Hi

I'm tyring to use a K868-Uair with ESPHome but I have some problems ! According at Kincony ducomentation it should GPIO32 and 33 to control RGB LEDs of bottom ring and vertical bar ! Unhappy these two GPIOs are doing exactly the same thing: control the ring only and only 3 LEDs of it
Someone has the proper GPIO configuration of that board ?
Noticed also that the Dallas temperature sensor is a chinese copy I think as it's 4/5° offset of other temperature sensors I have in the room

Code used so far in ESPHome for LEDs:

KC868-COLB support use by MQTT or TCP Server or TCP Client work mode. When using MQTT, use Json format send command. When using TCP by HEX format command. KC868-COLB's PC software support "DEBUG" mode for programmer developing.
   
open your KC868-COLB PC software, use mouse left button quick click > 5 times will enable "DEBUG" mode.


   
this page for debug relay


   
this page for read digital input, analog input and DS18B20 temperature sensor data.

   
this page for debug set temperature and analog input threshold and RTC clock

   
This is write RTC clock example.

for example, set RTC clock:
we set 2022-03-08  21:38:00 to KC868-COLB

send command is:
5E 01 32 C0 06 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 16 03 08 15 26 00

0x5E 01 : begin byte, never change it.
0x32 C0: command type
0x06 00: message length  now the message is "16 03 08 15 26 00"  total 6 bytes
0x00 ... ... 00  38 of 0x00 retain bytes, not chang it.
0x16 03 08 15 26 00 is year,month,date, hour,minute,second
0x16=22 use two last number of year, default begin with20 so year=2022
0x03=03
0x08=08
0x15=21
0x26=38
0x00=00

install the ZigBee dongle will support ZigBee 3.0 device by zigbee2mqtt in home assistant.

   

A is +, K is - for IR tube
   

This cable is extend IR for 3 meter.
   

IR receiver: GPIO22
IR sender: GPIO23
433MHz wireless receiver: GPIO13
GPIO-1: GPIO4
GPIO-2: GPIO5
GPIO-3: GPIO18
GPIO-4: GPIO19

GPIO1-4 can use for LED Strip/DS18B20/DHT11/21 Temperature and humidity sensor.

KC868-Server is a super smart controller for smart home automation and industrial automation control. KC868-Server smart controller support MOSFET output and wall switch connect to it directly. Also have analog input and digital input ports. The most important is integrated Raspberry pi CM4 module. Also integrated ESP32 module for you to write your own code. It’s very powerful and flexible.

improvement:

1. Fixed an issue where mqtt would disconnect under certain circumstances
2. Fixed the bug that some times more than 23 relays could not be controlled at the some time
