Unfortunately , the board you’re trying to use is not compatible with ST_Anything. I believe it uses a serial communications protocol between the ESP01 and the board to control all 4 relays
You could use this board instead, which definitely works with ST_Anything, as I have one that I tested it on.
Note: this board does require a 5vdc power supply with a barrel connector. You also need a USB to 3.3v UART board to program it the first time. Afterwards you should be able to program it Over The Air (OTA).
Here is an example of a USB to UART board used to program and debug the Linksprite and other boards.
