LeFun SK2 Smart Power Strip (Model ZLD 44USA W) - FengtianGu/Sonoff-Tasmota GitHub Wiki

The LeFun SK2 has 4 mains power and 4 USB ports. Each mains power is independently controlled and the USB group is controllable via a solid state relay. The ESP8266 module inside is likely a TYWE3S by Tuya but I didn't open the case and use the tuya-convert tool to flash.
