[KC868-A16] Problem with PCF8574 I/O

Posted by: alessiovietri - 07-04-2023, 12:59 PM - Forum: KC868-A series and Uair Smart Controller - Replies (3)

Hello, i'm tryng to read inputs from the PCF8574 channels. This is my code:

Code:
//Apple Homekit for KC868-E16S/KC868-E16T

//first time to use: use serial port send "W" to config wifi ssid and password

//if you want to eraser all data, re-config, use serial port send "E"

//default qrcode is 46637726

#include "HomeSpan.h"

#include "PCF8574.h"

PCF8574 pcfInLeft(0x22);

void pcfInit(){

  pcfInLeft.pinMode(P0, INPUT);

  pcfInLeft.pinMode(P1, INPUT);

  pcfInLeft.pinMode(P2, INPUT);

  pcfInLeft.pinMode(P3, INPUT);

  pcfInLeft.pinMode(P4, INPUT);

  pcfInLeft.pinMode(P5, INPUT);

  pcfInLeft.pinMode(P6, INPUT);

  pcfInLeft.pinMode(P7, INPUT);

  if (pcfInLeft.begin()) {

    Serial.println("pcf OK");

  }

  else{

    Serial.println("pcf ERROR");

  }

}

void setup() { 

  Serial.begin(115200);

  delay(1000);

  pcfInit();      

} // end of setup()

//////////////////////////////////////

void loop(){

  uint8_t in0 = pcfInLeft.digitalRead(P0);

  Serial.println("in0");

  Serial.println(in0);

  uint8_t in1 = pcfInLeft.digitalRead(P1);

  Serial.println("in1");

  Serial.println(in1);

  uint8_t in2 = pcfInLeft.digitalRead(P2);

  Serial.println("in2");

  Serial.println(in2);

  uint8_t in3 = pcfInLeft.digitalRead(P3);

  Serial.println("in3");

  Serial.println(in3);

  uint8_t in4 = pcfInLeft.digitalRead(P4);

  Serial.println("in4");

  Serial.println(in4);

  uint8_t in5 = pcfInLeft.digitalRead(P5);

  Serial.println("in5");

  Serial.println(in5);

  uint8_t in6 = pcfInLeft.digitalRead(P6);

  Serial.println("in6");

  Serial.println(in6);

  uint8_t in7 = pcfInLeft.digitalRead(P7);

  Serial.println("in7");

  Serial.println(in7);

  delay(1000);

} // end of loop()

But the method pcfInLeft.begin() always returns false and the inputs are always read as off. What's wrong?

Thanks in advance

I forgot to mention that the KCS software knows when the inputs go on, so it's not a wiring-related problem

KC868-A8 Touch wall panel indication working reverse and temperature sensor

Posted by: vijjav - 07-03-2023, 02:51 PM - Forum: KC868-A8 - Replies (11)

Hi Xu Wei,

Good day, I need assitance for two things.

1. My DHT sensor not reading temperature and the ESPHome log messages output below.

Code:
[20:03:03][C][dallas.sensor:075]: DallasComponent:

[20:03:55][D][sensor:094]: 'study_room_temperature_sensor': Sending state nan °C with 1 decimals of accuracy

I have tried connecting my DHT11 sensor to both S1 & S2 input terminals and getting the same error for reading the temperature.

2. I am trying to make the Touch Wall Panel Switch glow when turning on inputs, I know KC868-A8 not having a digital input, but i made a small adjustment and patched a wire from relay 1 GND output terminal in the PCB and connected to Switch D1. K1 is connected to input.

All looks good, but the LED is turning ON when the switch 1 is turned off and LED is Off when switch 1 is turned ON.

Connection Details:

A8 Board Input 1 --> Wall Switch K1
A8 Board Relay 1 Digital Input GND soldered from PCB --> Wall Switch D1
A8 Board S1 --> DTH11 Data terminal , VCC and Ground connected in the S1-S4 terminal block VCC & GND.

My ESPHome code block is a below, I tried several 'Inverted : true" at switch component and binalry_sensor component in yaml file, but I am missing some basic part.

Need your help to overcome my Two issues.
