Control an RS485 device with KC868_A6 from Home Assistant

[marc.domotique]

Hello,
I'm using Home Assistant to control my home.

I bought a KC868_A6 (currenly with Software Version v2.2.14) in order to :

1. use built-in digital Inputs & outputs
   
2. get values from built-in analog inputs
   
3. control a  PowerFlex 4M AC drive (send commands / receive status) via RS485 port
   

I'm using protocol MQTT and for 1 & 2, no problem, all works as expected.
But for the 3, I don't know how to proceed. Does someone have an idea please ?
Thank you in advance for your help.

you can config by esphome according to your AC driver's protocol.

Hi,
Thanks for your prompt answer. So meaning that there is no way to use MQTT with HA to control a RS485 device?

yes, KCS v3 firmware ONLY use by KinCony TS RS485 temperature sensor for MQTT.
