I have a problem. I have KC868-H32B Pro, KC868-AK ESP32 Programmable Keyboard, KC868-HA V2. How to connect them together? In Home Assistant, KC868-H32B Pro works with MQTT normally, but I can't connect KC868-HA V2 additionally.
KC868-AK connect to H32B Pro by RS232 cable directly, KC868-AK not need to use home assistant.
HAv2 can connect to your H32B Pro by RS485 cable directly, HAv2 not need to use home assistant.
Ok, it works.
How to make KC868-HA v2 visible in HA?
"Now I have a problem with the KC868-AK ESP32 Programmable Keyboard. When I press the button, it works like a momentary button (the relay turns on for a moment). Can you check the video?
When the Wifi Setting mode is enabled, there is such behavior in ESP32 development mode. When I turn it off, it works normally.

I have one more question.
how to program KC868-H32B Pro to be visible in HA as ESP32?
in H32B Pro ethernet config webpage, there is an option for RS485 type, just chose "special" . NOT chose "RTU".
