Hi All,

I just purchased one board KC868-A8S but is seems i am usung wrong protocol.

When sending any message i receive an just an echo of same command.

i need to flash any firmware?  
where i can find a communication protocol?

Please help, 
Luigi.

How to make communication with an HMI, by Ethernet?

command does not work, it was supposed to give a command that if button 1 was LOW, it would activate output P0, what did i do wrong to make it not work?

Hi,

I tried turning on and off without any problem, esphome is working.
But when i check the board, the output led does not light up when i turn it on.
Below are the yaml i used, is there anything missing or wrong that causes the led not to light up when i switch it on using esphome?
Btw i have not connect or use any DC12/24v input yet.

Hello,

I looking for the tasmota FW and config file for the KC868-AI

any advise?

I just received a KC868-A8S board and am not able to get it to work. I started with the relay sample program. I copied pin_arduino.h to the project and changed SDA and SCL to 4 and 5 respectively as indicated. I also added static_assert statements to make sure that the correct values were picked up. The program compiled and loaded successfully. The pcf.begin() statement returns false indicating an error occurred. I then tried the sample I2CScanner project, mad the same changes and ran it. It indicated that there were no I2C devices detected. I also have a KC868-A4 which works correctly. The code is different but all the wiring is the same so I don't thing I have any cable problems.
