Expert Verdict

The SONOFF MINIR4 is an ultra-compact Wi‑Fi smart switch with an ESP32 MCU and a 10A relay, plus labeled serial pads for flashing custom firmware. Good for tight retrofit installs and Home Assistant or ESPHome integrations, but expects hands‑on soldering and correct mains powering; not suitable for inductive loads above its 10A rating.

Best For

For DIYers and Home Assistant users who need an ESP32‑based, tiny in‑box smart relay; avoid if you can't solder or need to drive inductive motors above 10A.

Pros

+Very small form factor fits behind standard wall switches for seamless retrofits.
+ESP32 SoC provides fast, stable Wi‑Fi and broad firmware compatibility (eWeLink, ESPHome).
+Labeled Rx/Tx/GND pads and exposed boot method let you reflash with esptool/ESPHome.
+Supports multiple switch types and a Detach Relay mode for independent relay control.

Cons

−Flashing requires delicate soldering; Vcc pad coated and small, careful scraping needed.
−May reboot when powered from weak USB supplies—needs mains-level supply during Wi‑Fi startup.
