how to set KC868-H32B Pro relay inching mode with push buttons

[admin]

   
   
   
   

for example: 
H32B Pro relay1 ON RS485 modbus command is: 01050000FF008C3A
H32B Pro relay1 OFF RS485 modbus command is: 010500000000CDCA

so you can create all custom RS485 protocol command for any buttons.

If you are not familiar with modbus, we suggest you download v1.0.7 firmware to your KC868-AK, because every modbus command, last two bytes is CRC code, it's not fixed. i suggest you download this firmware:

  kc868-ak-v1.0.7.zip (Size: 453.15 KB / Downloads: 46)
you only need download firmware to ESP32, then use your computer connect to the board by AP mode, easy to config every button for every actions.

Okay, I'll do that. Given that this latest version has some upgrades, is there anything that helps me calculate the last 2 bytes of the message?
