improvement:
add HTTP multi control relay command ( you can use one http command turn ON/OFF/toggle any relay) :
http command format:
http: //ip/sw_ctl.cgi?RealyMulSet=A8A7A6A5A4A3A2A1,B8B7B6B5B4B3B2B1,C8C7C6C5C4C3C2C1&postpwd=postpassword

A8A7A6A5A4A3A2A1 use for "TURN ON" 32 channel relay, every channel bit "1" means enable, bit "0" means disable
B8B7B6B5B4B3B2B1 use for "TURN OFF" 32 channel relay, every channel bit "1" means enable, bit "0" means disable
C8C7C6C5C4C3C2C1 use for "TOGGLE" 32 channel relay, every channel bit "1" means enable, bit "0" means disable
every Ax or Bx or Cx use by HEX format data.
   

For example:
if you want to
                 TURN ON  RELAY 32 31 30 29  (F0000000)
                 TURN OFF  RELAY 04 03 02 01  (0000000F)
                 TOGGLE  RELAY 24 23 22 21  (00F00000)
if your relay controller IP address is 192.168.1.200
if your post password is 12345

At last the HTTP command is :  http://192.168.1.200/sw_ctl.cgi?RealyMulSet=F0000000,0000000F,00F00000&postpwd=12345

   
After send this command: Relay32,31,30,29 will be ON,  Relay4,3,2,1 will be OFF,  Relay24,23,22,21 will be TOGGLE.

Hello. Is it possible to connect and use the Dahua ASR1100A ASR1100A (13.56MHz) RFID reader with COLB module? The RFIS reader has an RS485 connection. Thank you.

Hi

I'm using a K868-AG without problems to control a TV using the internal IR emitter LEDs. I want to use the GPIO avalaible on the board to wire additional IR emitters to control few other devices.
I have been careful of IR LED polarity. I have wired it between GPIO (positive side) and GND (negative side). I have also tried to add 200ohm resistor but same, it doesn't control device ! I'm sure of my ESP code as it works fine if I change code to use GPIO wired at internal LEDs ! I have tried GPIO14 with resistor and GPIO21 without but same result, not working

Any ideas what's wrong ?

Thanks,

Vincèn

Hi
I have KC868-H32 (2020)  +button switch module for KC868-Hx .All worked perfect until i try  use MQTT for HA  ?
I update firmvare to 4.43   by  USB-RS232. and now switch module  doesnt  work- all lights   
What can i do now? what the last firmware  to H32?  .V4.43 works only with H3xB ?

Where i can find last firmware for H32 
thanks for help

1. create automation - a16-input1-trigger-a16-output1 (control KC868-A16's output)

1. chose LED strip model
2. connect with wire: VCC,DATA,GND
3. config in ESPHome:


light:
  - platform: fastled_clockless
    chipset: WS2812B
    pin: GPIO33    # Pin Define connected with LED strip
    num_leds: 30  #LEDs number
    rgb_order: GRB

1. Change KC868-Server USB boot jumper
2. Connect with USB cable with computer and KC868-Server
3. Power on of KC868-Server
4. Run rpiboot
5. Download and install Raspberry Pi Imager 
6. Manually install an operating system image
7. Connect KC868-Server HDMI to monitor
8. Connect keyboard and mouse to KC868-Server

1. extend output and input ports by hardware device

a. KC868-A series board  (integrate to home assistant by ESPHome)
b. KC868-HxB series board (integrate to home assistant by MQTT)

2. config ESPHome for KC868-A16
