I have a usecase for the kc868-a6 that requires the bluetooth to work with esphome. As soon as I enable anything bluetooth related I get fatal errors and the wifi never connects to the network.
This is the code I am trying to use that appears to corrupts the esp32.

substitutions:
name: test
mac_address: C8:47:8C:E1:E2:E2

esp32_ble_tracker:

ble_client:
- mac_address: ${mac_address}
id: client0

switch:
- platform: ble_client
ble_client_id: client0
name: "enable bluetooth connection"

Any thoughts on why the esp32  does not like the bluetooth settings? After removing the bluetooth settings and reflashing I am able to connect to the controller again.
Thanks in advance.

I've defined the digital inputs and switches as in the example and also added a DS18B20 temp sensor to the I2C. But as soon as I add in yaml the Dallas configuration, the update_interval toggles the switches on and off at the interval set in the update_interval.
I saw that the I2C port is the same as the Dallas sensor but I don't know how I can connect them in a different way.

Good afternoon.
In my project, a water level sensor and a temperature sensor are connected to the KC868 A4 controller.
Please tell me which program is better to monitor the readings from the sensor. I tried to connect to Homekit, there were no problems with the temperature sensor, but I didn’t understand how to make the status bar for filling the tank with water.

Maybe tell me how best to implement control from the phone for these sensors through the 4
A4 controller?

And DS18B20

How to use two PCF8574s for DI and DO both?

Next program works correctly when I use only one PCF8574 (adress: 0x22; I2C pins: 4,15) that controls DI inputs on the board:
1.png
   

But it doesn't work when I uncomment code in red frames, trying to add another PCF8574 (adress: 0x24; I2C pins: 4,15) that controls DO outputs on the board.

Correct code for using digital input PCF8574 without errors   "1.png"

I bought this AM2120 Temperature and Humidity Sensor and I am not able to get it to read input sensor on my ESPHOME.  I have bought AM2301 and it works fine with the same ESPHOME code as below:

  - platform: dht
    pin: 33    
    model: AM2302   ## New Sensor AM2120  NOT WORKING - NA reading
    temperature:
      name: "S4-Temp"
      accuracy_decimals: 1
    humidity:
      name: "S4-Humidity"
      accuracy_decimals: 1
    update_interval: 30s

Do I use the wrong code for my board?   

Thanks..

Hello,

I am having difficulty for coding my script, I would like to make a GSM relay which activates the GPIO 15 relay upon the module receipt a call ! but I cannot do it can you help me?

I think my problem is from the command of call detection.

Thanks

Hi, the only GND i see on the A2 is the one also used for POWER IN


I want to connect a PIR , i can take the `3v3` from the board but i am not sure which GND to use . Should i use the same as the `INPUT power` ?

I was following this video 

how to control VFD (Variable Frequency Drive) inverter by KC868-COLB - YouTube

And wrote this code to control my H100 Inverter ( How to: H100 VFD & 1.5KW Air-Cooled Spindle Setup - Zhong Hua Jiang - How To - Carbide 3D Community Site)

import serial

def calculate_crc(data):
    reg_crc = 0xFFFF
    for byte in data:
        reg_crc ^= byte
        for _ in range(8):
            if reg_crc & 0x0001:
                reg_crc = (reg_crc >> 1) ^ 0xA001
            else:
                reg_crc >>= 1
    return reg_crc

# RS485 port settings
rs485_port = 'COM12'
rs485_baud_rate = 115200
rs485_parity = serial.PARITY_NONE
rs485_stop_bits = serial.STOPBITS_ONE
rs485_data_bits = serial.EIGHTBITS

try:
    # Open the RS485 serial port
    ser = serial.Serial(
        port=rs485_port,
        baudrate=rs485_baud_rate,
        parity=rs485_parity,
        stopbits=rs485_stop_bits,
        bytesize=rs485_data_bits,
        timeout=1
    )

    # Send a command via RS485 in RTU mode
    command = [0x64, 0x01, 0x02, 0x20, 0x00, 0x00, 0x01, 0x43, 0xCA]  # Modify the command in hexadecimal format
    crc = calculate_crc(command)
    command.append(crc & 0xFF)  # Low byte
    command.append((crc >> 8) & 0xFF)  # High byte
    ser.write(bytes(command))

    # Read the RS485 response
    response_rs485 = ser.readline()
    hex_response_rs485 = ' '.join(hex(byte) for byte in response_rs485)
    print("RS485 Response:", hex_response_rs485)

    # Close the RS485 serial port
    ser.close()

except serial.SerialException as e:
    print("Error opening or accessing the serial port:", str(e))

This is the code I wrote. The checksum passes, and everything else is fine. But when I run the code, it doesn't reflect any changes on the Inverter/ Motor. Please help.

The connections on the RS485 can be found in the images attached below.

Please help! Thanks in advance.

Dobrý den,
chtěl bych získat zkušební bezplatný vzorek ovladače KC868-A4. Pracuji jako elektrikář v automobilovém průmyslu nákladních automobilů, kde jsme také prodejci značek TATRA Trucks CZECH a dále speciální nástavby na přání, kde jsme museli požádat o jinou firmu o vývoj hardwaru a pro daný typ zákazníka. Díky Vašemu ovladači bychom tyto věci zvládli sami a určitě bychom dokázali další udělat na nákup více kusů a vašich zařízení. Velmi bych ocenil vzorek zdarma.
