Great product! It has 4 independently buttons for all AC sockets. And one master, controlling all. No independent button for USB, but all work's perfectly using Homeassistant. You need to desolder wifi module before tasmotizing it. I don't know what the analoge input value represent.
Very nice and robust, and easy to integrate in Smart Life APP. It fully matches with the description. Even when it initially offered a delivery time of 2-3 weeks, it finally arrived to Spain in only 5 days.
