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 ARDUINO ESP32 4 CHANNEL RELAY MODULE – KC868-A4 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:
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: Domedia NextCloud
Any ideas what’s wrong here ?
Thanks
