Greetings community,

I trust this message finds you well.

I'm currently engrossed in a project that requires the use of a KC868-ATC as a Modbus master using RS485 RTU to communicate with Modbus slave devices. Despite my efforts to create a simple program using the Modbus Master library for ESP32, I've encountered challenges and believe I'm missing some crucial details.

Could anyone kindly share a basic program or offer guidance on reading holding register data from a Modbus slave device using KC868-ATC as the Modbus master with ESP32?

Your insights and assistance would be immensely valuable. Thank you in advance!

Best regards,

What is the best way to integrate this board to Home Assistant if I would like to use it with RF remote and RS485 io module? I would like to keep the original FW. Is there any example how to do that?
Thanks!

Dear friends.
I purchase a KC868-M16 v1. First i plug usb and 12v power suply, after open url "https://web.esphome.io/" in a browser and connect to de device on port com3, connect fine and push on "Prepare for first use", after a minute finish correctly and ask for "connect to wi-fi" as the video in the kincony channel, but dont list any network in the list, and dont fine it if configure it manual. In the log show this error:  No network found!

Hi,
Can you advise me how to configure sim800l for use with esphome firmware?
Currently yaml is like this:

Good afternoon. Please tell me what is the best way to connect a heated floor, but to regulate not only the temperature that we connect to the KC868-COLBS, but also using a thermostat? I couldn't find a connection diagram on the forum. I understand that we connect the heated floor itself to the reley controller, and the temperature sensors to the KC868-COLBS , but how can we add a thermostat to this circuit? And which one will work best with the kinocny product??


Maybe there is a diagram? I didn't find any information on the forum

Hello, I am a beginner and I have purchased two KC868-A16S modules. I have now realized that they are not compatible with Tuya. Am I correct? I want to control my house remotely via the internet. I understand that with Home Assistant, the Kincony module needs to be connected to a server (a computer or Raspberry Pi) for me to be able to control it remotely. However, with modules that have Tuya, like the KC868-H32B Pro, this is not the case. I would not be obligated to go through a server. Is this true? I therefore want to buy another module, the KC868-H32B Pro, to control it remotely with Tuya. But is it possible to control the KC868-A16S with Tuya if I connect the two modules together with RS485?

1. connect MCP23017 i2c module with KinCony Server-Mini's i2c extend terminal. so that you can extend 16 GPIOs for switch or binary sensor in home assistant.
   
   

2. enable i2c for home assistant.

Add files to enable I2C
In the root of the hassos-boot partition, add a new folder called CONFIG.
In the CONFIG folder, add another new folder called modules.
Inside the modules folder add a text file called rpi-i2c.conf with the following content:
i2c-dev

In the root of the hassos-boot partition, edit the file called config.txt add two lines to it:
dtparam=i2c_vc=on
dtparam=i2c_arm=on

Hi,
is there any possibility to connect the MAX6675 sensor to the KC868-A8? Thank you

Hi Kincony, nice to meet you. i am james from S. Korea.
I have bought a smart controller (A8Sv2) and i am wondering how to connect the HMI(LCD touch ) for this. since it needs serial i/f . can you advise.
