Hi Kincony,
I was buy K868-A16 board. rev 1.5
I need an Arduino source to communicate with the Ethernet port.
Tasmato or Home assistant is not helpful.
Is there an example source for socket communication with the LAN port? (i don't use wifi..because of the reliability..)
Please guide me.

thank you,

Hi
Can I use AT32F415RBT7 MCU Chip with my KC868-H8 board if I want to have MQTT support with new firmware in my board?

Hello admin,

thanks a lot for these really nice PCB, which allow lot of powerful projects!

I've checked the circuits of KC868-A4 (and other KC868-versions) and you are right, the direct GPIO-communication is easier to handle for Arduino-newbies than bus-connected parts.
Nevertheless I found out some optimization for KC868-A4-hardware. Maybe you can use it for an future hw-update.

• cancel RS232 (saves lot of space + USB-C is sufficient for controlling the PCB directly)
  
• change IRD/IRS & 433MT/433MR to 1x I2C-bus (2x ordinary 4-Pin-connectors, i.e. for display & other I2C-parts)
  
• add a connector for an accurate working I2C-DS3231 RTC-modul
  
• make the 2x 0-10V-DAC jumperable also to 2x 0-5V (to control 0-5V-devices)
  
• a relay OR mosfet option would be great (or to get only 1 PCB => 2x relay + 2x mosfet)
  
• ESP32 on a socket => stackable ESP32 (allows different ESP32-versions (i.e. with external antenna) and change of controller, if there is a problem). I know it's more expensive, but fast changing a small ESP32 is a superior feature. I.e. a company can send only the small ESP32-modul to consumer, if somthing went wrong.
  

Hi KinCony IoT,

Is it possible to reach the WebUI over Wifi in STA mode to manage the relays?
I can reach the webUI over LAN port.
Both Ethernet and Wifi are set to TCP-Server.
I was able to configure Wifi in STA mode and connect to my Wifi router. Then I disconnect the wired LAN port, but when I try to connect to the relay over the Wifi IP it doesn't give back the Relay Web UI, but the Wifi ESP32 config UI.
I would like to use HTTP commands over Wifi. Is it possible?

How can I reference the GPIO and analog pins in ESPHome? Can you provide some example? Thanks.

Boa noite.
Eu tenho uma placa WIFI KC868 A6 conectado a um roteador. Mas quando a energia acaba, quando a energia volta, a internet volta mas a placa KC868 A6 trava. Para voltar ao trabalho, tenho que desligar a energia e ligar novamente.
Que solução posso usar?

hello, admin
    What are  products from Kinkony  to conect 10 circuits of LED STIP LIGHT ?
    How to connect them to be dimmable from wall switch and at the same time to be itegrated in app Home Assistant (dimmable and change multy color)?
 
Thank you

Made ESP32 arduino library for KC868-H32B Pro Controller, easy to write arduino code for simple logical, such as sensor trigger relay or timer locally.



here is details: https://www.kincony.com/how-to-use-ardui...b-pro.html

We have made arduino library for KC868-H32B Pro smart controller. it is open source and free for DIYer use.

1. Install ESP32 USB driver to your computer.

download from: https://www.kincony.com/download/CH341SER.zip
after installed USB driver, connect USB cable to your KC868-H32B Pro USB port. 
   

Then you will find COM port in windows OS "device manager"
   

2. Enable "ESP32 Development Mode" by KC868-H32B Pro Ethernet setting.
   

3. Install library in arduino IDE.

   
   
   

here have many demo simple code for how to use KC868-H32B Pro smart controller's relay output and input sensor port.

   
This is sample code how to turn ON/OFF one relay.
