Interesting Facts About ZigBee and Two-Channel Switch Modules
ZigBee devices can form a mesh network where powered devices often help relay signals between other devices, improving coverage across rooms. Two-channel mini modules are popular for space-saving upgrades because they can control two circuits from one compact unit, reducing the need for separate relays and making lighting zones easier to manage in one place.
