ok, i think there are 2 solution for you:
1. i have said, use a extend relay , when voltage <12v , it will OFF, you can connect to A8 board's S1,S2,S3,S4, i think you have not use these ports, these port also can use for digital input signal.
2. add INA226, it's i2c power monitor chip to A8 board's IIC extender. then you can config INA226 by ESPHome, here is details:

if you only want RF remote control relay ON/OFF and monitor power make AUTOMATION, esphome also can do that. you can config esphome do anything, not need to use KCS firmware.
