Hello, can someone please show me how to connect this error
A fatal error occurred: MD5 of this file does not match data in flash! 
 I have been trying to upload my code from arduino IDE but it keeps on complaining about that error

Which and Where is the binary file to be flashed for the board KC868-A8S  ? 

Can this be used with RS-485 port to Read DI and SET/REST  relays?

Thanks.

hello!
How to integrate with the Home Assistant application installed on the Kinocny server, RPi4? Does the KC868-A32 support the mqtt protocol, I'm afraid not? I want to connect 2 KC868-A32 and 1 Kincony server with Rassbery so that the Home Assistant app can manage and supervise it all. Can I ask for some instructions or advice?

How can Smart switch panel be used and programmed with the KC868-E16T

Different board will have different channel of digital output, digital input , ADC, DAC, so the protocol is same , just according to the hardware resource to set channel number.
