SONOFF S31/S31 Lite 15A US Wi-Fi Smart Plug Wireless Switch Overload Protection Remote Control via eWeLink Support Google Alexa
Networking
“The Sonoff S31 / S31 Lite is a 15A smart plug with energy monitoring and either Wi‑Fi (S31) or Zigbee (S31 Lite) connectivity; it supports cloud control via eWeLink but also can be reflashed to local firmware (ESP8266/ESP8285) for privacy and Home Assistant integration. Good for users who need 15A load capacity plus wattage/voltage/current metering, but expect initial flashing hurdles for local firmware and some Zigbee repeater limitations.”
