Hi,

I want to install DS18B20 sensor and use it instead of analog temperature sensor which is not accurate.
Will be using one of the gpio on the white serial port. 

As kcs firmware does not support A32 with DS18B20 sensor, how to make it work.
I can write arudino code to get the temperature if needed, but how can it be use together with kcs firmware?
Need some help. Thank you.

here is KinCony firmware for ALR LoRa board - ALR. it support control relay , monitor DS18B20 temperature and 4 channel analog input, 1 channel digital input state in home assistant by MQTT. You not need config any code for home assistant yaml. Because we have design firmware enabled MQTT auto discovery for home assistant.
   

here are two ALR board.  one work as RECEIVER(gateway), another work as TRANSMIT(read sensor state, control relay), just set DIP switch on PCB, let two board same DIP state, so that they will communication with each other, easy!

   

RECEIVER(gateway) board's LCD displayer will show MQTT broker connection state, LoRa signal value and how many LoRa package have received.
TRANSMIT board's LCD displayer will show DS18B20 temperature value,  LoRa signal value and how many LoRa package have sent.

   

here is two firmware BIN file for different board:

for TRANSMIT board: 
  ALR-TRANSMIT_20240904.ino.merged.zip (Size: 606.17 KB / Downloads: 432)

download firmware by ESP32 DOWNLOAD TOOL:
   
chose ESP32-S3 and USB mode.

   
chose RECEIVER board's firmware and set address to 0x0

   
chose TRANSMIT board's firmware and set address to 0x0

set router's wifi ssid, password, mqtt broker ip, mqtt port, mqtt username, mqtt password for RECEIVER board via USB-C cable.

config json command:
{
  "wifi_name":"KinCony",
  "wifi_psw":"a12345678",
  "mqtt_ip":"192.168.3.124",
  "mqtt_port":"1883",
  "mqtt_user":"mqtt",
  "mqtt_psw":"123"
}

   
serial port debug tool download:

  UartAssist.zip (Size: 468.4 KB / Downloads: 472)

after config complete and reboot. you can see KinCony ALR board is showed on home assistant DEVICE list:
   

you can add these entities to home assistant dashboard.
   

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>
#include "driver/uart.h"

// Declaration Modbus
esp32ModbusRTU modbus(&Serial1, 10); // 10 is arbitary GPIO because don't use RTS pin

printf("Invalid data length\n");
return;
}

for (size_t i = 0; i < length; i += 2) {

if(i < 5)
value = value / 10;
printf("Register %zu: %u \n", i / 2, value);
}

printf("\n");
});

modbus.onError([](esp32Modbus::Error error) {

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?
