Sonoff S31 is a 15A smart plug with built-in energy monitoring (real‑time wattage, voltage, current, kWh) and both Wi‑Fi/Zigbee flavors that integrate with eWeLink and Home Assistant. It’s a solid choice when you need per‑outlet power measurements and automation (power thresholds, CSV export), but expect a fairly chunky enclosure, occasional Zigbee repeater quirks, and some setup nuance for local/MQTT use.
Buy if you need per‑outlet energy monitoring (15A) and Home Assistant/eWeLink integration; avoid if you need a slim plug or a rock‑solid Zigbee repeater.
