Hi, I Have just purchased a KC868 A6 unit and would like to see a user guide on how to connect to this device and upload a program to it from Arduino IDE.

I've tried searching but have not yet found a user guide for the A6.

Thank You

Here is "KCS" firmware for KinCony KC868-A series (ESP32) board.
How to download and use, online guide: https://www.kincony.com/esp32-kcsv2-firmware.html

v2.2.4 improment:
1. replaced new DHT sensor's driver.
2. fixed MQTT protocol format bug.

RS485 Temperature and Humidity Sensor Modbus RTU Use By SHT30
https://shop.kincony.com/products/rs485-...e-by-sht30

Please tell me the parameters of the Sensor to connect it to the controller via the MODBUS bus

1. Device address: What is the default address, how can it be changed?
2. Data transfer rate (Baud Rate)
3. Number of stop bits
4. Number of data bits
5. Parity
6. Transfer type: RTU or ASCII
7. Bus type: I use 4 wires: RS-485
8. Timeouts and delays: which are preferable for it?

Hi!

anybody had implement Modbus ?
I'm having hard time to get mine working.
I'm using esp32ModbusRTU library.

here is my code;

esp32ModbusRTU modbus(&Serial1, -1); 


void modbusTask(void *pvParameters) {
  Serial1.begin(4800, SERIAL_8N1, RX, TX); 
  printf("Serial1 initialized for Modbus\n");
  vTaskDelay(pdMS_TO_TICKS(1000)); 

    // callbacks  Modbus
    modbus.onData([](uint8_t serverAddress, esp32Modbus::FunctionCode fc, uint8_t* data, size_t length) {
        printf("Modbus Response Received - Server ID: 0x%02x, Function Code: 0x%02x, Length: %u\n", serverAddress, fc, length);
        for (size_t i = 0; i < length; ++i) {
            printf("%02x ", data[i]);
        }
        printf("\n");
    });

    modbus.onError([](esp32Modbus::Error error) {
        printf("Modbus Error: 0x%02x\n", static_cast<uint8_t>(error));
    });

   
    modbus.begin();
  vTaskDelay(pdMS_TO_TICKS(1000)); 

   
    while (true) {
        modbus.readHoldingRegisters(0x01, 0x0000, 4); 
        //vTaskDelay(pdMS_TO_TICKS(1000)); 
    }
}

extern "C" void app_main(void)
{
  vTaskDelay(6000 / portTICK_PERIOD_MS);
  printf("Hello world!\n");
 
    xTaskCreate(modbusTask, "modbusTask", 8192, NULL, 5, NULL);

    while (true) {
        std::cout << "In the while\n" << std::endl;
        //vTaskDelay(pdMS_TO_TICKS(1000));
    }

}

#include <esp32ModbusRTU.h>

Hello,
Is any reason why documentation explains that this board can be powered only with with 12V?.
I checked schematic view(LDO) and XL1509-5 can support 24V(input). Any other modules uses 5V or 3.3V.
Can I safely use 24V DC Power Supply instead of 12V? (I assume, that input logic will change from 12V to 24V). Is it safe or maybe I'm missing something?.
The input/output 24V logic is very popular in Europe .

Howdy!

Thanks for the A6 Board, im using the second one already and i enjoy it.
I encountered a problem, connected PZEM-004T to Serial on A6 (GPIO12, 13)

When i power the board, it doesnt boot. I plug out the PZEM-004T from A6, it boots. I plug pzem back in. It works normaly, and i receive all the needed data.
What is the problem i have on boot?

How to use 0-20mA signal insted off 4-20mA

Hello,

I am using a H32B Pro and Home Assistant to control an irrigation system and would like to add another 32 channels? How should I do this? Should I get another H32B Pro or is there an extension module I could use?

Thank you,

David

Hello!!
Could I ask for instructions on how to make roller blinds for ESPhome ? I need some code to run it.
I can't find it on the Internet and what I found doesn't work. I have KC868-A8-V1.6
