Board is working fine with rs485 sensors, but I'm planning to use relays to control electric circuits and I have two major difficulties :
1) by default I want to have circuits off (NC), I changed settings of all relays in nodered to invert switches, but when board starts it triggers all relays for a moment ON and after moment all goes to OFF. It means that all connected electric equipment will start for a less a second - this is very unwanted behaviour, how to avoid that?
2) I'm planning to use digital inputs to control relays with momentary buttons, but input seams to be connected with relays and input has to be shorted with GND all the time, how to change that, so relay will be toggled wen button is pushed for a moment?  I don't want to use bistable buttons, as relay will be connected with nodered and homeassistant in parallel and wall buttons will have different state than circuit

Hardware

Goal
  1. Daisy-chain several KinCony RS485 I/O modules to the Server Mini’s onboard RS485.
  2. Control/monitor them from Home Assistant OS (HA Modbus if possible).
  3. Best-practice for addressing many modules (bulk provisioning) without connecting a laptop each time.




What I’ve found / tried so far
  • The board exposes RS485 via the Pi’s UART (I see pins marked GPIO14 = TX, GPIO15 = RX on documentation/pins).
  • On Home Assistant OS, I cannot just edit /boot/config.txt like on Raspberry Pi OS, so I’m not sure about the correct way to enable the UART for the onboard RS485 under HA OS.
  • I tried using generic HA Modbus config but I’m not 100% sure about the device path (e.g. /dev/ttyAMA0, /dev/ttyS0, or /dev/serial/by-id/...) and serial parameters (baud, parity, stop bits) for KinCony’s RS485 port on this board.




Questions

  1. Wiring
    • Do I need a 120 Ω termination resistor at the last device? Are there built-in bias resistors on the Server Mini’s RS485 transceiver, or should I add my own?
    • Any max bus length / topology recommendations? (I’ll use daisy chain, not star.)

  2. Protocol & parameters
    • Do those RS485 I/O modules speak Modbus RTU out of the box? If yes, what are the default serial parameters (baud, parity, stopbits) and the register map (coils/inputs/holding)?
    • If it’s not Modbus RTU by default, is there a Modbus firmware or config mode I should use?

  3. Addressing multiple modules
    • How do I set unique addresses for each module? DIP switches? Command?
    • For bulk installs, is there a recommended workflow to assign addresses without hooking up each module to a PC? (Auto-addressing, scan/assign tool, etc.)

  4. Home Assistant OS specifics
    • On this KinCony board with HA OS, what is the correct serial device path for the onboard RS485 (e.g., /dev/ttyAMA0)?
    • What is the recommended way to enable UART on HA OS for this board (since /boot/config.txt is read-only under HA OS)? Any KinCony-specific steps or an add-on?
    • A minimal, known-good Home Assistant modbus: YAML example for one RS485 I/O module would be super helpful.

  5. Examples
    • Could you share example register addresses (coils/inputs) for:
      • Reading digital inputs from a KinCony RS485 I/O module
      • Controlling a relay output (if the chosen module has relays)
    • Any sample configs for more than one module on the same bus?
