  how to control 16 relay using Python code
Posted by: admin - 10-15-2024, 12:16 AM - Forum: KinCony Server-Mini / Server-16 Raspberry Pi4 relay module - No Replies

Here’s a Python code that runs on Ubuntu and controls 16 relays connected to MCP23017 via I2C. This code uses the smbus2 library, so make sure to install it first (pip install smbus2).

Code:
import smbus2
import time

# MCP23017 Register definitions
IODIRA = 0x00  # Direction register for Port A
IODIRB = 0x01  # Direction register for Port B
OLATA = 0x14   # Output latch register for Port A
OLATB = 0x15   # Output latch register for Port B

# I2C Device Address
MCP23017_ADDRESS = 0x22

# Initialize I2C bus
bus = smbus2.SMBus(1)  # Raspberry Pi CM4 typically uses I2C bus 1

def setup_mcp23017():
    # Set Port A and Port B to output mode
    bus.write_byte_data(MCP23017_ADDRESS, IODIRA, 0x00)  # Set Port A to output
    bus.write_byte_data(MCP23017_ADDRESS, IODIRB, 0x00)  # Set Port B to output

    # Turn off all relays initially
    bus.write_byte_data(MCP23017_ADDRESS, OLATA, 0x00)  # Turn off all relays on Port A
    bus.write_byte_data(MCP23017_ADDRESS, OLATB, 0x00)  # Turn off all relays on Port B

def set_relay(relay_num, state):
    """
    Controls a specific relay
    relay_num: 1-16, corresponding to the 16 relays
    state: 1 to turn on, 0 to turn off
    """
    if relay_num < 1 or relay_num > 16:
        raise ValueError("Relay number must be between 1 and 16")

    if relay_num <= 8:
        # Control relays 1-8 on Port A
        current_state = bus.read_byte_data(MCP23017_ADDRESS, OLATA)
        if state == 1:
            current_state |= (1 << (relay_num - 1))  # Turn on the relay
        else:
            current_state &= ~(1 << (relay_num - 1))  # Turn off the relay
        bus.write_byte_data(MCP23017_ADDRESS, OLATA, current_state)
    else:
        # Control relays 9-16 on Port B
        relay_num -= 8
        current_state = bus.read_byte_data(MCP23017_ADDRESS, OLATB)
        if state == 1:
            current_state |= (1 << (relay_num - 1))  # Turn on the relay
        else:
            current_state &= ~(1 << (relay_num - 1))  # Turn off the relay
        bus.write_byte_data(MCP23017_ADDRESS, OLATB, current_state)

def test_relays():
    # Sequentially turn on and off each relay with a 1-second delay
    for i in range(1, 17):
        print(f"Turning on relay {i}")
        set_relay(i, 1)
        time.sleep(1)
        print(f"Turning off relay {i}")
        set_relay(i, 0)
        time.sleep(1)

if __name__ == "__main__":
    setup_mcp23017()
    test_relays()  # Test relays
Before running the script, install the smbus2 library:
pip install smbus2

Question Ghost trigger
Posted by: kbo - 10-12-2024, 10:40 AM - Forum: KC868-A64 - Replies (4)

Hi,

I have implemented a kc-868-a64 in my home. It works great. It is integrated with Home Assistant to do some automation but the kc-868-a64 works on itself (see config below)

But I have a problem. Sometime when a push button is pressed, the configured light goes on BUT an other, not configured light sometimes also goes on.
I have this for some push buttons, not all. 

I tried to troubleshoot it but I can't find the issue.
Is there any way to troubleshoot this issue or is this a known issue ?

I have impulse relays so most of the outputs will turn off again.

My ESP HOME config is attached (I have redacted some fields)

i want to receive 16 bytes data through rs485 port with kc868-a16s.
but the received value is strange.
please le me know what should i check.

void loop() {
  if (Serial2.available() > 0) {
    Serial.print("rs485 received value : ");
    Serial.println(Serial2.read());

  delay(1000);
}

Information How to Add an Extra Module for SD Card on the KC868-A6 Board?
Posted by: iagomendes - 10-10-2024, 09:48 PM - Forum: KC868-A6 - Replies (1)

I'm looking for information on how to add an extra module for an SD card to my KC868-A6 board. What are the necessary steps to connect the module and program it properly? Is there any specific code I should use to ensure that data recording works correctly? I appreciate any guidance or resources that can assist me in this process.

  KC868-AI - input as output HomeAssistant
Posted by: fbuffolo - 10-10-2024, 12:39 PM - Forum: KC868-AI - Replies (1)

Good morning,

in order to upgrade my home allarm system, I want to buy a KC868-AI. I have a question: I read that the dry contacts inputs can work as output with a KCS firmware; but can I use the input ad output also in Home Assistant?

I need one input as output in order to turn on the siren when one input is in allarm mode.

Thanks in advance.

  Hardware configuration:
  - RS485 communication using GPIO TX (32) and RX (35)
  - Modbus RTU protocol
  - Temperature and humidity values are stored in separate registers

  You must install the ModbusMaster library in Arduino IDE.
