Sonoff MINIR4 — Wi-Fi Smart Switch | ESP32 | Detach Relay | Works with Alexa & Google Home

Sonoff MINIR4 MINI Extreme Wi-Fi Smart Switch

The Sonoff MINIR4 is the smallest, most capable Wi-Fi smart switch Sonoff has ever built — compact enough to disappear inside virtually any wall box, yet powerful enough to transform any ordinary switch into a fully automated smart home control point. No hub, no rewiring headaches — just install, connect to Wi-Fi, and start automating.

At just 39.5 × 33 × 16.8mm, the Sonoff MINIR4 is small enough to fit inside even the tightest European-standard gang boxes, making it the perfect retrofit solution for Lebanese homes and offices with limited wall cavity space. Powered by the dual-core ESP32 chip, it delivers fast, stable Wi-Fi connectivity on the 2.4GHz band with no additional bridge or hub required — just your existing home network and the free eWeLink app.

What sets the MINIR4 apart is its intelligent Detach Relay Mode — a feature that separates the physical switch state from the relay state. This means pressing your wall switch won't forcibly override the app or automation you've set, giving you true independent control between manual and smart operation. Combined with support for multiple external switch types — momentary, SPDT, latching, door exit switches, and dry contact sensors — the MINIR4 fits into virtually any existing wiring setup without modification.

Voice control works seamlessly with Amazon Alexa and Google Home, and full smart scene automation is available through the eWeLink app, including timers, countdowns, loop schedules, and conditional triggers linked to other smart devices. The MINIR4 also acts as a local gateway for eWeLink-Remote sub-devices like the R5 and S-MATE, enabling wireless multi-switch control of a single light without any internet dependency.

For Lebanese homeowners, electricians, and smart home enthusiasts looking to automate lighting and appliances room by room — the Sonoff MINIR4 is the most practical, affordable, and professional-grade solution available, certified by TÜV, CE, and FCC for safe residential installation.
