## Summary description

The Sonoff S-MATE is a wired smart home light controller in white. It operates on battery or AC power with a voltage range of 100-240V. Compact dimensions of 54mm width, 45mm depth, and 24mm height make it easy to install. Ideal for controlling lighting in smart home setups.

## Long description

The Sonoff S-MATE Switch Mate is a compact smart scene switch that converts an existing ordinary wall switch into a controller for smart devices. It can be paired with eWeLink-Remote gateway devices such as the MINI R3 to enable remote local control without requiring a neutral wire in the mounting box. The device is available in white and supports battery-powered operation as well as AC power within 100–240 V, making it suitable for retrofit installations where adding wiring is impractical.
Advantages
S-MATE allows a standard 1/2/3-button wall switch to act as a remote controller for paired gateways, providing local control via eWeLink-Remote signals. Its battery-powered design eliminates the need for a neutral wire in the mounting box, simplifying installation in older homes. The compact dimensions (54 mm × 45 mm × 24 mm) make it easy to fit behind existing switches or in shallow mounting boxes.
Suitable for (tasks / use cases)
 Retrofit smart control for ordinary wall switches
 Integrating existing switches with a MINI R3 or compatible eWeLink-Remote gateway
 Homes without neutral wiring in the switch box
 Local scene control of smart lights and other eWeLink-compatible devices

How to use
Install the S-MATE behind an existing 1/2/3-button wall switch and pair it with a compatible eWeLink-Remote gateway such as the MINI R3. After pairing, the ordinary wall switch will act as a remote controller, sending local control signals to the gateway via eWeLink-Remote. Because S-MATE is battery-powered, no neutral wire is required in the mounting box; follow the manufacturer instructions for battery installation and secure placement behind the switch plate.
Usage recommendations
Place the S-MATE inside the switch mounting box where it will not obstruct mechanical switch operation and ensure reliable signal transmission to the paired MINI R3 or other eWeLink-Remote gateway. Replace batteries according to the device manual and verify compatibility with your gateway before installation.
