if you have programmer for ST MCU, also is ok.
give me your relay controller model, is it KC868-H8? I will send you firmware.
I have a similar problem! I ordered a button switch module for KC868-Hx relay controller. How can I get the firmware for my controller? I have an ST-link usb cable. My model is KC868-H32
