{"NAME":"Gosund 112v3.4","GPIO":[56,0,57,0,132,134,0,0,131,30,21,0,0],"FLAG":4,"BASE":18}{"NAME":"SP112new","GPIO":[57,0,56,0,132,134,0,0,131,30,21,0,0],"FLAG":4,"BASE":18}This device now comes with a Wi-Fi module incompatible with Tasmota
For more accurate energy consumption measurements this device requires power monitoring calibration.
For your convenience: GPIO0 corresponds to the red LED, GPIO2 to the blue one. The relay at GPIO13 switches the USB ports, GPIO14 switches mains. To tell the difference from the older model, check if GPIO13 actually switches the USB ports.
