Configuration
{"NAME":"ESP12F_Relay_X16","GPIO":[1,1,1,1,1,7712,1,1,7680,7648,7744,1,1,1],"FLAG":0,"BASE":18}This device uses two 74HC595 serial registers to control the relays, which are not enabled in default builds. Therefore you need to compile your own Tasmota binary, enabling USE_SHIFT595 setting.
