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: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
