KCS + modbus + HA - kremilek - 11-12-2023
Hello,
do you have training / description / example focused to modbus ussage in KCS and commnucation implementable to HomeAssistant? I would like to read data over RS485 (ideally more register addressess) via KC868-A8S and transfer them to HomeAssistant.
Regards
Radovan

This is with ESPHome, is it possible also with KCS FW?
RE: KCS + modbus + HA - kremilek - 11-13-2023
Hello,
i did try to configure using ESPHome. Working ok, configuration via KCS is no more needed. Input / output are the same as on KC868-A8, right? I have downloaded IO pin description from ESPHome from file ( Made_for_ESPHome_KC868-A8.zip ) in this thread - https://www.kincony.com/forum/showthread.php?tid=1745
Below attaching configuration for A02 ultrasonic distance sensor + KC868-A8S connected via ethernet, maybe this will be useful also for anybody else who want to measure water level in tank :-)

thanks, exactly you not need to use KCS, only use ESPHome to config is enough.
