SONOFF MINI R4 4-Pack WiFi Smart Switch (2-Way DIY Relay, Detach Relay Mode, ESP32 Chip, Alexa & Google Home Compatible)

Upgrading standard in-wall light switches to smart home automation frequently poses major installation hurdles: bulky relay modules often refuse to fit inside shallow European junction boxes, and flipping a physical wall switch can disrupt automated routines and smart bulb responsiveness. The SONOFF MINI R4 overcomes these pain points with its ultra-compact form factor and next-generation ESP32 microcontroller. Designed to nestle discreetly behind conventional switches or inside compact mounting enclosures, it converts existing lighting into a smart setup without altering your home's aesthetics. Its innovative Detach Relay mode isolates the mechanical switch state from the internal relay, allowing you to use wall toggles naturally without interrupting automated schedules or cutting power to connected smart lamps. It also acts as an eWeLink-Remote gateway, pairing seamlessly with wireless sub-devices for multi-way wireless control without running extra wiring. Home automation enthusiasts and DIY installers applaud its responsive sub-500ms command latency, rock-solid Wi-Fi stability, and native compatibility with Alexa, Google Home, and Home Assistant platforms.
