When connecting the controllers via Modbus RS485, what is the code used for configration.YAML
The controllers are (KC868-SERVER , KC868-16T, KC868-H32BS , KC868-16S and KC868-8T)

if you want E16S and E16T work as RS485 "SLAVE" mode, you can download "KCS" firmware to board. E8T not support "KCS" now, maybe in furture we will update it. your KC868-Server just use modbus command to control every board's relay. the video already demo showed how to control one relay board. other boards just have different RS485 address, all use this way.
