SONOFF MINIR4 Extreme Wi-Fi Smart Switch

The Sonoff MINI R4 is a compact Wi-Fi smart switch that upgrades your regular wall switch—no neutral wire needed. It fits behind most switches or inside small electrical boxes, making it perfect for older homes or retrofits.

It supports both 1-way and 2-way switch setups, so you can use it in hallways, staircases, or anywhere that needs flexible control. You don’t need to change any existing wiring.

The switch connects to your 2.4 GHz Wi-Fi and works with the eWeLink app, giving you remote control through your phone. It also supports Amazon Alexa, Google Home, and SmartThings for voice control.

The built-in Extreme Mode makes switching faster and more stable. It also improves safety with better power isolation. You can even mount it on a DIN rail for organized panel installations.

An external switch input lets you keep your regular wall switch while still controlling it from the app. Set timers, automate scenes, and check device status from anywhere.

Use the MINI R4 for lights, fans, or small appliances. It’s a reliable choice for building or expanding your smart home.
