Enjoy seamless control over your smart devices with the SONOFF Smart Switch. Easily install this switch into a standard wall switch box and pair it with compatible devices like the MINI R3 (sold separately) for remote operation, even without internet access. It supports 1/2/3-button switches and is powered by a CR2032 battery.

Convenient Device Control
Connect the MINI R3 switch with the S-MATE device and manage your connected devices locally via the eWeLink-Remote signal. It offers dual control methods and works with 1/2/3-button switches, so you can toggle devices or activate scenes in the eWeLink app. The S-MATE boasts a range of up to 50 meters.

Easy Installation and Configuration
Installing the S-MATE is straightforward; simply place it in the switch box. Powered by CR2032 batteries, it doesn't require a neutral wire (N), making it perfect for older installations. Note: A compatible switch like the MINI R3 is needed for optimal operation and is available separately.
