Description
The SONOFF S-MATE Extreme is a compact smart switch adapter that retrofits traditional wall switches for wireless control without requiring a neutral wire.
It supports 1–3 button switches and integrates with eWeLink-Remote-enabled devices for local automation.

- Local Wireless Control: Pairs with eWeLink-Remote hubs (e.g. MINIR4, NSPanel Pro, DUALR3) for up to 50m range
- Smart Scene Activation: Triggers automation scenes via eWeLink app or compatible hubs
- Compact Design: Fits behind standard EU/86 or US 120 switch boxes
- Voice Assistant Integration: Works with Alexa and Google Assistant when paired with compatible SONOFF devices
