The Sonoff S‑MATE2 Extreme Smart Switch Adapter upgrades your regular wall switch into a full-featured smart switch—without needing a neutral wire or any rewiring. It’s perfect for anyone who wants smart control but still wants to use the existing manual switch.
This smart adapter works with the Sonoff Mini Extreme (MINIR4) and connects via Zigbee or the eWeLink Remote Gateway. After pairing, you can use your phone, voice assistants, or automation to control lights and appliances—even without Wi‑Fi near the switch.
Setup is fast and simple. Just mount the S‑MATE2 behind your wall switch and pair it with your hub. Your wall switch works normally, while the smart control runs in the background. It supports up to three-gang switches, making it ideal for areas with more than one circuit—like hallways or large rooms.
Its small size fits neatly into most 86‑type switch boxes. Powered by a CR2032 battery, it runs for months with minimal maintenance. You don’t need to touch any high-voltage wiring, making it safe for DIY installs or rental homes.
The S‑MATE2 is especially useful in older homes where rewiring is not an option. You can upgrade your control system without breaking walls or hiring an electrician.
Use it to set routines, connect to motion sensors, or control multiple switches remotely. It gives you smart control and keeps your manual switch for backup.
Whether you’re automating lights, fans, or other devices, the S‑MATE2 offers flexibility and convenience in one compact device. It’s a reliable upgrade for anyone looking to modernize their home safely and easily.
