Assistance with RS485 Communication via KC868-A16 & Wemos D1 - Bastn - 03-28-2025
Hi,
I currently have the following setup:
- Wemos D1 (ESP8266) connected to the Wi-Fi network.
- KC868-A16 connected to the Wi-Fi network, running KCS firmware V2.
- RS485 I/O module (25IOB16) connected to the KC868-A16 via RS485 (A/B).
- or IFTTT through the KC868-A16.
- orA Wemos D1 (ESP8266) running Arduino code, connected to the same Wi-Fi network as the KC868-A16.
- I am unable to send or receive RS485 commands via IFTTT on the KC868-A16. (not supported by software?)
- I am unable to send or receive RS485 commands from a small web UI on the Wemos D1 to the RS485 I/O module (25IOB16).
I am looking to replace my current PLC, which simply toggles outputs based on input signals in my house.
Could you provide guidance on how to achieve this?
Thanks!

KCS v2 support send customize command by RS485.
KCS v3 support receive and send customize command by RS485.
KCS v3 use by KC868-A16v3 board.

I have KC868-a16 board (not a16V3)
Therefore I only can send commands using customize command by RS485, correct?
If I want to read / write, I will need to make a new firmware in Arduino for KC868-a16, correct?
