Serial command ?? - vincen - 01-15-2023

Hi

First time trying to use serial control with HA (have done it for years with antic automation system like AMX, Crestron ones) but I struggle to get it working with HA and ESPHome.
I'm using the Kincony K868-A4 box https://www.kincony.com/arduino-esp32-4-channel-relay-module.html to get a serial port.
I have tried wiring serial port between kincony and device controlled straight or crossed but not better ! (product was controlled previously without problems by a Crestron system).
Here is code used in ESPHome:
Code:
substitutions:
  friendly_name: esp-tr-02

esphome:
  name: $friendly_name
  platform: ESP32
  board: esp32dev

logger:

web_server:

ota:

wifi:
  networks:
  - ssid: !secret wifi_ssid
    password: !secret wifi_passwd
  manual_ip:
    static_ip: 172.16.2.81
    gateway: 172.16.1.1
    subnet: 255.255.252.0
  ap:
    ssid: $friendly_name

captive_portal:

api:
  reboot_timeout: 10min
#  services:
#    - service: volume
#      variables:
#        volume: Int
#      then:
#        - uart.write: !lambda
#            return {0x00, 0x20, 0x42};

sensor:
  - platform: uptime
    name: $friendly_name Uptime
    filters:
      - lambda: return x / 60.0 /60.0;
    unit_of_measurement: hours
  - platform: wifi_signal
    name: $friendly_name WiFi Signal
    update_interval: 60s

button:
  - platform: template
    name: CD Input
    on_press:
      - uart.write: "CD\r"
  - platform: template
    name: DVD Input
    on_press:
      - uart.write: "DV\r"

uart:
  tx_pin: GPIO17
  rx_pin: GPIO16
  baud_rate: 9600
  debug:
Protocol of the device I try to control: https://cloud.domedia.net/index.php/s/g6ANGP9CLbaG7iK

Any ideas what's wrong here ?

Thanks

Vincèn

i think firstly, you can send RS232 command by PC to test your command whether is correct.
if your command is correct, then try to config by ESPHome to send command.

I know the syntax of commands and I'm sure they work ! My only problem is to get them working with the Kincony through it's RS-232 port !
Can you confirm my ESPHome code is correct ?

1. suggest you use KC868-A4's digital input make for 4 buttons for test.

binary_sensor:
- platform: gpio
name: "input1"
pin:
number: 36
inverted: true

- platform: gpio
name: "input2"
pin:
number: 39
inverted: true

- platform: gpio
name: "input3"
pin:
number: 27
inverted: true

- platform: gpio
name: "input4"
pin:
number: 14
inverted: true

2. you can add these for a test:

on_...:
- uart.write: 'CD'

3. if can't work, you can try to exchange your RXD,TXD pin, such as :
uart:
tx_pin: GPIO16
rx_pin: GPIO17
baud_rate: 9600
