Expert Verdict

The Sonoff MINIR4 features a compact form factor for tight wall boxes and an ESP32 chip for reliable, dual-core performance. It is a highly capable, DIY-friendly smart switch that supports advanced configurations like 'Detach Relay' mode, though it requires technical proficiency for custom firmware installation.

Best For

Ideal for DIY enthusiasts comfortable with soldering and custom firmware; avoid if you require a simple, 'plug-and-play' out-of-the-box experience.
