Why my KC868 A4 after 2 days not working or stop working but the power led still on. It's must switch off the power then switch on the power it will work again. after 2 days it will stop working again.

Here are some documents of EC200U 4G module software

Hi there

I'm having an issue with getting the KC868-A6 RTC working.

I've taken the example code in the A6 thread as per below, and it returns an error of "Couldn't find RTC".

I've made sure that the I2C SDA and SCL pins are set correctly in the NodeMCU-32S config file.

The RTClib I've used is the Adafruit library below:
https://github.com/adafruit/RTClib

The battery has been installed into the socket on the board.  I've successfully coded up things so that the PCF8574 outputs and inputs to work so I know that the I2C SDA and SCL are working.

The comments in the example code mention the Wire lib, so I've tried including this as well, but it didn't fix the problem.

Any thoughts would be appreciated.


/*KC868-A6 DS1307 CODE*/
// Date and time functions using a DS1307 RTC connected via I2C and Wire lib
#include "RTClib.h"

RTC_DS1307 rtc;

void setup () {
  Serial.begin(115200);

#ifndef ESP8266
  while (!Serial); // wait for serial port to connect. Needed for native USB
#endif

  if (! rtc.begin()) {
    Serial.println("Couldn't find RTC");
    Serial.flush();
    while (1) delay(10);
  }

  if (! rtc.isrunning()) {
    Serial.println("RTC is NOT running, let's set the time!");
    // When time needs to be set on a new device, or after a power loss, the
    // following line sets the RTC to the date & time this sketch was compiled
    rtc.adjust(DateTime(F(__DATE__), F(__TIME__)));
    // This line sets the RTC with an explicit date & time, for example to set
    // January 21, 2014 at 3am you would call:
    // rtc.adjust(DateTime(2014, 1, 21, 3, 0, 0));

We have designed KC868-E8T with Tuya module , 4G LTE module and ESP32, the 8 channel removable relay board.

You can integrate KC868-E8T to home assistant by ESPHome use follow resource:

a. 8 relay relay, 8 channel digital input for switch panel. 4 channel AC220V energy meter (BL0939 energy chip) for load's voltage, current, power, power consumption. DS18B20 temperature sensor.

b. support use Tuya mobile phone application remote control 8 relay by internet , monitor 4 channel load's energy meter and temperature by DS18B20 sensor.

Hello.

I need to know how to completely reset the H23B, Seria number H32B200812520, I don´t have access to it and I can´t configure it for WEB access.
It´s very old firmware, and never been done, which if you have i want update.
I couldn´t find the manual or the PC software on the website kincony.
Thanks

Hi there
I'm trying to get the relays to work on a KC868-A6.
I'm using the KC868-A8 example source code as the basis for this and modified it as shown below:

#include “Arduino.h”
#include “PCF8574.h”

#define I2C_RELAYS_ADR 0x24
PCF8574 pcf(I2C_RELAYS_ADR);

void setup() {
Serial.begin(115200);
Serial.println(F(“Start Kincony KC868-A6 Relays example…”));
pcf.pinMode(P0, OUTPUT);
pcf.pinMode(P1, OUTPUT);
pcf.pinMode(P2, OUTPUT);
pcf.pinMode(P3, OUTPUT);
pcf.pinMode(P4, OUTPUT);
pcf.pinMode(P5, OUTPUT);
Serial.print(“Init PCF8574… “);
if (pcf.begin()){Serial.println(F(“Ok”));}
else {Serial.println(F(“Error”));}
}

void loop() {
pcf.digitalWrite(P0, HIGH);
Serial.print(F(“Relay #”)); Serial.print(P0); Serial.println(F(” ON”));
delay(10000);
pcf.digitalWrite(P0, LOW);
Serial.print(F(“Relay #”)); Serial.print(P0); Serial.println(F(” OFF”));
delay(10000);
}


Using this example, the pcf.begin statement fails and returns "Error".
Looking at the schematic diagram for the KC868-A6, the I2C SDA is set to pin 26, and the SCL is set to pin 23.  By default the PCF8574 library will default to other values, so I tried changing the statement below to the following which matches the format noted in the readme file for the PCF8574 library
 PCF8574 pcf(0x24, 26, 23);

This didn't work either and so I tried the various I2C scanners and they don't find any I2C device.

I've also ensured that the relevant pins_arduino.h file has been edited to reflect the correct SDA and SCL pin values.

One other thing I have noticed is on startup there is a strange error, see below:

The highlighted line in red looks odd but I can't find anything online to help. 

Any assistance would be appreciated.
