Two-channel smart wall switch Sonoff MINI-2GS-E — compact in-wall relay for two circuits, Matter-compatible

The Sonoff MINI-2GS-E is a two-channel smart wall switch designed to fit behind standard wall switches and convert two independent circuits into remotely controllable loads. Its compact in-wall relay form factor enables installation in existing electrical boxes without adding visible hardware, while Matter compatibility allows integration with Matter-capable ecosystems and basic cross-vendor interoperability. The module supports separate control of two outputs so lighting fixtures or small appliances can be switched independently from the same device.

Advantages

The compact design reduces the need for extra wiring space and preserves the original switch appearance. Matter compatibility simplifies setup with supported hubs and voice assistants that implement the Matter standard. Two-channel operation provides independent control of two circuits from one module, and the in-wall installation offers a cleaner, concealed solution compared with inline smart relays. The unit is suitable for retrofitting conventional switches to enable remote on/off and basic automation without replacing faceplates.

Suitable for

• Converting conventional wall switches to smart control for indoor lighting
• Retrofitting dual-circuit lighting (e.g., two bulbs or two circuits in one box)
• Controlling small appliances or fan and light pairs from a single module
• Integration into Matter-enabled smart home ecosystems
• Installing inside standard EU-style wall boxes where space is limited

Key specifications

• Two independent relay channels for separate on/off control
• Compact dimensions suitable for standard electrical wall boxes
• Matter protocol compatibility for local and cloud-enabled ecosystems
• Intended for in-wall installation behind existing switches
• AC mains operation designed for household circuits (supply and load connections required)

How to use

Install the MINI-2GS-E inside the wall box behind the existing mechanical switches, following local electrical codes and turning off power before beginning work. Connect the supply live and neutral to the module as required and wire each of the two output channels to the corresponding switch/load. After wiring and restoring power, pair the module with a Matter-capable controller or app according to the manufacturer's pairing procedure to enable remote control, scene integration, and voice assistant access. Local manual switches continue to function as usual for on/off control.

Usage recommendations

Ensure installation is performed by a qualified electrician or a person familiar with mains wiring. Verify compatibility of connected loads with the relay current and voltage ratings, and allow adequate space in the wall box for the module and wiring. Use Matter-enabled controllers and updated firmware to maximize interoperability and security.
